THE OPPORTUNITYWe are building Watcher, a 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 multinational enterprises. We are now hiring our first dedicated Engineering Manager to lead the product engineering team.
We are looking for a strong hand-on engineer who still ships code, and can own both the people management and the execution of the product engineering team. This is a player-coach role. Today, you will spend most of your time managing and coordinating, but still ship code. As the team grows, you'll transition towards 100% leadership and management.
The team is small today and is growing fast, so you will have significant say in shaping the team, the process, and the product, and your scope will grow with the team. You will report directly to Marius (CEO), who will own Watcher's product direction and roadmap.
KEY RESPONSIBILITIESExecution and delivery management (~40%)- Own the team's planning and tracking. Turn goals and customer commitments into concrete, well-scoped tickets with clear owners. Everyone on the team should always know what they're supposed to be doing and whether we're on track.
- Run the operating rhythm (planning, standups or async equivalents, retros).
- Track dependencies between product engineering, monitoring research, and infrastructure/security work, and proactively resolve conflicts.
- Translate between researchers and product engineers. Turn research outputs (new monitors, backtesting results) into scoped, prioritized engineering work.
- Track customer commitments (integration timelines, requested features, incident follow-ups) and coordinate releases, testing, documentation, and customer communication.
- Surface risks and slippage early, and proactively give Marius (CEO) an accurate, always-current picture of status.
People management (~30%)- Directly manage the product engineers. Run regular 1on1s, give direct and actionable feedback, and own their growth, performance, and wellbeing.
- Own performance management end to end. Set clear expectations, recognize strong work, and address underperformance early and honestly.
- Drive hiring for the team. Own the pipeline together with ops, run interview loops, close candidates, and onboard new engineers so they ship in their first weeks.
- Protect the team's focus. Shield engineers from thrash, keep meetings minimal, and make sure priorities are stable enough to execute against.
Hands-on engineering (~30%)- Ship code yourself. Features, bug fixes, internal tooling, and prototypes, primarily in Python and TypeScript. Staying hands-on keeps your technical judgment current and your tickets realistic.
- Set the technical bar, make architecture decisions, review code and establish norms, and release and incident processes.
- Build tooling that makes the team faster, including AI-assisted tooling for your own job (status reporting, ticket triage, ramp-up docs). We expect you to leverage AI heavily when reasonable across both management and engineering work.
REPRESENTATIVE PROJECTS- Lead the team within 90 days. For the first few weeks, you will work closely with all engineers to understand their priorities, all of our ways of working, and procedures. Then, we ramp up responsibilities and you start to scope out proposals and get rapid and detailed feedback. Once you have onboarded properly, you will start running the meetings, etc.
- Deliver a major customer integration. Scope a large enterprise deployment with the team, turn it into tickets, sequence it against other priorities, track progress against the customer's timeline, and ship code on the critical path yourself where needed.
- Scale the team. Scope the hiring needs for the next 2-3 product engineers, drive the process end to end, while keeping the existing team shipping. Ensure hiring is done to a high standard and is fast.
- Bridge a research handoff. Take a new monitoring capability from the research team, work with researchers and engineers to turn it into a scoped production plan, and manage its delivery into Watcher including rollout, documentation, and customer-facing changes
JOB REQUIREMENTSMust-haves- Strong engineering background. You worked as a software engineer for at least 4 years before managing. You still ship production code today. You will be judged partly on code you write in this role, primarily in Python and/or TypeScript.
- People management experience. You have hired, onboarded and managed small teams of engineers directly (1on1s, feedback, performance,), or you have been a tech lead who de facto did this for at least 2 years. You can point to engineers who grew or shipped better because of you.
- Execution ownership. You have run delivery for a multi-person engineering effort, turning goals into tickets, tracking them to completion, and being accountable for the outcome.
- High agency. You see what the team needs and do it without being asked, whether that's fixing a process, having a hard conversation, or shipping the fix yourself.
- Direct communication. You give and take blunt feedback, address problems with people early and kindly, and say clearly when something is off track, including to the CEO.
- Startup pace. You are excited about a fast-moving environment, comfortable with ambiguity and changing priorities, and willing to grind when it matters.
- Comfortable leveraging AI heavily for management, coordination, and coding work, while holding the output to a high standard. You have used Claude Code, Codex, Cursor, or similar tools heavily.
Strong nice-to-haves- Experience coordinating between research and engineering, or shipping products with an ML/research component.
- Customer-facing delivery experience, e.g. enterprise integrations, deployment projects, or technical account work.
Explicitly not required- Formal AI safety background. We need excellent engineering leaders who can learn the AI safety context.
- Large-team management experience. This is a small, senior team. Managing 30 people at a big company is neither necessary nor necessarily good preparation.
- Certifications (PMP, scrum, etc.). We care about demonstrated ability, not credentials. If your instinct is the heavyweight process, this is the wrong team.
BENEFITS- This role offers market competitive salary, equity, and competitive benefits.
- Salary: San Francisco: $283,000 - $396,000; London: £190,000 - £266,000
- Our engineers effectively have an unlimited token budget. If a better result costs more compute, use it.
- Flexible work hours and schedule
- Unlimited vacation
- Unlimited sick leave
- Up to 6 months of paid parental leave
- Comprehensive health, dental and vision insurance
- Retirement savings with competitive employer matching (e.g. 401(k) for US employees)
- Lunch, dinner, and snacks are provided for all employees on workdays
- Paid work trips, including staff retreats, business trips, and relevant conferences
- A yearly $1,000 (USD) professional development budget
- Relocation support and visa fees (if applicable)
LOGISTICS- Time Allocation: Full-time
- Location: This is an in-person role working out of our London or San Francisco office. We offer flexible working hours and some wfh arrangements.
- Visa sponsorship: We sponsor visas in both the UK and US. Sponsorship isn't guaranteed for every role or candidate, but if we make you an offer, we'll work with you to find the right visa route.
ABOUT THE TEAMThe product team consists of product engineers: Jeremy Neiman, Zak Walters, Zen van Riel, Srdjan Miletic and Gustavo Bicalho; research scientists: Victor Gillioz, Monika Jotautaitė, Dmitrii Volkov; and our GTM lead: Kyle Dai. Marius Hobbhahn (CEO) advises the team. Furthermore you will interact with our other SWEs and researchers, since we intend to be "our own customer" by using our products internally for our research work. You can find our full team here.
HOW TO APPLYPlease 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. 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.
