Job Description

Jawnt partners with organizations to provide their members access to
transportation. We’re on a mission to make transportation more accessible for
everyone while encouraging public transit and active transportation whenever
possible. Based in Philadelphia but remote-friendly, Jawnt is a seed-stage
start-up at the intersection of fintech, HR tech, and mobility.

**About The Role:**
We are seeking a Senior Full-Stack Software Engineer to join our high
performing engineering team as we continue to grow the business and execute
across multiple challenging domains.

Jawnt is a fast-paced, early-stage startup tackling complex challenges across
multiple business domains for enterprise and government clients. Working here
is like playing a video game on “Hard Mode”—it’s dynamic, demanding, and
incredibly rewarding. To thrive at Jawnt, you’ll need exceptional
prioritization skills, a proactive sense of urgency, and the ability to stay
focused under pressure while delivering high-quality results.

**What You’ll Do:**

* Design, develop, and implement end-to-end web functionality using Next.js and FastAPI using existing components and patterns
* Develop and optimize high-volume message queues for efficient and reliable processing of business-critical workflows
* Ship code that improves our infrastructure, continuous delivery, observability, and internal tooling across the entire stack
* Improve others through code reviews, thorough documentation, and mentorship.
* Participate in the architectural review board, providing valuable technical advice and contributing to strategic technical discussions

**Who You Are:**

* 5+ years of experience in software development with strong computer science fundamentals
* Experience in our technology stack- Next.js, Python, Flask, FastAPI, Celery, PostgreSQL, Redis, RabbitMQ, Terraform, Kubernetes, Datadog
* Experience with unit testing, functional testing, and acceptance testing in a continuous integration / continuous delivery (CI/CD) environment
* Deep understanding of relational databases, normalization, and SQL
* Deep understanding of modern cloud architecture (containerization, k8s, monitoring)
* Language agnostic

**Benefits and Compensation:**

* Salary: $140-155,000
* Equity: 0.05-0.2%
* Comprehensive benefits package: unlimited PTO, health and dental coverage, life insurance, 401k
* $100/month transit credit on your Jawnt Pass

At Jawnt, our company value “All aboard!” isn’t just about transportation—it’s
about inclusion. We’re building a team that reflects diverse perspectives and
experiences, and we encourage you to apply even if you don’t check every box.
If your career has taken you on a jaunt through unexpected paths, we’d love to
hear your story.

Jawnt is proud to be an equal opportunity employer.
