Techstars - Senior Full Stack Engineer
Requirements
• Strong TypeScript and Python, and the judgment to know when to reach for each • Solid React experience — you can build clean, functional UIs without a dedicated frontend team carrying you • Proficiency with relational databases: data modeling, migrations, and query performance under real load. We use PostgreSQL • Experience building data pipelines end to end — ingestion, transformation, and delivery to downstream consumers. We use event streaming, but experience with any comparable system transfers • Experience shipping LLM-backed features to production: retrieval, embeddings, and the evaluation loop that keeps quality honest. You understand the hard part is uncertainty, evidence, and recovery — not the API call • Comfortable operating containerized services in a major cloud with infrastructure defined as code. We run on GCP and AWS • A track record of owning features from zero to production, and of retiring old systems without breaking things downstream • Strong written communication and a high tolerance for autonomy — remote-first means writing well and staying aligned without being chased • Event-driven architectures and Kafka-based data platforms • Evaluation and observability for LLM features — you've had to answer "is this actually working?" with data • MCP or other tool surfaces that let agents act on production systems safely • Identity and auth systems (Keycloak or similar) • Search infrastructure (OpenSearch or similar) • Next.js and Material UI • Financial or investment data — venture capital, startup portfolio management • Prior work at an accelerator, investment firm, or high-growth startup
Responsibilities
• Own features on Techstars OS end to end — design, build, test, and ship, from data ingestion and API layers through to the web app • Build AI-native features into the product: semantic and federated search across the network, retrieval over portfolio and founder data, and assistive workflows that surface the right context at the right moment • Lead the migration and shutdown of legacy founder tools — including Techstars Universe and our application management system — consolidating functionality into OS or retiring it cleanly • Work across our Enterprise Data Platform and OS to build the pipelines that feed real-time features, search, and AI use cases • Raise the floor on reliability and velocity: tests, code review, and CI/CD practices that hold up as the team grows — including how we fold AI coding tools into that loop • Act as a technical resource for the team — unblock others, weigh in on architecture, and keep context moving across time zones
Benefits
• E-Verify Participation Poster (English and Spanish) • Right To Work Poster (English and Spanish) • Colorado Residents
