If you’re a strong C# engineer stuck in large, slow-moving environments or London burnout you’ll likely find this a very different proposition.

- Working on distributed systems, low-latency services, and data-heavy workflows

- Collaborating closely with a tight engineering team

- Interested in joining an early-stage scaling team and shaping the product.
They offer:
