Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Full Stack Engineer - **Company:** Techstars LLC - **Location:** Boulder, CO, United States (Remote available) - **Experience:** Expert - **Salary:** $120,000.0 - $150,000.0 - **Contract:** Permanent contract - **Skills:** Query Performance, Application Programming Interfaces (APIs), Artificial Intelligence, Amazon Web Services, Application Lifecycle Management, Code Review, Continuous Integration, Relational Databases, Python (Programming Language), PostgreSQL, Next.js, TypeScript, Web Applications, Enterprise Data Management, Data Ingestion, ReactJS, Large Language Models, Event Driven Architecture, Material UI, Apache Kafka, Data Management, Front End Software Development, Data Pipelines - **Published:** September 12, 2026 - **Apply:** https://www.builtincolorado.com/job/senior-full-stack-engineer/11135921?handler=ApplyRedirect ## About the Role * 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, E-Verify Participation Poster (English and Spanish) ## Description Own full-stack features for Techstars OS from data ingestion and APIs through React interfaces and production delivery. Build AI-native search, retrieval, and assistive workflows using founder and portfolio data. Lead migration and retirement of legacy tools, develop data pipelines, improve testing and CI/CD, and provide architectural guidance. The role requires strong autonomy, written communication, and end-to-end ownership across cloud infrastructure and product development. The summary above was generated by AI 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. What you will do * 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 ## Related Videos - [Build and Deploy a Fullstack App with Open Source Tooling](https://www.wearedevelopers.com/videos/775-build-and-deploy-a-fullstack-app-with-open-source-tooling) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Vuejs and TypeScript- Working Together like Peanut Butter and Jelly](https://www.wearedevelopers.com/videos/127-vuejs-and-typescript-working-together-like-peanut-butter-and-jelly) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift)
