Senior Python Engineer (Head of Engineering) at a Techstars startup.

at Aire in London

Aire is a TechStars company in London.

We are a FinTech startup looking to re-invent credit scoring for individuals. Using methods of machine-learning and statistical modelling, we are deriving a new way of credit scoring for consumers that is open, fair and transparent.

  • Looking for a Python engineer with 5 years+ of experience. We already have two other Python team members, so this is a Head of the Engineering role.
  • Getting involved in other functions of the company — we aren’t very big, so we love people ready to roll up their sleeves and help out where they see an issue. Looking at security, scalable architecture and data storage et al.
  • You will also be working directly with our Data Science algorithm team. If you understand R.Py – that is a bonus, as our current algorithm is done in R. Including looking at NoSQL (eg: MongoDB solutions)

Competitive Salary + Bonus + Options + Fun Times


  • Understanding of statistical functions within Python data ecosystem (NumPy, SciPy), and if you know R (or R.Py) that is a great plus
  • Experience with MongoDB. (But if you know other NoSQL DBs like Voldemort, Apache Cassandra – that’s cool too)
  • Personal interest in FinTech and perhaps even credit scoring


  • We just want to learn about your personality, attitude and background.
  • We hope to learn something from you: expertise about a new technology; insight into a trend; a novel approach to solving a problem—something we don’t know yet. What’s your potential? What can you bring that no one else can? What open source projects can you share with us?
  • In the final stage, you will be expected to produce and debug code in an unfamiliar codebase.
  • Immediate feedback from your interviews. We don’t like to keep people waiting.


  • Our team has serial entrepreneurs who understand the importance of people & team. It is always our top priority.
  • Much like in our prior startups, we take care of our people really well. We know it is hard work, but make sure it is rewarding for you too.
  • We are open about people wanting to get involved in other parts of the company – if you can contribute meaningfully, get involved.
  • And obviously we all love Friday Beer O’clocks, team events and the bake-offs. Creative ideas are welcomed.
  • Friends for life

Please note, we cannot sponsor any visas.

Imagine you have the opportunity to work on technology that actually solves real problems of real people. We are consumer-centric in our vision of Aire. Learn more at:
