Software Engineer

This is a hybrid position requiring in-office attendance two days per week at our Atlanta office. Candidates must reside within a commutable distance to be considered.

• This is a ground-floor opportunity to join a small, agile team operating in "startup mode" with the resources of a market leader. Your mission: build the products that will define how the next generation of software engineers develops, debugs, and deploys AI agents.

• As a Software Engineer on this team, you will design and build the full-stack systems that give AI developers superpowers. This isn't about just building a UI; it's about inventing the entire interactive experience for a deeply technical user. If you have a strong CS foundation, a hunger to tackle ambiguous problems, and a demonstrated passion for building with AI, we want to talk to you.

• At Fullstory, we capture a perfectly preserved digital reality. Our engine processes petabytes of high-fidelity, structured event data from every click, tap, and interaction across the web. Now, we're building a new team to tackle one of the most exciting challenges in tech: turning this unparalleled dataset into the essential toolkit for AI builders.

In a typical day, you might:

• Build and ship full-stack features, writing clean code from our Go back end to our React front end, and further into our AI oriented APIs. Expect 60-80% focused on the front end and API side, 20-40% on back end code.

• Own your work from the initial design session all the way through to production deployment and support.

• Collaborate with senior engineers daily through pair programming, architectural white-boarding, and detailed code reviews.

• Explore the cutting edge of AI by building rapid proofs-of-concept with the latest tools and research

Here’s what we’re looking for:

• You have experience with modern front-end technologies like React and TypeScript and have experience building user interfaces from the ground up, whether in a professional environment, for an internship, a personal project, or complex coursework.

• You have experience writing clean, well-structured, and testable code in a language like Go, Java, or Python, and you understand the principles of building robust server-side applications.

• You have experience using AI agents to quickly bring product ideas to life by creating solid, tested, scalable, and understandable code.

• You have a solid grasp of data structures, algorithms, and API design from relevant coursework. You can reason about the trade-offs in transforming data under constraints for use by AI Agents with a limited context window and strict latency and cost requirements.

• You are deeply curious about how modern AI systems are built. You can thoughtfully discuss the latest developments (e.g., from papers, blogs, or your own projects) and have a genuine interest in building the next generation of developer tools.
