Senior Backend Engineer

service Design schemas and evolve data models (SQLAlchemy/SQLModel-style ORM plus migrations) that support both traditional application logic and AI-driven features Instrument services with structured logs, distributed tracing, and cost/latency metrics, holding a real bar for p95 response time under production load Maintain end-to-end CI/CD ownership, lint, type-check, test, package, and deploy, so releases are boring and safe Champion AI across the delivery lifecycle, not just code generation, and set the guardrails the team works inside: how generated code gets reviewed, how provenance and licensing are checked, and what customer data may enter a prompt Move ideas from concept to production fast, with real ownership over architecture and outcomes, not just tickets Who You Are & What You'll Need to Succeed 5+ years building production backend systems in Python, with real async I/O experience Hands-on experience designing and scaling REST or async APIs, including dependency injection and clean service architecture Practical experience integrating LLM APIs (Open AI, Gemini, or similar) and building AI-readiness into backend systems from the ground up Real experience with vector databases and RAG-style retrieval architectures, not just reading about them Strong relational database skills: schema design, query optimization, and migration discipline AI-augmented delivery: you use AI across the delivery lifecycle, not just code generation, and can say which models suit which problems and where you don't use them. You review AI-generated code knowing its failure modes, and you have set the guardrails others work inside — review expectations for generated code, provenance and licensing checks, and clear boundaries for what customer data enters a prompt and what a security or compliance review will ask for. End-to-end CI/CD ownership, from build and test through packaging and deployment A self-starting, go-getter mindset: comfortable with ambiguity, fast iteration, and owning a problem until it's actually solved Bonus: experience with multi-agent orchestration frameworks (Semantic Kernel, Lang Chain, or similar) and LLM cost/observability tooling Why You'll Love Us We’ve evolved: We provide three work environment scenarios.
