ABOUT US
Since 2013, we’ve been building a CRM that gets out of your way and helps your team sell more, faster. Now we’re building AI into every part of it, so Close does the busywork and your team does the selling. No manual data entry, no 10-click workflows. Just communication-first, AI-powered sales software designed to help you succeed and scale.
We're bootstrapped and profitable which means we answer to our customers and play by our rules. We're proud of our 130-person, 100% remote team, focused on building Close so that no small, scaling business fails because it can't figure out sales.
OUR STACK
Our backend tech stack consists primarily of Python Flask web apps with our TaskTiger https://github.com/closeio/tasktiger scheduler handling many of the backend asynchronous task processing chores. Our data stores include MongoDB, PostgreSQL, Elasticsearch, and Redis. The underlying infrastructure runs on AWS using a combination of managed services like EKS, MSK, RDS and ElastiCache and non-managed services running on EC2 instances. We have CI/CD pipelines that build Docker images, run automated tests and deploy to Kubernetes clusters. We also use these images in our local development environment allowing coding locally against all of our services. We have a well-documented public API https://developer.close.com/ that is consumed by our front-end JavaScript app as well as numerous integrations. Our infrastructure is heavily automated using Terraform, Ansible and other AWS tools.
We love open sourcing our code and ideas on our GitHub https://github.com/closeio and on The Making of Close https://making.close.com/, our behind-the-scenes Product & Engineering blog. Check out our open source projects like SocketShark https://github.com/closeio/socketshark, TaskTiger https://github.com/closeio/tasktiger, LimitLion https://github.com/closeio/limitlion and ciso8601 https://github.com/closeio/ciso8601.
AI is both how we build and what we ship, and that's reshaped what engineering looks like. This is a transformation we’re embracing and find deeply exciting.
ABOUT THE ROLE
Close runs on Python: Flask web apps, TaskTiger, billions of MongoDB documents, a public REST API that customers and external agents both build on. Four product teams ship features on top of that every week. Backend Platform owns the foundation underneath it all.
As an Engineer on our Backend Platform team, you’re building for other engineers. When a product team adds a new API endpoint, most of what they write isn't their feature — it's wiring: authentication, permissions, rate limiting, the shape the endpoint has to take so it looks like every other endpoint when you squint. Multiply that across telemetry, eventing, database migrations, authorization, and local development, and you get the problem this team exists to solve: make the paved road faster to walk than the trail.
The other half of the team's mandate is the AI development platform. We've built DevDawg, cloud-based development environments preconfigured for our entire application stack and our engineering practices, and Spice, our extension layer on top of a coding agent that runs internal review workflows and root cause analysis. Spice is hooked into GitHub and can already approve mergeable pull requests on its own for simple changes. This team is responsible for expanding what it can safely handle.
This is a new team. You would be one of the first hires, and you'd have unusual influence over what the team owns and how it operates.
One thing to know: we do move people between teams as the work shifts. Most engineers here end up on more than one team over their time at Close — this team is where you'd start, but over time you'll likely have the opportunity to work on many different projects.
This role is open at the Senior and Staff levels. You don't need to pick one when you apply: we'll calibrate together during the process.
YOU ARE
- A seasoned Python engineer. Python is our backbone and it matters in this role more than on other teams at Close. Architectural patterns don't port cleanly between languages, and you'll be setting the patterns. Go, Rust, or TypeScript alongside it is welcome.
- Drawn to meta-problems. This team doesn't ship features to customers; it changes how features get built.
- AI-native in production. You've shipped meaningful LLM-backed or agentic work to real users. For a team building AI tooling that other engineers depend on, this is foundational to the role.
- Working with AI in your day-to-day. You use coding agents in your own workflow and have a real POV on where they help and where they get in the way. On this team, your POV becomes the product. We fund best-in-class developer tools and treat experimentation as part of the work.
- Fluent in observability and production practice. Telemetry, metrics, tracing, alerting, Sentry ownership, what production-ready actually means. You've been the person who made a system legible when it broke.
- Opinionated about API design. You've shipped internet-facing APIs and you think about who's on the other end — apps, agents, humans reading docs — and what each needs.
- Battle-tested. You've debugged incidents where latency budgets didn't hold, owned a system everyone else relied on, or carried a pager for something with real customer impact.
- A builder first. You'd rather get a rough v1 in front of five engineers than spend three weeks on abstractions.
- Energized by internal customers. Your users are a Slack DM away. You'll talk to them directly instead of through a PM, and you'll use most of what you build yourself.
