Member of Technical Staff Location: San Francisco, CA, New York City, NY, or Birmingham, AL (remote available) Type: Full-time Reports to: CTO The role As a Member of Technical Staff, you'll work on whatever the most important technical problem is — backend, frontend, infrastructure, APIs, data, or something we haven't thought of yet. The title is intentionally broad because the work is too. You'll take real ownership of our core product, help scale the APIs developers use to integrate with Linq, and work across teams wherever your skills are needed most. This role is for someone who is curious about everything, moves fast, and doesn't need to be pointed at the problem. Apply if you: - Are a strong generalist who's gone deep on at least a couple of things - Have shipped production code at a company where speed and quality both mattered - Can pick up a new codebase and start contributing without a lot of hand-holding - Default to action over process - Have experience with our stack: React/Next.js, TypeScript, Go, Python - Have a background building or working with APIs at scale - Are familiar with cloud infrastructure (AWS, Azure, Heroku, Docker) - Have startup experience — you've operated where priorities shift weekly and nobody tells you what to do twice Why Linq? - Health/Dental/Vision insurance - Flexible PTO - 401(k) - Wellness stipend, book stipend, professional development opportunities - Direct access to engineering leadership - we're a small team solving real problems with no layers of bureaucracy between you and the work - Experience Birmingham, AL — affordable living, incredible food, and a rising tech scene (remote welcome too)
