Who We Are

At Justworks, you’ll enjoy a welcoming and casual environment, great benefits, wellness program offerings, company retreats, and the ability to interact with and learn from leaders in the startup community. We work hard and care about our most prized asset - our people.

We’re helping businesses get off the ground by enabling them to focus on running their business. We solve HR issues. We’re data-driven and never stop iterating. If you’d like to work in a supportive, entrepreneurial environment, are interested in building something meaningful and having fun while doing it, we’d love to hear from you.

We're united by shared goals and shared motivations at Justworks. These are best summed up in our company values, which are reflected in our product and in our team.

Our Values

If this sounds like you, you’ll fit right in.

Who You Are

Are you passionate about system design and development? Do you have experience building, deploying, and maintaining large-scale, distributed applications? Are you ready to take your skills to the next level and join a team of innovative self-starters in a supportive, entrepreneurial environment?

As a Senior Software Engineer, you will be leveraging your experience working within a service-oriented architecture. You will be responsible for separating data and functionality as necessary, and will demonstrate an understanding and use of automated testing as a productivity multiplier. You are eager to learn and passionate about improvement. You want to understand how systems work, and you think about how to make them work even better. You will work closely with product managers, designers and other engineers to scope, design, and build new features and functionality. You will be working primarily on backend systems. We’re currently using Ruby on Rails as our main language, but prior experience in RoR is not a requirement.

Your Success Profile

What You Will Work On

The Onboarding teams transform a weeks-long, support-heavy onboarding process into a fully self-serve experience, leveraging AI-powered data ingestion and real-time validation to take companies from signed contract to running payroll in a matter of days. A core part of this work is unifying how people join Justworks — today, full-time, contractor, and international hires across PEO, ASO, and EOR each follow entirely different flows, and this role brings them all into one. Ultimately, this is about building the first product experience every new customer has. If onboarding feels hard, nothing else matters — making this role a direct driver of activation rate, time-to-first-payroll, and onboarding completion.

How You Will Do Your Work

As a Senior Software Engineer, how results are achieved is paramount for your success and ultimately result in our success as an organization. In this role, your foundational knowledge, skills, abilities and personal attributes are anchored in the following competencies:
