Role
Who you are
- Expertise with a variety of back end technologies. We primarily work with Python, SQL, Bash, and Rust, but we value your breadth of problem-solving abilities with various languages such as Go (Golang), Elixir, C++, Java, or similar
- Experience designing, building, and managing data systems, preferably with Kubernetes, Postgres, Kafka, and Snowflake
- A track record of leading large-scale technical transformation projects, such as migrating from monolith to microservices (or vice versa) or modernising system architecture
Desirable
- A strong numerical or technical background, ideally with a degree in maths, physics, computer science, engineering, or a related field
- Active participation in tech or open-source communities, with a passion for sharing knowledge and inspiring others
- An open mind and the flexibility to approach challenges from different perspectives
- Strong communication skills, with the ability to translate complex business needs into effective technical solutions
What the job involves
- As the Principal Back-End Engineer, you'll shape our tech strategy, inspire the adoption of new technologies, and ensure technical initiatives align with company goals
- This role combines vision and leadership with hands-on coding to push the organisation towards smarter and more efficient ways of working
- You’ll identify and lead a range of strategic technology projects, driving improvements across our systems, platforms, and infrastructure to support innovation, efficiency, and growth, such as:
- Modelling Platform Enhancements: Lead the evolution of our platform to make it simpler for teams to define, discover, and manage model features. You will improve data transformation and visualisation capabilities, enabling more intuitive use of data
- Data Warehouse Optimisation: Drive enhancements to our data warehouse, making it a more effective resource for the business, ensuring teams can access and leverage data more easily
- Python Codebase Improvements: Spearhead initiatives such as adding static typing to our Python codebase, increasing its reliability, security, and maintainability
- Accelerating Deployment Speed: Work with the back-end team to increase the deployment speed of our Django monolith. This may involve breaking the monolith into microservices or implementing other innovative approaches to improve efficiency
- Systematic Upgrades: Proactively identify weaknesses in our infrastructure and systems. You will lead efforts to strengthen and optimise our technology stack, ensuring it is scalable, secure, and future-proof
- Emerging Technology Research: Stay ahead of the curve by researching emerging trends and tools. You will recommend and lead the adoption of new technologies that provide a competitive edge and improve operations across the business
- You’ll join the Core Systems team, responsible for driving innovation across the business by optimising development, building data systems, and continuously improving iwoca products
- We follow Agile-inspired processes, using continuous integration and delivery, so features go live in days or weeks, not months or years

Company values
- Motivated: Going to work shouldn't feel like a slog, so we want everyone in the team to personally care about what they're working on. We stay motivated by celebrating our wins, learning from our mistakes, and always looking for new gaps to step into.
- Smart: At iwoca being smart isn't about what you know, it's about how you think. Smart thinking means looking at each problem by asking ‘why’ first, then figuring out ‘how’.
- Humble: We know all ideas are flawed, all code has bugs, and everyone makes mistakes - it’s how we learn. For us, being humble means you question yourself first, rather than your team.
- Growth Mindset: We think there's always a better way to solve a problem. So we never let ourselves get comfortable with being good enough.
