Engineering: the heart of Fluency
An award-winning culture you can’t find anywhere else
Focus on what matters most,
not the red tape
We know that coders want to code. Our engineers have time to actively focus on what they love: coding innovative solutions to meaningful problems.
Whether it’s building APIs or integrating new technologies into our system, you’ll spend more time coding than you will in meetings.
Own your builds and
make your mark
At Fluency, you’ll own your projects from conception to deployment. (Of course, you’ll have a stellar team to support you along the way.)
We believe in giving our engineers the autonomy and trust they deserve to create their best work. Our goal is to empower you to make impactful decisions and contribute across systems—without micromanagement.
Join a supportive, people-first organization
We value our people above all else. Everyone at Fluency is dedicated to cultivating a positive and supportive work environment that encourages learning, growth, and individuality.
The way you feel outside of work is just as important as how you feel at work. That’s why we offer top-notch healthcare (for families, too), competitive salaries, and true downtime when you’re off the clock.
Future-proofing,
not firefighting
Well-tested, high-quality releases are the bedrock of our products. You can focus on doing your best work instead of rushing to ship subpar solutions.
We’re also committed to maintaining clean, efficient systems. Spend your time designing new solutions instead of constantly patching or fixing outdated code.
See and feel the difference you
make for our clients
The problems we’re solving are intricate: scale, distributed systems, and real-time data processing. That’s why we’re looking for collaborative, ambitious, and curious engineers who want to test their skills.
Best of all, our solutions deliver direct and tangible benefits to our customers. See how your hard work makes a difference, every day.
