Product Engineer (Full Stack)

We make software for the places people live. Specifically, managed buildings and the people on both sides of them.

Residents and leaseholders get an app: message the people who manage their building, pay their service charge, report maintenance issues and get to know their neighbours. Property managers and the on-site team get a web platform they run the building from: responding to resident queries, handling keys and packages, and staying on top of compliance.

It is software with real stakes. When it works, someone's home runs a little more smoothly, and someone's job gets a lot less painful.

Every property management company in the UK is running on email, spreadsheets and disconnected tools that were never built for the job. We are replacing that. Cortile is becoming the operating layer that property teams and residents cannot imagine working without: a unified platform for communication, compliance, maintenance and payments.

We are a small team with a huge impact. Thousands of people use Cortile every day and we are trusted by some of the largest companies in the sector, including the industry body. The companies we work with manage around 400,000 homes, and we are uniquely positioned to work in partnership with them and use AI to shape the future of property management.

• Whoever is leading the problem does all of it. You will sit on customer calls, work out what is worth building, design it, ship it and check whether it made a difference. If it did not, that is yours to fix too. Worth knowing that a decent chunk of your week will not be spent writing code.
• We are in the office together, 4–5 days a week. This is a deliberate choice. Our best work is done in person: shorter feedback loops, quick decisions, thinking out loud together.
• You drive your own growth, and we back it. We give you real problems with real consequences and point you in the right direction, but the people who do best here go and get good at things rather than wait to be taught.

You will join a small, cross-functional product team working closely with our founders, customer success, growth and product. The roadmap is packed: new technologies to champion, problems that touch people's daily lives, and existing architecture to improve for the whole engineering team.

• Take problems from unclear to shipped. Discover, architect, build, test and deliver new features across the entire stack.
• Build with users, not just for them. Property managers and residents give us direct, sometimes blunt feedback. You will be close enough to hear it first-hand and turn it into product the same week.
• Use AI to do the previously impossible. Turning messy inspection reports into clear action plans, making sense of resident messages, drafting replies a manager can actually trust. The kind of thing that was not buildable a couple of years ago.
• Have a real say in what gets built. Your product instincts matter as much as your code. If you think we are building the wrong thing, we want to hear it.
• Share your expertise. Be on hand to help other team members, technical or otherwise, and help mentor other engineers.
• Help us operate more efficiently by building and maintaining our developer tooling and CI/CD pipelines, and staying at the forefront of the latest AI tools.

The people who thrive here tend to:

• Have a strong bias to action. You spot what is missing and go and do something about it, rather than waiting to be asked.
• Have good product instincts. You have taste for what to build and the discipline to leave the rest out.
• Be comfortable with ambiguity. You can make real progress without a clear spec, and you are happy changing course when the problem turns out to be different than you thought.
• Be kind and low-ego. You are collaborative and pragmatic, you would rather get it right than be right, and you are easy to build alongside.

On the engineering side, you will probably recognise yourself in most of this:

• You have owned and shipped real features across frontend and backend, and you enjoy the whole stack rather than a slice of it.
• You are strong with TypeScript and React, and/or with Python and a modern web framework, and happy to become strong in the other.
• You can make the bigger architectural calls and have them still look right in six months.
• You already build with AI tools and have a genuine view on where they help and where they get in the way.

Bonus, not essential: React Native, AWS, GraphQL, CI/CD, or having shipped LLM features to production. None of this is a checklist. If it sounds like you, even without every box ticked, get in touch.

This is a chance to build the infrastructure for the most fragmented and most painfully manual industry there is. Cortile is at the point where a small, sharp team can shape both the product and the way we build it, right as we step up to a bigger market. You would join early enough to leave real impact on both, with a genuine path into technical leadership for the right person.

1. 01Email us your CV, or a project you're proud of.
2. 02Intro call (30 mins) with one of the engineering team.
3. 03Take-home task (max 2 hours), or send us something you have built recently instead.
4. 04Technical interview (1 hour): half on your take-home or what you sent across, half on a systems design question.
5. 05A half-day working with us in the office. Real work, alongside the team. Paid, of course.
6. 06Culture fit: a final conversation with our founder.

We will always aim to get back to you quickly between stages.
