Location: Remote - Americas Who We Are: Alpaca is a US-headquartered, global leader in agent-first brokerage infrastructure for stocks, ETFs, options, crypto, fixed income, 24/5 trading, and more. Amongst our subsidiaries, Alpaca is a licensed financial services company, serving hundreds of financial institutions across 40 countries with our institutional-grade APIs. This includes broker-dealers, investment advisors, wealth managers, hedge funds, and crypto exchanges, totalling over 10 million brokerage accounts. Our global team is a diverse group of experienced engineers, traders, and brokerage professionals who are working to achieve our mission of opening financial services to everyone on the planet. We're deeply committed to open-source contributions and fostering a vibrant community, continuously enhancing our award-winning, developer-friendly API and the robust infrastructure behind it. Alpaca is proudly backed by $400 million in funding from top-tier global investors including Portage Ventures, Spark Capital, Tribe Capital, Social Leverage, Horizons Ventures, Opera Tech Ventures, SBI Group, Derayah Financial, Unbound, Peak XV, Elefund, and Y Combinator. Our Team Members: We're a dynamic team of 400+ globally distributed members who thrive working from our favorite places around the world, with teammates spanning the USA, Canada, Japan, Hungary, Nigeria, Brazil, the UK, and beyond! We're searching for passionate individuals eager to contribute to Alpaca's rapid growth. If you align with our core values—Stay Curious, Have Empathy, and Be Accountable—and are ready to make a significant impact, we encourage you to apply. Your Role: Alpaca is already the infrastructure layer that hundreds of partners build on for execution. Nobody else is both the execution layer and the data layer - and that makes us the natural one-stop shop for brokerage plus market data. We're hiring a Lead Product Manager to own that second half: define and grow Alpaca's market data business as a standalone, revenue-generating product line. We're seeking a Lead Product Manager, Market Data to define and own Alpaca's market data strategy - both as a capability that powers our platform and as a standalone, revenue-generating product line. This role is equal parts strategy and delivery. You'll decide what data we source, how we package and price it, what we build versus buy - and then ship the APIs, feeds, and tooling that partners and internal teams depend on every day. What You'll Walk Into You won't be starting from zero - you'll be owning live problems: Multiple new exchange onboardings in flight, each with its own licensing, entitlement, and redistribution constraints. A pricing and packaging model that needs rethinking as we expand across asset classes and geographies. Partners asking for data we don't serve yet - consolidated feeds, historical datasets, derived analytics - you'll be building those requests against cost and commercial upside. Internal teams (trading, algo routing, compliance, clearing) consuming market data with no product owner ensuring coverage keeps pace. Things You Get To Do Negotiate or inform negotiations on exchange licensing, redistribution rights, and entitlements as Alpaca onboards new exchanges and asset classes - you'll talk to vendors and global venues directly. Assess build-vs-buy for data infrastructure: where do we source from third parties, where do we invest in proprietary collection and normalization, and where do we create derived or value-added data products. Build the commercial model: define pricing and packaging (real-time vs. delayed, depth-of-book tiers, historical datasets, derived analytics) and work with sales to grow market data revenue. Own the competitive position: understand how dedicated market data providers price and differentiate, and identify where Alpaca's bundled brokerage-plus-data model creates a defensible edge. Own the developer experience for market data APIs (REST, WebSocket/SSE, historical endpoints) - coverage, latency, reliability, and documentation that developers actually want to read. Lead partner discovery: understand what data capabilities are table-stakes vs. differentiating for neobrokers, RIAs, hedge funds, and crypto exchanges, and turn that into prioritization. How We Take Care of You: Competitive Salary & Stock Options Health Benefits New Hire Home-Office Setup: One-time USD $500 Monthly Stipend: USD $150 per month via a Brex Card Alpaca is proud to be an equal opportunity workplace dedicated to pursuing and hiring a diverse workforce.

