Senior Engineering Lead
Build Circle is a progressive technology consultancy partnering with scale-ups, SMEs and enterprise organisations to enhance business value, speed and quality.
As product-led consultants, we draw on real-world experience in scaling hypergrowth companies such as Just Eat and Moonpig. We provide support by integrating principal-level staff to improve capability and culture, or by standing up whole teams to tackle complex challenges swiftly. We also offer strategic guidance on architectural roadmaps, talent, hiring and scaling.
Our ethos rests on two core beliefs:
- Engineering should focus primarily on delivering value.
- We believe great people create great culture and great products.
Engineering excellence extends well beyond technical mastery—it is problem-focused, pragmatic, accountable, and humble here at Build Circle. Striking a balance between enhancements and swift delivery, we prioritise "getting things done" above all else. We take responsibility for owning delivery improvements as we go.
Flexibility is key to creating successful partnerships. We advocate a problem-first approach, working with organisations to tailor a strategy and partnership that delivers the best outcome for their goals.
You should apply if ✅
You meet the following criteria:
- You have experience leading technical teams, ideally cross-functional teams in more than one organisation.
- You are confident in developing, releasing, and maintaining web applications in a fast-paced, iterative environment.
- You're comfortable working full-stack, even if you have a stronger preference for backend or frontend.
- You have experience writing microservices on container-based architectures (e.g., Kubernetes, Docker).
- You have native experience with AWS, Azure, or Google Cloud.
- You are well-versed in Agile/Lean principles.
- You can seed new projects and repositories.
- You understand what good CI/CD looks like and how to automate quality.
