Senior Software Engineer

We build ShowUp, the software that runs live events end to end: check-in, badging, session scanning, lead capture, exhibitor portals. It runs in real time, on-site, where there's no second chance to get it right. We work with teams of every size, including three of the Fortune 5, across hundreds of events a year worldwide. We're hiring one senior engineer to own core platform development - improvements, integrations, reliability — and ship it end to end. You'll work with our eng lead, who sets architecture and reviews the work, while you run with a lot of autonomy. We want someone who can take an ambiguous problem, scope it, and ship it without needing it broken down first. Builder role: no reports, real ownership. We're an AI-forward team and lean on AI tooling heavily to punch above our size; we expect you to use it to amplify your judgment, not replace it. Stack: Python, Django, React, on AWS and GCP.

Looking for: 8+ years, senior experience owning complex domains, fast ramp in unfamiliar codebases, strong judgment on ambiguous work, fluent everyday use of AI tools, clear communication. Event-tech or integration-heavy background is a plus. Rate: 60-100/hr USD DoE. Individuals only — no agencies, staffing firms, or third-party recruiters.