We build on open infrastructure, global money, and internet capital markets to deliver better financial services to businesses, individuals, and developers. Our products span the company’s mission: Squads Multisig helps teams secure and manage assets on Solana; Altitude gives businesses a global account to run their financial operations; and Fuse brings stablecoins and tokenized assets to personal finance. More than 450 teams use Squads Multisig to secure over $10 billion in value. Our investors include Haun Ventures, Multicoin Capital, Electric Capital, Coinbase Ventures, Toly, Mert, and others. THE ROLE You’ll own identity and endpoint security across Squads, working closely with our Head of Security. That means making sure the right people have the right access, company devices meet a consistent security baseline, and new tools can be adopted with a clear understanding of their risks. This is a hands-on role. You’ll run the day-to-day systems, respond when something looks wrong, and build the access reviews, standards, and processes we’ll need as the company grows. We’re looking for someone who thinks like an attacker, makes sound calls under pressure, and can help the team move quickly while keeping the bar high. WHAT YOU’LL OWN IDENTITY & ACCESS - Administer our identity provider and SSO, enforce MFA and phishing-resistant authentication, and improve how access is granted and removed - Build periodic access reviews and apply least privilege across critical systems - Manage access provisioning and offboarding for employees and contractors ENDPOINTS & IT OPERATIONS - Own MDM and EDR coverage across the device fleet, with clear configuration standards and security baselines - Handle device provisioning, access requests, and the IT work that keeps the team operating securely - Automate repetitive security and IT workflows where it improves coverage or reduces manual work RISK & RESPONSE - Partner with the Head of Security on vendor risk assessments - Assess new SaaS tools and AI integrations before adoption, and give teams practical guidance on how to use them safely - Act as a first responder for identity and endpoint incidents: investigate, contain, document, and escalate when needed - Help define and maintain security policies as the program matures YOU MIGHT BE RIGHT FOR THIS IF - You’ve owned identity and endpoint systems in practice, including the messy work of getting coverage and adoption across a team - You spot how an attacker could use a weak access path, unmanaged device, or new integration before it becomes an incident - You can distinguish a real risk from a theoretical one and explain your recommendation clearly - You’ve responded to incidents and can stay calm, gather facts, and make the next call under pressure - You write guidance that non-technical teammates can follow - You’ve helped build a security function early, when the process and tooling still needed to be defined - You’re comfortable handling an access request or laptop issue one hour and improving a company-wide control the next REQUIREMENTS - Hands-on experience operating an enterprise identity platform, including SSO, MFA, and access policies - Experience managing MDM and EDR tooling across a device fleet - Experience responding to security incidents, compromises, or suspected breaches - Ability to assess vendor and integration risk, including risks introduced by AI tools - Scripting ability in Python or Bash for automation and basic tooling - Strong written communication and the judgment to work independently - Experience with blockchain or Web3 threats, cloud security, SIEM and detection engineering, or AI agents used in security operations is a plus. WHY THIS MIGHT BE INTERESTING Squads builds financial products for businesses, individuals, and developers on new money rails. The security work spans all of them. You’ll have ownership over the systems people use every day, a direct hand in how the company adopts new tools, and the chance to build controls that scale with the business. You’ll work closely with the Head of Security in a small team where good judgment has an immediate effect. If you like building the security program while also operating it, you’ll have room to do both here. Small team, high standards. Learn more about our core values here https://squads.xyz/company.

