Engineering

Who You Are

You’ve been building web applications for a while now and are comfortable ramping up on an existing product quickly. You’ve mastered at least one frontend framework, and know how to build highly reliable, modular systems that many people can collaborate on at the same time without stepping on each other’s toes. You have a strong sense for good design, and won’t stop until the user experience is just right.

As a Software Engineer, you will be a part of our Frontend Engineering team, focusing on delivering products and capabilities that power Justworks products. You will leverage your experience working with customer-facing applications and design with performance and security in mind. You will be working primarily in JavaScript/TypeScript and prior experience is preferred.

  • Gather requirements
  • Partner with your team lead to produce clean, effective, on-brand user experiences
  • Implement designs with a high level of fidelity
  • Research design patterns and propose technical solutions to common web UI/UX problems
  • Coding, testing, and deploying modern web apps
  • Help hire and develop our growing team

How You Will Do Your Work

As a Frontend 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:

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.

  • 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.”
