These systems power trusted identity flows across multiple geographies and regulatory environments.
What You’ll Do
- Lead the design, build, and evolution of fullstack applications using React (TypeScript), Kotlin, Python, and Ruby.
- Architect and develop scalable APIs and microservices deployed on AWS, Azure, or GCP.
- Take ownership of complex features from design through to production and ongoing operation.
- Drive architectural discussions and contribute to long-term technical strategy.
- Collaborate with cross-functional teams to deliver secure, privacy-compliant features aligned with regulations (e.g., GDPR, BIPA, CCPA).
- Mentor engineers through code reviews, pairing, and technical guidance.
- Improve system reliability, scalability, observability, and performance.
- Partner with product and UX teams to deliver high-quality, user-centric experiences.
- Champion secure coding practices and contribute to identity and cryptographic systems.
- Identify and implement improvements to engineering practices, tools, and workflows.
Key Projects You’ll Support
- Leading enhancements across identity verification and authentication products.
- Driving the evolution of the Signals platform architecture.
- Designing and maintaining SDKs and APIs for a consistent developer experience.
