Full Job Description
Role Overview

We're looking for a senior full stack software engineer who loves to build and ship. You'll design, build, and own features end to end across our HR, payroll, and benefits platform - from technical design through deployment and support - writing clean, well-tested code that holds up in production.

You'll work closely with product, design, and other engineers to turn complex requirements into simple, reliable software. We use AI tools heavily to move faster, and we expect you to as well - but we hire for engineering judgment first.

Key Responsibilities

Build & Ship
  • Design, build, test, and maintain features across the stack, owning them from technical design through production
  • Write clean, maintainable, well-tested code and contribute to a healthy, scalable codebase
  • Break large problems into shippable increments and deliver them on a predictable cadence

Quality & Reliability
  • Own the reliability of the systems you build - monitoring, debugging, and resolving production issues
  • Care about security, performance, and data integrity in a domain where accuracy is non-negotiable
  • Help improve engineering practices: testing, code review, CI/CD, and tooling

Collaboration
  • Partner with product and design to scope work, clarify requirements, and propose practical solutions
  • Give and receive thoughtful code reviews and technical feedback
  • Communicate clearly about trade-offs, progress, and risks with both technical and non-technical partners

How We Build
  • Use AI tools as part of how you build - to accelerate design, coding, testing, and debugging
  • Mentor engineers and help raise the bar for the team

Qualifications
  • 5+ years of professional software engineering experience building and shipping production software, preferably in B2B/SaaS
  • High agency. You don't wait to be told. You see a gap and fill it.
  • Strong fluency in at least one modern programming language and the ability to work effectively across the stack
  • Experience designing, building, and operating web applications and APIs in production
  • Expert in C# with an understanding of OOP and application architecture.
  • Proficient in SQL, Transact-SQL (T-SQL), with an understanding of relational database design.
  • Experience creating and consuming services and data.
  • Disciplined coding, with a commitment to maintain a team-defined framework/architecture.
  • Expert at researching bugs and providing effective solutions.
  • Solid grasp of fundamentals: data modeling, testing, version control, and CI/CD
  • You use AI tools (Claude Code, Cursor, Codex, etc.) as part of how you build - and you have the judgment to know when to trust them and when not to

Nice to have
  • Experience in HR tech, payroll, benefits, fintech, or other complex, data-heavy domains
  • Front-End Web Development skills: HTML, CSS, JavaScript ("raw" + common libraries), Responsive Web Design (RWD).
  • Experience with Vue.js, or other common JS libraries and frameworks (Angular, React, etc.).
  • Experience with Agile methodologies and tools.

Compensation & Benefits
  • Competitive Salary
  • Health insurance 100% paid by employer (for both employee and family!)
  • Additional voluntary supplemental benefits including dental, vision, life insurance, disability, accident, critical illness, etc.
  • 401(k) with company match
  • Paid holidays and paid time off

Job Type: Full-Time. Job Location: Lindon, Utah (In-Person/Hybrid)
