Role

Who you are

  • 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
  • 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.”
  • Minimum of 5 years of professional hands-on experience
  • Strong object-oriented design and coding skills
  • Solid understanding of data structures and algorithms
  • Prior experience in fraud detection and prevention strongly preferred
  • Experience building new feature from scratch, using clean, organized, and scalable code
  • Experience supporting other engineers and acting as a “tech lead”
  • Experience working with complicated systems at scale
  • Experience working using Agile/Scrum methodology in a fast-paced environment
  • Experience in a high-growth environment working with deadlines and milestones

What the job involves

  • As part of the larger Employer Risk vertical, Fraud Prevention is a new team built from the ground up
  • The team will focus on building the backend services and frontend experiences and toolings to automate and scale the detection and prevention of fraudulent entities and activities in the Justworks platform
  • We work closely with cross functional partners across multiple business domains
  • As a Senior Software Engineer in the team, you will be one of the founding engineers to build 0 to 1 software services and tools
  • 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, UX designers, and other engineers to scope, design, and build new features and functionality
  • You will be working primarily in Ruby on Rails and/or JavaScript/React, but prior knowledge is not a requirement
  • Collaborate with a cross functional team to build solutions to detect and prevent fraud
  • Take ownership of designing and implementing APIs, systems integrations, data models and backend services
  • Promote engineering excellence through technical leadership, knowledge-sharing and mentorship
  • Instate best-practices observability and monitoring as “first principles” of all our services
  • Keep extremely sensitive data compartmentalized and secure
  • Perform other related duties as assigned

Our take

Justworks operates in an increasingly crowded space of all-in-one business operation suites, that include tools like human resources, payroll, employee management, benefits, and others that businesses critically need to operate as they scale.

Globally, human resource management has become an extremely fertile field, worth over $20 billion annually and predicted to grow to over $50 billion annually by 2030 - creating great opportunity for Justworks to continue to grow. The company is regarded as a market leader, but does see competition in the shape of Paychex Flex, Rippling, Paylocity, and TriNet, among others.

Solutions delivered by Justworks have proven to be extremely popular with SMEs, and this has not gone unnoticed by investors, with the company picking up exceptional amounts of funding. Justworks is known to have sights on going public, though action towards this end has been delayed until global mass-market conditions have settled from a period of volatility. However, the company's acquisition of
