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

You are self-driven and like to work with others to remove roadblocks. You are curious, and love to explore and learn new technologies. You have demonstrated the ability to build, deploy and maintain large-scale, complex applications. You care more about solutions and impacting the customer experience than using a particular tool or framework.

What You Will Work On

As a Senior Software Engineer for Workforce Payments, you will work with the team that builds the core computation layer powering Justworks’ payroll, money movement, and tax calculation products, ensuring our customers can confidently and accurately pay their workforce.

This team is mission-critical, operating at the heart of our platform's financial accuracy and compliance. You will lead technical decision-making and be expected to take initiative in identifying projects that will enable us to meet key business goals, such as scaling our tax and money movement capabilities, improving the integrity of our financial ledger, and developing robust platform interfaces for payroll data. We’re looking for people who have a passion for solving real-world, complex financial problems and will thrive building a growing team focused on reliability and precision.

• Independently own large‑scoped projects from initial discovery through launch with a focus on outcomes and customer impact
• Collaborate with a cross functional team to find solutions to customer challenges
• Improve the performance, reliability, and scalability of our existing systems
• Promote engineering excellence through technical leadership, knowledge‑sharing and mentorship
• Add capabilities to our high‑volume, fault‑tolerant processing infrastructure
• Enhance our testing, monitoring and continuous deployment infrastructure
• Keep extremely sensitive data compartmentalized and secure

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:

Good judgment - the exercise of critical thinking, analyzing and assessing problems and implications, identifying patterns, making connections of underlying issues, understanding risks and developing mitigation strategies, and taking ownership of the outcome.

Resourcefulness - taking a can‑do approach, even in the face of obstacles and constraints by assessing what’s in front of you and effectively and efficiently optimizing what you have, whether it’s working on something new or thinking about how to do something better.

Teamwork and communication - putting our collective best together through documentation, collaboration, relationship‑building, listening, empathy, recruiting, and evangelism. Influence and leadership - fostering a community of knowledge‑sharing, collaboration, mentorship, and forward‑thinking.

Skills and knowledge - the capacity to actively learn and apply specific domain knowledge, know‑how, and best practices to continually enhance and improve.

In addition, all Justworkers focus on aligning their behaviors to our core values known as COGIS. It stands for:

• Camaraderie - Day to day you can be seen working together toward a higher purpose. You like to have fun. You’re an active listener, treat people respectfully, and have a strong desire to know and help others.
• Openness - Your default is to be open. You’re willing to share information, understand other perspectives, and consider new possibilities. You’re curious, ask open questions, and are receptive to thoughts and feedback from others.
• Grit - You demonstrate grit by having the courage to commit and persevere. You’re committed, earnest, and dive in to get the job done well with a positive attitude.
• Integrity - Simply put, do what you say and say what you’ll do. You’re honest and forthright, have a strong moral compass, and strive to match your words with your actions while leading by example.
• Simplicity - Be like Einstein: “Everything should be made as simple as possible, but no simpler.”

Qualifications

• Minimum of 5 years of professional hands‑on experience
• Mastery of modern server side languages, Golang is a plus but not required

• Proficiency with cloud infrastructure management, preferably AWS
