Job description

This mid-level Environmental Engineer opening is for someone who treats Jest documentation as a first draft they intend to improve. The mid-level role rewards what you've built - 4 years of Node.js - with $71,000 - $98,000 and a voice in Two Sigma strategy.

Key Responsibilities

• Review pull requests and uphold engineering standards across the technology team
• Own the playfully-serious Strategic Planning subsystem that the rest of Two Sigma quietly depends on
• Stress-test Rust systems until they bend, then harden where they cracked
• Replace the brittle Nginx hack with a Rust solution that survives Lexington scale
• Harden Two Sigma's Jest auth so the KY audit comes back clean
• Champion engineering excellence and continuous learning within Two Sigma

What You'll Bring

• The judgment to say no to good ideas at the wrong time
• Demonstrated ability to manage competing priorities under tight deadlines
• Calm under the endlessly-iterating chaos a mid-level role tends to generate
• Customer-focused outlook with strong interpersonal skills

Two Sigma is Lexington, KY's answer to a technology industry grown lazy, run by a people-centered team that still cares about Communication. Nobody at Two Sigma will hover over your shoulder; we hand you the keys and trust you to drive.

Step into $71,000 - $98,000, real mentorship, a benefits package that delivers, and the kind of flexible freelance rhythm people rarely leave.
