About the role

A security & control expert embedded in the product team with three functions:
Expert view: Bring a security expert's view of what security buyers need to make Watcher a better product (~25%),
The Product / Control team is a new team.

Security support for research (50%)
Develop threat models for coding agents under the assumption that they could be misaligned or compromised. This includes near-term threats like AI agents leaking private internal data and long-term threats like agents sabotaging safety research.
Build and maintain our "coding agent security levels" which define what level of robustness Watcher provides against different categories of failure modes.
Maintain our library of coding agent failure modes and keep it comprehensive, accurate, and current.
Attack design for monitor development
Design realistic attack trajectories and example exploits for monitor development and backtesting, work with the research team to ensure monitors are trained and evaluated against credible adversarial behavior.
Relocation support and visa fees (if applicable)

5+ years in security roles in a hands-on technical capacity (not purely GRC/compliance).
This is truly a "start-up role" in the sense that you have many responsibilities and have significant say in shaping the direction of the role.

Direct experience with application security, cloud security, or product security.
Ideally has owned or significantly contributed to the security posture of a product that handles sensitive customer data.
Strong understanding of enterprise security buyer concerns.
Ideally has been a security engineer or senior security leader at an organization that buys security tooling, or has worked closely enough with those buyers to internalize their priorities.
Comfortable working in a small, fast-moving team where they'll need to context-switch between hands-on security work and strategic product thinking within the same week.
Strong written communication.
This role produces a lot of artifacts (threat models, security levels, questionnaire responses, failure mode documentation) and they need to be clear and precise.
Experience with AI/ML systems security, LLM security, or AI control research.

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)
Salary: 135k - 200k GBP (~180k - 270k USD)

This role offers market competitive salary, equity, and competitive benefits.
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)

Especially early on, you will work closely with Marius Hobbhahn (CEO & currently leads the monitoring team), Victor Gillioz (Research Scientist), Monika Jotautaitė (Research
Jeremy Neiman, Zak Walters, Zen van Riel, and Srdjan Miletic.
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.
We are building Watcher, a coding agent security product.
These levels should be concrete, testable, and usable both internally (to guide product priorities) and externally (to communicate our security posture to customers).

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.
