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.
