Backend engineer building scalable AI - native cybersecurity infrastructure for Doppel. Developing software that detects and disrupts phishing, impersonation, fraud, and other digital threats.
About the role
- Software Engineer shipping full-stack features for Bree's financial services platform. Collaborating across TypeScript and Node serverless stack, enhancing app delivery and customer impact.
Responsibilities
- Ship full-stack features end-to-end: product discovery, scoping, implementation, and release.
- Work across a TypeScript/Node serverless stack (AWS Lambda, API Gateway, SQS) and React Native frontends.
- Make pragmatic calls in ambiguous situations; unblock yourself and others without waiting on perfect specs.
- Instrument what you ship (logging, metrics, alerts) and add tests to keep releases stable.
- Improve existing surfaces: refactor opportunistically, pay down tech debt without slowing delivery.
- Collaborate tightly with design and product on customer-visible outcomes, not theoretical elegance.
Requirements
- Have real startup experience shipping product in lean environments.
- Have shipped things personally (side projects, OSS, indie apps) and can show a portfolio/GitHub.
- Are fluent in TypeScript and comfortable across Node, React/React Native, and REST/GraphQL APIs.
- Have worked with AWS serverless (Lambda/SQS) or equivalent event-driven systems.
- Use testing pragmatically (Jest, React Native Testing Library, Detox) and integrate into CI.
- Demonstrate product judgment: you can refine a rough idea into a scoped, high-leverage release.
- Communicate clearly, default to ownership, and stay even-keeled when wrestling with engineering tradeoffs.
Benefits
- $250 monthly lunch stipend
- $150 monthly commuter stipend
