Founding Software Engineer

About us

At Stackfix, we’re transforming how software is bought and sold. Our product is a Software Marketplace that enables businesses to discover, buy and implement software incredibly quickly. Under the hood we’re building an AI system that can automatically test and use the products on our marketplace, giving our customers unrivalled data and capabilities.

We’re repeat founders on a mission to create a category defining company, and are backed by some of Europe’s top VC funds and angels. If you want to take a product from 0 to 1, and work closely with LLMs/agentic systems, then please get in touch.

About the role

We’re seeking an entrepreneurial engineerwho will work closely with the founders to build and scale Stackfix’s software marketplace.

This is full-stack, product engineering role with the additional ownership that comes with being our 3rd engineer. You'll play a fundamental role in shaping both the product and Stackfix as a company.

Who you are

• You are first and foremost a builder. You have a track record of shipping products in a fast-paced environment.

• You are driven by building fantastic product experiences - if something's not right in the product, it nags you.

• You are fascinated by LLMs and are excited to build on top of them (but you don't need to have any prior LLM experience).

• You are truly full-stack. You are equally comfortable working on client facing applications and back-office data processing jobs, as well as architecting and maintaining cloud infrastructure.

• You thrive in a startup environment. You’re excited by the idea of speaking with customers in the morning and shipping features to solve their problems in the afternoon. You’re ok with priorities changing and you’re comfortable with risk.

• You value working with people who are low ego, ambitious and pragmatic

• You are comfortable figuring out how to build things you haven't built before.

• You’re an excellent communicator. Both written and verbally.

• You ideally have experience with most of the following: Typescript, Python, Vercel, AWS, React (Next.js), Docker, MySQL (Planetscale).

• You are excited to work in-person from our office in London 4 days a week.

Some topics you’ll think about

• Building performant, beautiful, and reliable software that our users trust, and enjoy using. Our competitors have UX that sucks, ours should delight.

• Making software comparison and purchase more personalized using LLMs. You’ll be selecting models, chaining prompts, and understanding how to build a truly differentiated UX.

• Designing real-time interactions: features like dynamic product display, personalized pricing, and multiplayer editing that will unlock a 10x better experience for our customers.

• Architecting a new protocol for software comparison and purchase. This is a fast moving and complex domain - you’ll be figuring out the primitives on which software commerce is built.
