Company mission
To invest in an unprecedented number of startups per year to enable more capital to flow to more entrepreneurs around the world in order to deliver exceptional returns to our investors.
Role
Who you are
- 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
Desirable
- 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
What the job involves
- Techstars is building an operating system that centralizes how we run accelerator programs, support founders, engage the network, and drive investment decisions
- As a Senior Full Stack Engineer you'll own features end to end — from the data behind them to the React UI in front of them, from design to go-live
- That includes the AI-native parts of the product: search that spans the network, retrieval over founder and portfolio data, and assistive workflows that put the right context in front of the right person
- You'll also lead the wind-down of our legacy founder tools, consolidating what matters into OS and retiring the rest cleanly
- This is a small, high-trust team. We move fast, ship real things, and expect everyone to be able to hold a thread all the way through
- 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
Our take
Techstars runs a startup acceleration program that guides aspiring entrepreneurs in launching their startups successfully. Each year, Techstars selects a number of early-stage companies to participate in a 3-month accelerator programme, which includes $120K in funding, mentorship, and financial support.
In response to the rapid pace of technological innovation, generating numerous new ideas, Techstar recognises the potential of many promising concepts going unnoticed. By investing both financially and inspirationally in startups, Techstars aims to not only support these ventures but also generate significant returns through equity investments.
Due to funding difficulties, Techstars decided to close several of its European accelerator programmes in 2026, shifting its focus from quantity to quality. It still runs out of New York, Amsterdam and London, and despite global funding challenges, maintains its reputation as a leader in startup acceleration.
