Senior Engineering Manager

Engineering Manager | Fintech · Risk & Payments · High-Load Distributed Systems
 
I build engineering organizations that ship reliable, high-load distributed systems in fintech — and grow the people who own them. 10+ years in engineering, 5+ leading teams.
 
What I do
 
Scale orgs. Grew a department from 4 to 25 engineers: team structures, hiring pipeline, agile rituals from scratch. Full people cycle — hiring, onboarding, performance reviews and calibration, growth plans, PIPs, offboarding.
Own delivery end-to-end. Cross-functional programs from system design to production rollout and post-launch reliability — across 15+ teams and 40+ services.
Run risk-critical domains. Risk scoring, real-time fraud prevention, and compliance-driven programs (PII protection, geosharding) shipped against hard regulatory deadlines.
 
Problems I get called in for
 
Delivery stalls between teams → I make dependencies explicit, sequence them, and drive to production.
Systems buckling under load → architecture reviews, SLOs, incident and postmortem discipline.
Teams outgrowing their engineering practices → levels, review process, mentoring on architecture and DDD.
 
Tech: C# / .NET, Go, distributed systems, DDD, CQRS, SOLID, TDD — enough depth to challenge architecture decisions and unblock delivery, not just track it.
 
Open to Head of Engineering / Engineering Manager roles with broad ownership and organizational scale.
