Summary
👤
Senior🎓
Top SchoolWiktor Macura is a software engineer and seasoned engineering leader with 14–15 years of experience building and scaling backend systems and teams across startups and high-growth companies. He joined early-stage ventures and scaled engineering organizations through Series A to IPO-ready maturity, growing teams from single digits to 50+ across mobile, backend, data, and ML. His hands-on roots—ranging from low-level scalable infrastructure at Tumblr and Wolfram Alpha to product-driven platform work at Square and Citizen—give him fluency across systems, data, and user-facing products. He has a track record of turning intuition-driven development into data-informed product practices, having built a data science function from scratch. Now based in New York and currently contributing to Jane Street’s electronic trading platforms, he combines deep technical craftsmanship with pragmatic team-building and a persistent appetite for creation. An early coder who has repeatedly bridged technical depth and organizational growth, he thrives on delivering measurable utility for end users.

My family emigrated from Poland to the USA a year after I was born. Both my parents came for post-doc fellowships after completing their PhDs, and were largely dissatisfied with public schooling. They encouraged me to pursue academics early, and as a result, I received a scholarship to the University of Maryland when I was 12, studying Math and Computer Science. I initially found academic work stimulating, but as I became exposed to applied work through internships at NASA, Wolfram Research, and a company using ML to provide network security for the DIA, I became increasingly bored with academics. This led me to eagerly accept the opportunity to join Wolfram Research when I was 16., My family emigrated from Poland to the USA a year after I was born.
