Staff Software Engineer, Internal Tools

Qualifications

• 8+ years of software engineering experience, with demonstrated ability to own and deliver complex systems end-to-end — from design through production operation.
• Deep expertise in distributed systems design, fault tolerance, and building reliable systems from unreliable components.
• Strong full-stack engineering fundamentals. Our stack: Node.js/TypeScript (backend, Express), React/TypeScript (frontend), PostgreSQL with Drizzle ORM, Python for ML pipeline components, OpenAI and Google Gemini APIs.
• Demonstrated bias toward shipping. Track record of turning ambiguous problems into working systems on a reasonable timeline — not just designs or proposals.
• Good technical judgment under uncertainty. Pragmatic trade-offs, knowing when "good enough" is right, and not over-engineering when the problem doesn't call for it.
• Experience designing systems that handle non-deterministic or probabilistic outputs (ML models, LLM pipelines, or similar) with appropriate confidence scoring and fallback strategies.
• Familiarity with LLM application patterns: prompt engineering, multi-model orchestration, agentic tool use, and cost optimization for high-volume LLM workloads.
• Experience with document AI or structured data extraction from unstructured sources (documents, image, natural language) at scale.
• Background in ad tech, revenue operations, or media operations — order management, pricing logic, deal lifecycle.
• Experience building over heterogeneous enterprise data sources with varying freshness, schemas, and access patterns.
