Role Summary
An exciting opportunity to kick-start your career as a junior software engineer in a fast-growing, office-based, hands-on team. This role is ideal if you enjoy being a broad generalist - someone who likes connecting systems, figuring out how different technologies work together, and building practical solutions that make things happen.
You’ll be working across a range of projects and products, helping to integrate services, move data between systems, and turn complex processes into reliable, working software. We don’t expect you to know everything upfront - what matters most is your curiosity, your willingness to learn by doing, and your interest in understanding how real-world systems fit together.