YOU WILL
- Expand DevDawg and Spice. Cloud development environments for our full stack, paired with automated review and root-cause tooling that can approve real pull requests. Making that safe enough to cover more of our review surface is one of the team's biggest projects.
- Build the paved roads for our API layer. REST blueprints, GraphQL schema, OpenAPI, realtime, and the auth and permission plumbing that every endpoint needs. Consistent patterns are what make shared utilities possible.
- Modernize the backend framework layer. Web and async compute frameworks, performance, and migration paths (Flask → FastAPI, among others) — with clear defaults, examples, and migrations teams can adopt without asking permission.
- Own how we see production. Observability, metrics, alerting, and the readiness bar teams meet before shipping. When the same issues keep showing up in incident reviews, you make sure the underlying cause gets owned rather than re-triaged.
- Ship shared backend services and primitives. Eventing patterns and the event log, database-change safety and migration guardrails, delegated access and auditability, the internal admin framework and support-facing APIs.
- Set the guardrails for coding agents in our backend. Static analysis, linting, hooks, test harnesses — the constraints that make agent-written code safe to merge at volume.
- Partner across the org. Infrastructure owns the substrate (AWS, Kubernetes, datastores); you own the application layer on top.
Tech you'll touch: Python, Flask, FastAPI, GraphQL, TaskTiger, Rust, TypeScript, Kafka, Redis, MongoDB, PostgreSQL, Elasticsearch, Docker, Kubernetes, GitHub Actions — plus whatever coding agent ships next.

THE OPPORTUNITY
Apollo Research works with most frontier AI companies (OpenAI, Anthropic, Google, Meta, Thinking Machines and others) to test their models before deployment and collaborate on fundamental scheming research. Our coding agent security product, Watcher, is deployed in production and monitors billions of agent tokens per month across engineering teams at agent-building scale-ups and enterprises.
Security exists at Apollo to safeguard the trust our lab partners place in us and to enable that research. Our own team runs around 400 billion tokens a month through AI agents, which makes Apollo both a target and a testbed. We’re hiring Security Engineers to join the Infra & Security Team.
In this role, you will design, implement, and deploy the security controls that keep Apollo secure, and make the secure path the default path for everyone. You will build the security layer for a novel insider risk that didn't exist before.
RESPONSIBILITIES
Design, build, and operate Apollo's core security controls: identity and access management, infrastructure and cloud security, endpoint management, and incident response.
Build paved roads that make the secure path the default, easy path
Establish and advocate for security practices across Apollo, and build the organizational trust needed for people to adopt them, communicating security decisions and tradeoffs clearly along the way.
Evaluate vendors and tooling, make build-vs-buy calls on security infrastructure, and assess vendor security posture before adoption.
Lead major security projects end to end, from ideation through implementation and rollout.
Collaboratively define and shape the security roadmap and priorities.
KEY REQUIREMENTS
Must-haves
5+ years in security roles
in a hands-on technical capacity (not purely GRC/compliance). You'd need to be able to think structurally about threat modeling and failure modes. You need to be able to read code, understand infrastructure, and evaluate technical controls.
Engineering mindset.
You treat security as an engineering problem. You are capable of, and willing to, build custom solutions when the task demands it, rather than relying on 'glueing' together off-the-shelf tools. You prioritize automation and systems-level thinking to scale security, and you are comfortable leveraging AI to accelerate development.
Direct experience with application security, cloud security, or product security.
Ideally you’ve owned or significantly contributed to the security posture of an organisation that handles sensitive customer data.
Influence without authority.
You have a track record of building buy-in for security practices and being trusted by non-security people.
Startup pace.
You are excited about a fast-moving environment, comfortable with ambiguity and changing priorities, and willing to grind when it matters.

ABOUT THE TEAM
The Infra and Security team is currently led by Rusheb Shah and consists of Glen Rodgers and Steven Lee. You will work closely with Security Researchers we’re hiring for as well as technical staff from the Scheming Research and Product team. You can find our full team here.
ABOUT APOLLO RESEARCH
The rapid rise in AI capabilities offers tremendous opportunities, but also presents significant risks. At Apollo Research, we're primarily concerned with risks from Loss of Control, i.e. risks coming from the model itself rather than e.g. humans misusing the AI. We're particularly concerned with deceptive alignment / scheming, a phenomenon where a model appears to be aligned but is, in fact, misaligned and capable of evading human oversight.
We work on the science of scheming, detection of scheming (e.g. building evaluations), and scheming mitigations (e.g. anti-scheming). We also work on control and monitoring research (see our scalable monitoring agenda). We work closely with many frontier AI companies, such as OpenAI, Anthropic, Google, Meta, Thinking Machines and others, e.g. to test their models and collaborate on the science of scheming. At Apollo, we aim for a culture that emphasizes truth-seeking, being goal-oriented, giving and receiving constructive feedback, and being friendly and helpful. If you're interested in more details about what it's like working at Apollo, you can find more information here.
We also build a coding agent security product called Watcher that secures agent deployments in companies. Our goal is to reduce the probability of catastrophic incidents by securing coding agents, learning about their real-world risks, and publishing our research on how to build these control systems most effectively.
Equality Statement: Apollo Research is an Equal Opportunity Employer. We value diversity and are committed to providing equal opportunities to all, regardless of age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, or sexual orientation.
HOW TO APPLY
Please complete the application form with your CV. The provision of a cover letter is neither required nor encouraged. Please also feel free to share links to relevant work samples.
About the interview process: Our multi-stage process includes a screening interview, a take-home test (approx. 2-3 hours), 3 technical interviews, and a final interview with Marius (CEO). There are no leetcode-style general coding interviews. You may use AI tools on the take-home; we judge the result the way we'd judge any contributor's work, so you are responsible for the quality of everything you submit. If you want to prepare, we suggest building simple monitors for coding agents and running them on your own Claude Code / Cursor / Codex / etc. traffic.
Your Privacy and Fairness in Our Recruitment Process: We are committed to protecting your data, ensuring fairness, and adhering to workplace fairness principles in our recruitment process. To enhance hiring efficiency, we use AI-powered tools to assist with tasks such as resume screening. These tools are designed and deployed in compliance with internationally recognized AI governance frameworks. Your personal data is handled securely and transparently. All resumes are screened by a human and final hiring decisions are made by our team.

PERPLEXITY API PLATFORM
Perplexity innovates at the frontier of AI infrastructure, search, and orchestration to serve the world's most discerning users. The Perplexity API Platform brings our technology to the world's most discerning developers. From exabyte-scale knowledge indexes to codegen-first agent runtimes, the building blocks behind Perplexity's applications are some of the most battle-tested AI systems in the industry.
We believe these same building blocks can and should power the aspirations of builders everywhere. It's one thing to solve planet-scale retrieval, long-horizon orchestration, and other foundational AI challenges within a single product ecosystem. The true measure of success is to turn those solutions into elegant APIs that delight developers and agents alike. Our API Platform delivers frontier intelligence to thousands of customers: startups, trillion-dollar enterprises, U.S. and allied governments, and everyone in between.
We've achieved incredible scale, yet we're just getting started. Join us to build tools for curious minds.
ABOUT THIS ROLE
Perplexity is seeking strong engineers with a passion for delivering frontier intelligence and infrastructure to developers. Our company builds technology that reshapes how people search, reason, and interact with the world around them. Week after week, we observe increasing demand for programmatic interfaces to that technology. The API Platform engineering team is charged with designing, implementing, and scaling these interfaces.
As a member of our team, you'll work on an eclectic portfolio spanning distributed systems, performance optimization, agent orchestration, and frontier topics that often change with each passing month. Throughout this work, you'll prioritize great developer and agent experience alike. You'll also define technical strategy for how we scale to meet compounding growth exponentials (number of customers, agents per customer, compute/retrieval per agent, etc.).
KEY RESPONSIBILITIES
- Design, build, and operate mission-critical APIs that provide our customers the building blocks for frontier intelligence.
- Own and evolve the API gateway and routing layer: authentication, authorization, rate limiting and quotas, usage metering, and request routing across heterogeneous upstream services.
- Build the paved road for API services: standardized service scaffolding, container builds, CI/CD, Kubernetes and Helm deployment, and progressive rollouts with fast rollback, so a new API product goes from idea to production in days, not weeks.
- Build API governance into the platform: contract-first schemas, breaking-change detection in CI, versioning and deprecation workflows, and SDKs and documentation generated from a single source of truth.
- Unify cross-cutting capabilities (billing and usage, rate limiting, organization and identity settings, analytics and observability) so every API product gets them by default instead of rebuilding them.
- Ensure low latency and high throughput through aggressive performance optimization (including on upstream systems).
- Harden system security and reliability across heterogeneous compute environments, and operate what you build: SLOs, on-call, and incident response.
- Collaborate across teams to bring novel frontier capabilities into the API Platform, and partner with infrastructure teams on compute, networking, secrets, and security.
- Continually reimagine the customer needs of tomorrow (and the architectures to serve those needs), while faithfully serving the customer workloads of today.
- Uphold engineering excellence through design reviews, code quality, and internal documentation.
QUALIFICATIONS
- 5+ years of backend engineering experience with Python, Go, or Rust, including significant time building platforms or infrastructure used by other engineering teams.
- Strong understanding of high-traffic API design: schema evolution & versioning, idempotency, authentication patterns, rate limiting, and performance tuning.
- Hands-on experience building and operating API gateways, reverse proxies, or routing layers: authentication and authorization, rate limiting and quotas, request routing, traffic shaping, and per-request observability.
- Experience building API governance tooling: contract-first API design, breaking-change detection and API linting in CI, versioning and deprecation workflows, and SDKs and documentation generated from the contract.
- Platform depth across the build and deploy path: you have owned CI/CD pipelines, container builds and base images, infrastructure as code, and progressive delivery (canary or blue-green) on a major cloud.
- A track record of owning a platform end to end: identifying the need, designing it, aligning the teams that depend on it, shipping it, and operating it, while raising the engineering bar for the teams building on it.
- Strong customer empathy and product sense, ensuring the APIs you build are ergonomic, well-documented, and easy to adopt for developers and agents alike.
Strong plus:
- Experience with modern AI APIs (including latency tuning, streaming, model orchestration, emerging technical standards).
- Usage-based billing and metering systems, multi-tenant organization and identity models, and usage analytics pipelines.
- Observability for API platforms: structured logging pipelines, metrics, tracing, and SLO tooling.

ROLE SUMMARY
Temporal’s reliability is foundational to our value proposition, and as more customers run mission-critical workloads on Temporal, we need the ability to validate changes under production-like conditions and realistic failure modes before they reach production.
As a Staff Software Engineer on the Test Systems & Tooling team, you will lead technical initiatives that make sophisticated system-level testing practical across Engineering—spanning production-representative environments, workload replay/generation, and repeatable failure-mode testing. You’ll build platforms and tooling that enable teams to reproduce and prevent the kinds of issues that only emerge from complex interactions between workload, scale, configuration, and multi-tenant behavior.
WHAT YOU'LL DO
- Build production-like test environments: Design and evolve tooling that makes it easy for engineers to spin up test cells that resemble production topology, configuration, and behavior, in partnership with Cloud/Infrastructure.
- Enable production-representative workloads: Build capabilities for workload generation, multi-tenant testing, stress/load testing, and (where appropriate) traffic replay or replay-like systems to reproduce production behaviors in controlled environments.
- Make failure-mode testing repeatable: Create tooling for injecting and validating failure conditions (latency, dependency faults, resource exhaustion, degraded-state recovery, and region-level failure scenarios) so we test them deliberately—not just learn from production.
- Drive system-level test coverage: Identify high-impact system-level scenarios that are currently hard to test, and implement (or partner with the right teams to implement) repeatable coverage that’s incorporated into continuous and/or release validation.
- Build shared frameworks and paved paths: Provide opinionated libraries, harnesses, and patterns that make it easier for product teams to write high-quality system and integration tests consistently.
- Raise the technical bar through leadership: Mentor engineers and influence testing strategy across the org through design docs, code reviews, and cross-team collaboration.
- Partner across Engineering: Work closely with Reliability and Release Engineering to turn incident learnings into durable pre-production test coverage and to integrate validations into the release pipeline.
WHAT YOU'LL BRING
- Strong software engineering fundamentals and experience building and operating production-quality systems (platforms, infrastructure, developer tooling, or distributed systems).
- Demonstrated technical leadership: leading ambiguous, cross-team initiatives; driving alignment; and delivering durable systems that other teams rely on.
- Experience designing for observability, debuggability, and operational readiness (metrics, logs, tracing, safe rollouts, and failure analysis).
- Comfort working across organizational boundaries—collaborating with Cloud/Infrastructure, Reliability, Release Engineering, and product teams to land outcomes.
- Strong written communication skills (design docs, testing strategy proposals, and documentation that scales adoption).
NICE TO HAVES
- Experience with chaos engineering, fault injection, workload replay/shadowing, performance testing, or multi-tenant test strategy.
- Experience building internal platforms used broadly across an engineering org (paved roads, self-serve environments, shared frameworks).
- Familiarity with measuring engineering/system outcomes (e.g., signal quality, coverage gaps closed, incident-to-coverage time, adoption).
