Senior Front-End Engineer

About the role

We’re looking for a Senior Front-End Engineer to take ownership of our front-end platform and multiply the team’s output by being thoughtful, opinionated, and AI-fluent in how that work gets done. This isn’t an execution-only role. You’ll spend roughly 70% of your time in the codebase, make architecture and tooling decisions that the rest of the team builds on, and teach the team what you learn along the way.

Responsibilities

• Own the front-end stack end-to-end — architecture, component patterns, build tooling, and CI/CD for the front-end codebase. Set the direction, then ship against it.
• Build and maintain scalable web experiences using React, TypeScript, Node.js, Tailwind, and modern deployment platforms like AWS Amplify and Vercel.
• Drive the front-end refactoring roadmap — identify systemic risks, propose pragmatic refactors, and sequence them against feature delivery without stalling either.
• Collaborate with design, product, marketing, and engineering to ensure alignment across initiatives, and translate design intent into resilient, performant interfaces.
• Contribute to A/B tests, feature flags, and analytics implementations to support data-driven decision making.
• Work with APIs and microservice-driven architecture to integrate features and improve performance.
• Mentor the team on platform discoveries — through code review, pairing, internal docs, and short tech talks. You’ll surface patterns and pitfalls; teach those, so the whole team levels up.
• Deliver well-documented, high-quality code that improves site speed, accessibility, SEO, and overall customer experience.

Requirements

• Deep proficiency with React, TypeScript, Node.js, and Tailwind, with the ability to design component architecture for non-trivial applications and defend your tradeoffs.
• Production Next.js experience — you can pick a rendering strategy (SSR/SSG/ISR/CSR) based on business and infrastructure constraints, and explain why.
• Experience deploying and maintaining apps in Vercel, AWS, and Amplify.
• Hands-on experience with A/B testing frameworks (Amplitude, Segment, GA4, or equivalent), feature flags, and CMS integrations/migrations (especially headless).
• Solid understanding of API integrations and working in microservice-driven environments, including holding your own in API design conversations.
• Performance instincts — you profile before you optimize, and you know what Core Web Vitals are measuring and how to move them.
• Build tooling and CI/CD ownership — you’ve configured, debugged, and improved real pipelines, not just consumed them.
• Demonstrated experience with GitHub for version control and working within CI/CD pipelines to ensure efficient, reliable, and automated delivery of front-end applications.

AI-Forward Expectations

• You actively use AI coding tools (Claude Code, Copilot, Cursor, or equivalent) and have opinions about when they help and when they don’t.
• You can show concrete examples of AI-assisted work that shipped — production code, refactors, or tests, not toy demos.
• You’re comfortable establishing team patterns for AI use: prompt conventions, review practices, where to trust output, where to verify.
• You see AI fluency as a leverage activity. One AI-fluent senior should compound the team’s velocity, and you understand why.

Business & People Expectations

• Communicate progress and results effectively through release notes, video walkthroughs, and demos.
• Partner cross-functionally with product, design, and marketing teams to deliver high-impact initiatives.
• Coordinate with engineering peers on QA automation and backend support.
• Mentor more junior teammates — through code review, pairing, and sharing what you learn during the replatform. This is leverage, not overhead.
• Influence the front-end roadmap — bring technical insight that helps product partners make better tradeoff decisions.

Preferred Qualifications

• 5–8 years of professional front-end engineering experience, with at least 3 in a senior or ownership-level capacity.
• Previous work in e-commerce environments strongly preferred.
• Background in SaaS or digital product development a plus.
• Experience with performance optimization, accessibility, SEO, and analytics best practices.
• Experience with headless CMS and design system / component library ownership.
• GraphQL experience (schema design, federation, or client-side patterns) a plus.

Our Ideal Candidate

• A strong problem solver who can work independently and deliver reliable solutions while still bringing the team along.
• Naturally collaborative, able to work smoothly with multiple stakeholders across product, design, and engineering.
• Embraces a team-first mindset and contributes to a positive engineering culture — including mentoring teammates as a default behavior, not a chore.
• Curious and adaptable, with a willingness to learn and improve continuously, especially as tooling and AI workflows evolve.
• Has opinions, lightly held — comfortable advocating for an approach and equally comfortable changing course when the evidence shifts.

Schedule

• Full-time position, hybrid — must reside within approximately 90 miles of Longmont, CO.
• One day per week onsite in the Longmont office.
• Standard schedule: Monday – Friday, 40 hours/week.
• Rare after-hours work (1–2 times per year).
• Potential for ~1 week of travel per year for team gatherings or key meetings.

Pay

Pay Range: $145,000 – $165,000. Final offer depends on demonstrated scope, depth of front-end ownership, and counteroffer environment.

Must be authorized to work in the United States. We are not sponsoring visas for this role.

Benefits

• Excellent health, dental, and vision coverage (PPO and high-deductible options).
• Annual company contribution toward HSA for high-deductible plan enrollees.
• Life insurance and short-term disability insurance covered at 100%.
• Voluntary benefits: accident & critical illness, long-term disability, identity theft insurance.
• Flexible PTO and paid holidays.
• Paid maternity leave (FMLA qualified) and parental leave.
• 401(k) with company contributions.