Our remote-first team is globally distributed around the world: USA , UK , the Netherlands , Serbia , and more. We are headquartered in Amsterdam. About the Position Toloka is growing rapidly, adding new platforms and infrastructure across multiple cloud environments. We are hiring a senior, hands-on security engineer to own infrastructure security and vulnerability management: Kubernetes and service-mesh security, cloud hardening, and vulnerability remediation. This is a senior, self-directed role. It requires the ability to define scope and drive execution independently, with ownership of core security tooling and processes from day one. What you'll actually do Own vulnerability management. Operate and maintain the vulnerability-management platform. Ensure container images are scanned and patched on a defined cadence. Maintain supply-chain scanning tooling and its severity-classification configuration. Define and enforce remediation SLAs. Own cloud security across multiple providers. AWS, GCP, and Azure hardening, logging, and service-account governance. Own Kubernetes and service-mesh security. Operate the service mesh and maintain the policy-as-code rollout so that policy is enforced automatically. Audit and secure infrastructure in newly added environments. Review build pipelines and infrastructure in newer parts of the business as they come online, and remediate findings. Contribute to security architecture and design review. Review new integrations and internal systems, including AI agents running in production, for security risk. Support workforce and endpoint security. Contribute to VDI and browser-isolation initiatives as the program matures. Use agentic tooling in your workflow. Use coding agents for first-pass review of infrastructure-as-code, container configuration, and cloud policy, verifying findings against source configuration before acting on them. Key Priorities for the First 6 Months The first six months focus on establishing full ownership of infrastructure and vulnerability management. Weeks 1–2 - Onboard to the cloud environment, Kubernetes architecture, and existing security tooling. Month 1 - Establish ownership of the vulnerability-management process; findings triaged and remediated on a defined cadence. Month 2 - Complete configuration of supply-chain scanning tooling; implement automated image scanning and patching; deploy initial policy-as-code rules. Month 3 - Complete policy-as-code rollout in at least one environment; begin infrastructure audits in newly added environments. Month 4 - Close outstanding cloud logging and service-account gaps; establish and enforce a documented multi-cloud hardening baseline. Months 5–6 - Full ownership of infrastructure and cloud security as a domain; independently deliver security-architecture design reviews. Core Tech Stack Kubernetes and service mesh, policy-as-code tooling (Kyverno/OPA), Terraform, AWS/GCP/Azure, vulnerability-management and supply-chain scanning platforms, container tooling, CI/CD, and Git. Detections and access rules are managed as code through pull requests. Familiarity with coding/agentic tools for infrastructure review is expected. What We Evaluate Production experience hardening cloud infrastructure - IAM, logging, service accounts, network security, on at least one major cloud provider (multi-cloud experience is a plus). Kubernetes and container security - service mesh (Cilium, Istio, or similar) and policy-as-code (Kyverno, OPA, or similar). Vulnerability-management experience - SCA/SAST tooling and SLA-driven remediation practice. Fluency with coding agents - experience using agentic tools for infrastructure-as-code review or investigation work, and verifying their output. Ability to work independently at a senior level - defining scope and priorities without detailed direction. Clear written and verbal communication - able to run design reviews and communicate risk to engineers and leadership. Nice to Have, None Required Experience securing multi-tenant or multi-identity-domain environments; supply-chain security tooling (SBOM, Socket, JFrog, or similar); secure-SDLC or AppSec experience; Terraform/IaC at scale; relevant certifications (e.g. AWS/GCP/Azure security specialties, CKS). What We Can Offer Contract (B2B) collaboration , with a path into a project team if things go well; Flexible, fully remote schedule ( 40 hours per week ); Work at the leading edge of AI development, alongside a dedicated and dynamic team of experts; Projects with customers that are AI industry leaders and well-known household names; Friendly community.

Location: New York, NY Workplace: Hybrid ABOUT THE COMPANY Rain is the global stablecoin payments platform for enterprises, neobanks, platforms, developers, and AI agents. Our technology allows partners to move, store, and use stablecoins instantly and compliantly through global payment cards, rewards, on/offramps, wallets, and cross-border rails. As both a Visa and Mastercard Principal Member, Rain issues cards that work at more than 175 million merchant locations in over 220 countries and territories. Built natively for stablecoins and trusted by more than 100 organizations worldwide, Rain delivers secure, scalable infrastructure that makes money move freely and instantly around the world. You will have the opportunity to deliver massive impact at a hypergrowth company backed by some of the top investors in fintech, crypto, and SaaS. In January 2026, we closed a $250M Series C led by ICONIQ, valuing Rain at $1.95B, with Sapphire Ventures, Dragonfly, Bessemer Venture Partners, Galaxy Ventures, FirstMark, Lightspeed, Norwest, and Endeavor Catalyst also participating. If you're curious, bold, and excited to help shape a borderless financial