About the role
As a full-stack engineer, you’ll feel at home if you are hands-on, grounded, opinionated and passionate about building things using technology. Our tech stack ranges widely with language ecosystems like Typescript, Java, Scala, Golang, Kotlin, Elixir, Python, .Net, Nodejs and even Rust.
This role is ideal for those looking to have a large impact and a huge scope for growth while still being hands-on with technology. We aim to allow growth without becoming “post-technical”. We are extremely selective with our consultants and are able to run our teams with fewer levels of management. You won’t find a BA or iteration manager here! We work in small pizza teams of 2-5 people where a well-founded argument holds more weight than the years of experience.

- Build frameworks and supporting tooling for data ingestion from a complex variety of sources. Work in short sprints to deliver working software with clear deliverables and client-led deadlines.
- Willingness to be a polyglot developer and learn multiple technologies.
Skills you’ll need
- A maker’s mindset. To be resourceful and have the ability to do things that have no instructions.
- Extensive experience (at least 10 years) as a Software Engineer.
- Deep understanding of programming fundamentals and expertise with at least one programming language (functional or object-oriented).
- A nuanced and rich understanding of code quality, maintainability and practices like Test Driven Development.
- Experience with one or more source control and build toolchains.
- Working knowledge of CI/CD will be an added advantage.
- Understanding of web APIs, contracts and communication protocols.
