Our Values

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

Who You Are

Are you passionate about design and development? Do you have experience building, deploying, and maintaining large-scale applications and/or consistent, user-friendly experiences? 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 in the Platform Services cluster, you will help evolve our software architecture to support more parallelized development against multiple products without compromising the quality that has defined success for Justworks so far. You will leverage your experience working within a service-oriented architecture with a strong understanding of API, library, and framework design. 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 across multiple dimensions - in code, practices, processes, people, and customers. You want to understand how systems work, and you think about how to make them work even better. You will work closely with multiple domain teams to scope, design, and build new features and common functionality. You will be working primarily in Ruby on Rails, Kotlin, and/or JavaScript/Typescript + React, but prior knowledge is not a requirement.

Your Success Profile

What You Will Work On

  • Implement product-oriented platform services that help modularize and enable our domain teams
  • Collaborate with various teams to find solutions to customer challenges, both internal and external
  • Take ownership of designing and developing functionality that is exposed via web and mobile applications
  • 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.”

Just Be You

We work hard to reflect the world we want to see by leading with diversity, equity, inclusion and belonging (DEIB) principles and want to ensure that people from all backgrounds and experiences feel welcomed, supported, and empowered to potentially join the Justworks team.

Participation in this survey is completely optional. Any responses you choose to share will not be associated with your application and will not in any way be used in any hiring decision.  We are collecting this information to establish a better understanding of our candidate pool and meet commitments related to DEIB as we seek to be representative of the wider world.

At Justworks, we are building an open, inclusive, and collaborative culture that values people and their individual potential in the collective service of our company, our community, and our customers. Our DEIB mission is to help every Justworker grow with confidence and realize their full potential.  

We are leading the industry by transparently holding ourselves accountable for our representation and culture of inclusion by sharing our progress. Starting in 2022, we are releasing DEIB statistics on an annual basis. We know we can always do more to advance DEIB, but we are also proud of the company we are building, one great Justworker at a time.
