About WorkOS 🚀
WorkOS builds modern developer tools and APIs that make it easy for companies to become Enterprise Ready. Our platform powers authentication, identity, authorization, and other critical infrastructure that developers need to securely scale their products to large organizations.
We recently raised a $100M Series C, valuing the company at $2B, led by Meritech and Sapphire with participation from Greenoaks, Craft, Abstract, and Audacious. WorkOS powers enterprise features for many of the fastest-growing AI companies, including OpenAI, Cursor, and Perplexity, Sierra, and Plaid.
As AI reshapes software, WorkOS is at the frontier of Human and Agent Authentication, Identity, and Access Control helping companies answer a new critical question: who are your agents, and what are they allowed to do? Our fast-growing customer base includes hundreds of modern software companies building the next generation of enterprise-ready products.
ABOUT THE ROLE
We’re hiring an experienced Engineering Manager to lead Dashboard, the team helping customers get more value from the WorkOS suite and helping WorkOS grow as a business. We’re looking for a leader who is excited to manage engineers, but approaches the role as a startup founding member would.
You’ll lead engineers working across customer onboarding and growth, billing and monetization, and AI assistance in the WorkOS dashboard. The team’s work connects the customer journey from signup and integration through production and expansion. You’ll partner closely with design, go-to-market, finance, and other engineering teams to make that journey simpler and more effective.
This role offers meaningful autonomy to shape what we build and why. It’s a great fit for a strong product thinker who enjoys working closely with product managers and taking the lead on product decisions when the opportunity calls for it. You’ll have room to identify customer problems, propose new directions, and carry ideas from discovery through launch, with ownership of the outcomes. If you’re excited by the chance to combine engineering leadership with product judgment, there’s a lot to build here.
You’ll also drive technical strategy, empower your team to execute on projects with a direct impact on customer success and the business, and play a pivotal role in scaling the team and recruiting exceptional engineers.
WHAT YOUR TEAM WILL BUILD
- Growth and onboarding: help developers move from signing up to integrating and running WorkOS in production. Improve onboarding and next steps, and work with go-to-market teams on timely outreach informed by product signals.
- Billing and monetization: build annual-credit capabilities, make billing more reliable and automated, and give customers clearer pricing, usage, and credit information in the dashboard.
- AI assistance for developers: bring the Dashboard Agent, WorkOS MCP server, Ask WorkOS, and Support Bot into a coordinated experience, with shared retrieval, evaluations, and quality standards. Help developers get useful, consistent answers and make progress with WorkOS.
RESPONSIBILITIES
- Build and lead a high-velocity team that ships product fast and with polish across growth, monetization, and developer assistance.
- Be deeply technical and hands-on: read the PRs, write prototypes, and work with technical leads on architecture and project scope.
- Shape the roadmap in close partnership with product managers, design, go-to-market, finance, and engineering. Bring your own product perspective, identify opportunities, and drive product decisions directly where needed—from defining the problem and choosing an approach to measuring the outcome.
- Help the team improve the customer journey from signup to production and expansion, using product signals and customer feedback to choose what to build next.
- Balance rapid product iteration with the reliability and correctness customers need from billing and the quality they expect from AI assistance.
- Push for clarity, focus, and high energy in every sprint. Drive urgency without burning people out.
- Spend time with customers and engineers alike—digging into pain points, testing assumptions, and improving the craft.
- Coach, mentor, and grow a team of curious, driven engineers through direct feedback, clear goals, and meaningful ownership.
- Partner with recruiting to attract, hire, and retain exceptional engineering talent.
QUALIFICATIONS
- Track record of having successfully led product-focused engineering teams in high-performing organizations that shipped real impact.
- You've written code at a high level, and you still love to get your hands dirty. You view leadership as an amplifier, not a step back.
- Bias for action and scrappiness: You don’t over-optimize for process. You optimize for velocity, customer value, and learning.
- You deeply care about the developer experience. You think about UX, APIs, performance, edge cases, and joy.
