**The Opportunity**

We're looking for a Senior/Staff Design Engineer to design and build the front end of our products. You'll work in our codebase every day, in Rails views with Hotwire, Stimulus, and Tailwind, taking work from first sketch to production and owning the code you ship. What's designed is what ships, because you built it.

This is a senior individual-contributor role. Beyond your own features, you'll own our design system in code, set the patterns other engineers build on, review front-end work, and set design direction for our products alongside product. Our users are the auditors and operators on our internal team who serve procurement and finance teams at major global companies, and the software they rely on lives for a long time. Depth in our domain is part of the job here. The best design decisions come from understanding how their work actually gets done.

At Fine Tune, our core values of honesty, dedication, and vigilance foster an environment of trust, open communication, and inclusivity where everyone can do their best work. If you care about your craft, want to keep getting better, and thrive in a team that's building something meaningful — let's talk.

Our interview process includes a hands-on technical pairing session, where we'll work in code together and talk through product decisions as we go.

This is a full-time, salaried, remote position. Candidates must be US citizens and located in the United States.

**What you'll do**

**Design & Build**

• Design and build features end to end in Rails with Hotwire, Stimulus, Tailwind, and DaisyUI, from first sketch to production
• Own your code through release, including tests, accessibility, performance, and the bugs that come back
• Build and maintain the design system as code: tokens, theming, reusable components, and the guidance engineers follow without a designer in the room
• Prototype in code when it answers the question faster than a mockup
• Reach for JavaScript only where it earns its keep
• Build interfaces that hold up at real data volume: large tables, dense forms, long-running jobs
• Establish patterns for AI-powered features, such as confidence, human review, and correction

**Raise the Bar**

• Review front-end pull requests for correctness, accessibility, and fit, and explain precisely what's wrong when it is
• Raise engineers' design judgment through pairing, review, and example
• Lead design critique, audit products for accessibility and usability debt, and prioritize the fixes
• Lead tool evaluation and adoption for how the team designs and builds

**Set Direction & Shape the Work**

• Own the design direction and interaction patterns for our products
• Resolve the tension between purpose-built workflows and general-purpose surfaces across products
• Lead discovery alongside product management, and frame ambiguous problems as answerable questions
• Shape new work before it's committed to, naming design risks and what's explicitly out of scope
• Weigh approaches against the time available, and know when to cut scope and when to escalate
• Use research and prototypes to de-risk new work, and know when there's enough evidence to move on
• Coach business stakeholders to build and vet their own prototypes, including with AI-assisted tools

**Collaborate & Influence**

• Partner with product and leadership to align design direction with product and business goals
• Translate design tradeoffs into terms non-designers can act on
• Improve design workflows and handoff across concurrent product teams
• Influence priorities and the roadmap with credible, trusted design judgment grounded in evidence

**What We're Looking For**

• 5+ years designing and building product software, with substantial time shipping production front-end code
• Strong HTML, CSS, and JavaScript; comfortable debugging in the browser and reading unfamiliar code
• Comfortable in a server-rendered web app: writing view code, and working with controllers and models enough to wire up a feature (Ruby is a plus)
• Day-to-day fluency with Git, pull requests, code review, and writing tests for your UI
• A portfolio that shows both design and code: shipped work, repos, or a walkthrough of something you built
• Experience building or owning a design system in code
• A track record of setting design direction for co
