Rockstar🎓
Top SchoolMarcin Wyszynski is a seasoned software leader and co-founder with 14 years of experience building cloud-native infrastructure and developer-facing products. As Spacelift’s Chief R&D Officer (and formerly Chief Product Officer and CEO), he blends hands-on engineering with product and security leadership, having written much of early product v1. He is a proactive open-source contributor—co-founding OpenTofu and contributing backend fixes and Terraform-related refactors to notable projects like OpenTofu and go-gitlab—helping keep FOSS cloud tooling interoperable and vendor-neutral. His background includes SRE and production engineering roles at Google and Facebook, giving him deep operational expertise in large-scale systems. Based in Warsaw, he pairs formal training in software engineering with a social-science perspective from MA studies in sociology, an uncommon mix that informs pragmatic product decisions. Colleagues describe him as pragmatic and efficient—“smart but lazy” in the best sense: optimizing for simplicity and automation.
