The role

Help build and extend Our backend roadmap, turning identity, device and session signals into trust scores, actions and transparent reasons, with guidance from senior engineers.

Day-to-day work

- Build API endpoints and validate incoming device, identity and session events; handle missing or malformed fields and keep signal records consistent for downstream scoring. Follow contracts agreed with senior engineers.
- Implement and test guided fraud rules, such as new-device checks and unusual activity velocity; return reason codes that explain why a rule affected the decision.
- Extend signed SDK and business APIs with senior guidance, adding request validation and access checks while keeping each customer's data isolated across requests and sessions.
- Reproduce SDK integration errors using sample requests, logs and metrics; work with SDK engineers to resolve event-format mismatches and document the expected API behaviour.
- Write unit tests for valid,



invalid and boundary cases, participate in code reviews, and follow fixes through testing and release monitoring with the team.

What you bring

- Working knowledge of Python, Go or Rust, plus HTTP, REST, JSON and basic SQL.
- Data structures and algorithms fundamentals, with readable code and practical debugging skills.
- Comfort with Git, Linux and learning through feedback in code reviews.
- Interest in security and fraud prevention; curiosity about how attackers abuse systems.
- Proficiency with agentic AI coding tools, with the ability to review, test and take ownership of generated code.

Good to have

Exposure to PostgreSQL, Redis, queues, Docker or request signing; a backend project, open-source contribution or CTF experience you can explain.
