4 weeks ago
Are you passionate about 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 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
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.
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:
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
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
