Member of Technical Staff, AI Engineer

About Testudo

Testudo is a Lloyd's of London Coverholder building the risk infrastructure to insure the AI economy. We write generative AI liability insurance with the backing of four Lloyd's syndicates, alongside the real-time risk monitoring technology behind it, so that companies can deploy AI and agents confidently.

We are a strong team operating across New York and London. This role is in New York.

Our mission: to insure the AI economy.

About the Role

As aMember of Technical Staff, AI at Testudo, you'll build the core services of our underwriting and risk monitoring platforms — the systems that decide what we insure, what we charge, and what we watch after the policy is bound.

You'll be among the first engineering hires outside the founding team, with end-to-end ownership of features, real product input, direct access to customers, and the mandate to move fast. The systems you own will manage billions of dollars of real financial risk capital.

Representative projects

• Owning services end to end, from the Python and Postgres data layer, through the Node.js/TypeScript API, to the Next.js surface that exposes it.

• Building the backend services behind underwriting pipelines and real-time monitoring dashboards.

• Integrating LLM and agentic workflows into production, with the evals and observability to know when they are wrong.

• Operating 5-10+ coding agents in parallel, and building the tooling that makes that work.

• Leading system design for scalability and robustness in a domain that changes underneath you.

• Turning ambiguous problems from founders, risk, and data science into shipped software.

You may be a good fit if you

• Have 5+ years building production web software, ideally at a startup.

• Are fluent in Python and Node.js/TypeScript, with real front-end and design experience in React/Next.js.

• Have designed scalable services, built high-throughput data pipelines, or handled real-time monitoring.

• Operate with ownership and autonomy; you bias toward action and unblock yourself.

• Communicate well across product, risk, data science, and customer contexts.

• Relish direct feedback and want to work in person, at pace.

• Have shipped LLM or agentic features to production, and built the evals and observability that tell you when they are wrong.

You may not be a good fit if you

• Need the architecture settled before you start building. This domain changes underneath you and the systems have to survive it.

• Want heavy process and long planning cycles over a ship-daily culture.

• Would rather own one layer deeply than the whole path from data pipeline to dashboard.

• Are uncomfortable trusting an agent with real work, or reviewing its output at volume.

• Prefer remote or hybrid. We are in the office five days a week, and we work long days.

Our stack

Next.js/TypeScript on the front end. Node.js and Python on the back end. Python, SQLAlchemy, Postgres and Temporal for data and infrastructure. CI/CD, AI dev tools, and evals/observability pipelines throughout.

Compensation & Location

• $150,000 - $250,000 base + meaningful equity.

• We run a single band across every role at this level. We would rather pay the same for different kinds of hard problem than pretend we can rank them.

• New York. In-office, five days a week.

• We are able to sponsor visas for this role. Relocation support available.

• Health insurance.
