About Stackfix

About the role

We’re seeking an entrepreneurial engineer who will work closely with the founders to build and scale Stackfix’s software marketplace.
This is backend focused, product and data engineering role with the additional ownership that comes with being responsible for owning the data pipeline that will power the innovative Stackfix experience. 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 have some experience building agentic systems using LLMs or RL techniques, recommendation systems, and/or Q&A “chatbot” systems using RAG techniques or similar.
You have a bias to productionize. You’re keen to push the results of your experimentation to customers, iteratively and rapidly, in order to solve real-world problems.
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 are experienced with Python and have built large scale, reliable and performant data pipelines in the past.
You have experience with most of the following: AWS, Docker, Pytorch, Langchain, DSPy, MySQL (Planetscale).
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.
Some topics you’ll think about
Designing LLM-powered agents that analyze software products. You’ll be working on the cutting-edge of this domain with support to fully explore what agentic systems are capable of.
Building real-time data transformation pipelines to process diverse, unstructured product data into useful data for our customers.
Defining a new standard for market intelligence. You’ll take ownership over the data products we’re creating to increase the efficiency of the software market.

Our hiring process

We like to move quickly. For that reason, we follow a short, standardised process for all engineering roles. It’s designed to help us learn more about you and crucially, for you to discover if you’d like working with us.
Intro chat with Paddy (CEO). We’ll begin by having an informal discussion about your experiences, values, and career goals, and give you an opportunity to get a sense of the role and the team.
Technical discussion with Camin (CTO). We’ll dig into the things you’ve built and are building, the technical challenges you’ve overcome and discuss how we do engineering at Stackfix. You’ll have the chance to ask questions about our technical strategy, what we’re working on currently, and learn more about the technologies we use.
Paid work trial. The highest-signal thing we can do to learn if there is a mutual fit is to work together. We’ll invite you to our central London office to work with us (paid) for roughly 1/2 day. In some exceptional cases we might ask you to do a remote work assessment instead of an in-office trial. You’ll complete actual project work on your own laptop (not inverting a binary tree on a whiteboard). Feel free to ask questions and pair program, you’re our colleague for the day. We may also chat through a system design problem of actual relevance to Stackfix.
References. At this stage, we ask for references. We believe exceptional people are consistently exceptional, but we also appreciate humility. We want to learn where you’re world-class, where you have room to grow, and how we can provide the best environment for you to excel.
Offer. We’ll make you an offer and look forward to having you join us!
We aim to have this entire process done in less than 2 weeks but understand if scheduling is a challenge, so this isn’t a hard rule. The most important thing is that we both feel confident and excited to work together.
