Senior Full Stack Engineer

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
• Act as a technical resource for the team — unblock others, weigh in on architecture, and keep context moving across time zones

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
• Experience shipping LLM-backed features to production: retrieval, embeddings, and the evaluation loop that keeps quality honest
• 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

Preferred Qualifications

• Event-driven architectures and Kafka-based data platforms
• Evaluation and observability for LLM features
• 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

Benefits

• Medical, dental, and vision insurance
• 401(k) retirement plan
• Paid time off
