Summary
Steve Marshall is a seasoned engineering leader with 17 years of experience, currently directing Firefox Desktop engineering at Mozilla after transforming UK government digital services. He built and scaled platform engineering at the UK Ministry of Justice from scratch—growing teams to ~70 engineers, migrating ~500 services to cloud-native hosting, and delivering over £15M in annual savings while forecasting far greater future efficiencies. Comfortable both as a hands-on engineer and strategic leader, he blends a dot-com product mindset with reliability-focused practices for 24×7 critical services. Known for fostering open, autonomous engineering cultures, he empowers six teams (~65 people) to experiment and ship user-centred solutions. Steve’s background spans full-stack development, platform and SRE practice, API design, and developer experience across companies like Expedia and Yahoo. Outside work he’s unusually disciplined about bonsai care and brings the same patient experimentation to architecture and team development.