future, we'd love to talk. OUR ETHOS We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company. About the Role AI agents are already booking travel, subscribing to software, running procurement end to end, and moving money on behalf of users — much of it through Rain. Our Agent Control Layer is the governing surface for that activity: it enforces approved counterparties, amounts, merchants, and task scope at initiation, before a transaction ever occurs, rather than reconciling damage after the fact. We are hiring a Senior Product Manager to own that platform. This is a 0-to-1 role inside a category being defined in real time. You will own the developer-facing surface — APIs, SDKs, controls, docs — that teams building agents use to give them spending power safely. McKinsey projects $3–$5 trillion in global agentic commerce by 2030. The primitives that make it trustworthy have not been built yet. You will build them. You will report to the Head of Product and work daily with engineering, risk and compliance, network partnerships, and the developers shipping on us. What you'll do • Define the primitives for agent authority: spend scopes, merchant and counterparty allowlists, velocity and amount ceilings, task-bound credentials, human-in-the-loop approvals, and clean revocation. • Own scoped virtual cards for agents — cards provisioned for a single merchant, amount, and task, retired the moment the task completes. • Extend the rest of Rain's stack (wallets, virtual accounts, onramps, offramps, cross-border payments) to agent initiators within the parameters our customers define. • Treat the API as the product. Own endpoint design, error semantics, idempotency, webhooks, sandbox and simulation tooling, SDKs, and reference agents. • Own documentation and the onboarding path with the same rigor as the product itself. Time-to-first-authorized-agent-transaction is your metric. • Run a tight design-partner loop with agent builders — read their integration code, sit in their debugging sessions, ship against what you find. • Build the roadmap from first principles: form a thesis on where agentic commerce goes next, sequence bets accordingly, and kill what isn't working quickly. • Partner with risk and compliance on Know Your Agent — agent identity, attestation, delegated authority, auditability, and dispute handling in a world where the cardholder wasn't the one who clicked. • Represent Rain's technical point of view in Agentic Payments Alliance working groups and with Visa, Mastercard, and stablecoin partners as standards take shape. • Write the specs, launch posts, and positioning that teach the market what controlled agentic payments actually means. You’ll likely succeed if you have • 8+ years in product management, with meaningful time on a developer-facing platform, API, or infrastructure product. You have shipped something engineers chose to build on. • Technical depth. You read API diffs, write your own queries, prototype against your own endpoints, and hold your own in an architecture review. You don't need to have been an engineer; you do need engineers to take you seriously. • 0-to-1 instincts. You have taken a product from a blank page to real usage in an ambiguous market, and you're comfortable with a roadmap that changes because the ground moved. • Payments or fintech fluency, or the obvious appetite to acquire it fast. Authorization flows, issuing, interchange, chargebacks, settlement, KYC/KYB - you know these, or you'll learn them in weeks rather than quarters. • Judgment under risk. Every control you design trades capability against loss. You can reason about that tradeoff explicitly and defend where you landed. • Strong writing. At Rain, specs, docs, and launch narratives are the job, not overhead. • Bias for motion. You would rather ship a narrow thing this month and learn from it than scope a broad thing for two quarters. Bonus attributes • Hands-on experience building or deploying AI agents - tool use, orchestration frameworks, MCP, evals. • Stablecoin or onchain payments background: settlement, custody, treasury operations, or wallet infrastructure. • Experience working directly with card networks, issuing processors, or sponsor banks. • Time at an early-stage company during a period of fast scaling. THINGS THAT ENABLE A FULFILLING, HEALTHY AND HAPPY EXPERIENCE AT RAIN: Unlimited time off 🌴 Unlimited vacation can be daunting, so we require Rainmakers to take 10 days minimum for themselves.

Location: US Remote; New England; Atlanta; North Carolina; New York; Boston; Florida Cyberhaven is looking for a Chief of Staff for Engineering to collaborate and perform as an operating partner and force multiplier for engineering leadership, driving operating cadence, cross-organizational execution, and data-driven decision making across the entire engineering org. This role is accountable for turning strategic priorities into clear execution plans, and for giving leadership the visibility, metrics, and follow-through they need to run engineering like a well-oiled machine. This is a hybrid role that blends program management, project management, and executive operations: the person in this role will sit close to engineering leadership, represent their priorities across the org, and be the connective tissue between strategy and day-to-day execution. Influence and impact come from judgment, trust, and cross-functional credibility rather than direct authority. This role also serves as the primary architect of engineering leadership's monthly and quarterly business reviews, all-hands content, org planning, and leadership offsites providing decision support, surfacing risk, and driving follow-through on the company's highest-priority engineering initiatives.
