What You’ll Do
- Build and evolve our detection platform.
- Working closely with our founding team, you'll help design and build the systems that identify account compromise in real time — spanning signal ingestion, behavioral analysis, and AI-powered decisioning.
- Drive product quality end to end.
- Take problems from raw customer insight through to shipped, production features.
- Architect for scale.
- Raise the technical bar.
Who You Are
- 3+ years of software engineering experience, with meaningful time in production systems at scale.
- Deep full-stack fluency — comfortable owning a feature from data model to UI, with strong opinions about where to draw the lines.
- Experience building data-intensive or real-time systems.
- Bonus if you've worked on security, fraud detection, or anomaly detection pipelines.
- Strong ML/AI integration experience — you've shipped systems that use models in production, not just experimented with them.
- High agency and high output. You don't wait for a spec — you identify the problem, propose the solution, and execute.
- Sharp and scrappy. You learn fast, ask the right questions, and figure it out — whether that's a technical tradeoff, the right abstraction, or the right shortcut.
- Comfortable in a small-team, high-autonomy environment.
- Proud of your craft. You care about building things that work well and hold up over time.
