Dive deep into hard problems across performance, data modeling, stability, and APIs. Partner with platform, applied AI, and fullstack teams to land robust, observable systems. Improve system reliability and developer experience through tooling, standards, and architecture. What we are looking for: 6+ years in software engineering with strong evidence of owning complex systems. Deep proficiency in Node.js (clean backend architecture is key). Strong relational database fundamentals (PostgreSQL) and experience designing data models. Exceptional debugging skills and strong engineering judgment. Fast learner with the ability to ramp into new domains independently. Nice to have: Experience with distributed systems, caching, messaging, or multi-tenant architectures. Experience integrating AI/LLM capabilities into backend systems. Infra or platform experience (observability, CI/CD tooling, APIs). Why join us? Real ownership from day one. Drive decisions, shape ideas and make them work. Your fastest learning years. Build alongside founders and VPs in a space that moves weekly.
