La Fosse has partnered with a customer engagement partner to recruit a Principal Engineer to join their growing team. This role is focused on shaping scalable, integration-led platforms, playing a key part in defining technical strategy and driving architectural decisions across a complex digital ecosystem. This is a great opportunity for someone who enjoys balancing architectural ownership with technical leadership, in a role that is predominantly strategic (circa 80%) with some hands‑on involvement.
You’ll operate at a senior level, working closely with engineering and business stakeholders to design robust, cloud‑native solutions, while remaining close enough to delivery to guide implementation and ensure best practice.
