Engineering Manager at Marshmallow
Attica, Greece
Summary
👤
Senior🎓
Top SchoolNikolas Kaloumenos is an engineering manager with 8 years of experience scaling startups from single squads to 20+ engineers and shipping high-impact platform and product work. He excels at removing organisational friction—ownership gaps, dependencies, and technical debt—while staying close to the system so plans change only when necessary. At Marshmallow he led migrations and platform initiatives that improved performance, cut costs, and unlocked new revenue and operational controls (e.g., a DynamoDB migration, real-time sales ledger, and self-serve collections recovering substantial funds). Currently leading Context & Data at Panther, he combines product thinking with engineering craft to deliver what the business truly needs, not just what was asked for. Based in Attica, Greece, he pairs hands-on technical chops from early founding-engineer roles to SLT-level roadmap ownership, and he’s particularly excited about the pragmatic opportunities AI brings to software development.