- You ask "why" obsessively, and you push yourself (and your team) to learn constantly.
- You build trust, give direct feedback, and create space for engineers to thrive.
- You have experience partnering with internal recruiting teams to drive effective and fair hiring processes. You realize that recruiting is a large and important part of your role, and have a track record of recruiting, hiring, and mentoring top engineering talent.
- You’re a strong product thinker who connects customer needs, technical possibilities, and business outcomes. You collaborate well with product managers and are comfortable driving product decisions yourself, using customer insight and evidence to make tradeoffs and build alignment.
Experience with onboarding and growth, billing systems, or customer-facing AI products is especially relevant. You do not need prior experience in all three areas.

About Anthropic
Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.
About the role:
Large teams of agents are starting to solve problems no single agent can, from rewriting major codebases to formalizing landmark mathematics. Our team studies how these teams scale: what happens to performance, cost and coordination as the number of agents, the compute budget and the length of the task grow, and what has to change to keep getting returns from that scale. We build the platform and evaluations Anthropic uses to run and measure large agent teams, and other research teams build on them.
This role lives at the boundary between research and engineering. It is a generalist role on a small team: you'll design and run large experiments, build the systems they run on, and get to the bottom of surprising results. We often need to go from a vague question to a running experiment quickly.
Responsibilities:
Design, run and interpret large-scale experiments on agent teams, reasoning rigorously about what the data does and doesn't show
Investigate how performance and efficiency change as team size, compute and task horizon grow, and find the bottlenecks that limit them
Build and scale the systems that run very large agent teams reliably, and debug the failures that only appear at scale
Design evaluations for long-horizon problems, and keep their results trustworthy
Build the tooling and metrics that let researchers see what a large agent team is doing and why
Partner with research teams across Anthropic so they can run their own experiments on the platform, and communicate findings clearly
You may be a good fit if you:
Have significant software engineering, ML or research engineering experience
Have owned something substantial end to end, such as a large system, an evaluation or benchmark, an agent product, or a research project
Genuinely enjoy both research and engineering work
Think quantitatively about complex systems, and think twice before trusting a number
Can work from a vague question rather than a spec
Are results-oriented, with a bias towards flexibility and impact
Have clear written and verbal communication
Care about the societal impacts of your work
Strong candidates may also have:
Experience building or operating large-scale distributed systems, such as schedulers, sandboxed code execution, or inference and RL infrastructure
Built evaluations, benchmarks or harnesses for LLMs or agents
Experience building complex agentic systems that use LLMs
Experience with scaling laws or other large-scale empirical research
A background in operations research, statistics, economics, physics, quantitative finance, or another field that models and optimizes complex systems
Strong candidates need not have:
Formal certifications or education credentials
Academic research experience or publication history
Prior experience with multi-agent systems or reinforcement learning
Representative projects:
Measure how performance scales with the number of agents on a hard problem, and explain where the curve bends and why
Prepare our largest-ever agent run: find what breaks as team size and task length grow together, and fix it before launch
Work out how to allocate a fixed compute budget across a team of agents to solve a problem fastest
Build tooling that turns the activity of a large agent team into something a researcher can read in minutes
Design a novel eval that distinguishes real gains in teamwork from artifacts of the evaluation setup
The annual compensation range for this role is listed below.
For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role.

Years of experience required will correlate with the internal job level requirements for the position
Location-based hybrid policy:
Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.
Visa sponsorship:
We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.
We encourage you to apply even if you do not believe you meet every single qualification.
Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.
Your safety matters to us.
To protect yourself from potential scams, remember that Anthropic recruiters only contact you from @anthropic.com email addresses. In some cases, we may partner with vetted recruiting agencies who will identify themselves as working on behalf of Anthropic. Be cautious of emails from other domains. Legitimate Anthropic recruiters will never ask for money, fees, or banking information before your first day. If you're ever unsure about a communication, don't click any links—visit
anthropic.com/careers
directly for confirmed position openings.
How we're different
We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.
The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
Come work with us!
Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
