Senior Frontend Engineer

Location:
Seattle, WA (On-site / Hybrid)

We’re looking for an experienced Senior Frontend Engineer to own and lead
the entire user experience layer of a mission-critical enterprise platform used
daily by cities, utilities, and infrastructure teams across North America. This
is a high-impact, high-autonomy role where you’ll define the future of our web
(and eventually mobile) frontend architecture from the ground up.

What You’ll Own

• 
  Selecting and establishing the
  modern frontend stack and long-term roadmap
• 
  Designing and driving a scalable,
  shared component library that works across web and mobile
• 
  Modernizing our frontend codebase
  while dramatically improving performance, reliability, and developer
  velocity
• 
  Setting the quality bar:
  architecture, testing strategy, performance budgeting, accessibility, and
  engineering hygiene
• 
  Mentoring and leveling up a
  growing team of frontend engineers
• 
  Partnering closely with Product
  and executive leadership to translate customer needs into delightful,
  high-performance experiences
• 
  Measuring and continuously
  improving real-world client-side performance (load times, memory, offline
  behavior, etc.)

Requirements

What You Bring

• 
  8+ years of professional
  experience building complex web applications
• 
  Mastery of JavaScript/TypeScript
  and deep expertise in at least one modern framework (React, Vue, Angular,
  or similar)
• 
  Proven track record of owning
  frontend architecture decisions at scale
• 
  Hands-on experience with advanced
  browser APIs, especially IndexedDB, caching strategies, and offline-first
  patterns
• 
  Strong focus on measurable
  client-side performance and data-driven optimization
• 
  Obsession with code quality: high
  test coverage, design systems, linting, CI/CD, and tooling that makes
  teams move faster
• 
  Experience working directly with
  end users or customers to shape product direction
• 
  Exceptional communication skills
  — you can explain technical trade-offs to both engineers and non-technical
  executives
• 
  Demonstrated ability to thrive in
  fast-paced, ambiguous environments and drive consensus across teams
• 
  Customer-obsessed mindset with a
  history of championing “delighter” features that users love

Nice-to-Haves

• 
  Experience shipping desktop apps
  (e.g., Electron or similar)
• 
  Background in API design or
  full-stack development
• 
  Familiarity with relational or
  NoSQL databases
• 
  Proficiency in a compiled
  language (Java, C#, Go, Python, etc.)
• 
  Hands-on experience with major
  cloud platforms (AWS, Azure, GCP)

Who Thrives Here

You’re someone who gets excited about building foundational systems that
will be used for the next decade. You care deeply about both pixel-perfect
experiences and rock-solid engineering. You’re comfortable being the most
senior frontend voice in the room while remaining humble, collaborative, and
eager to mentor others.

If you’re ready to own the entire UX platform of a growing, product-led
company and set a new standard for what great frontend engineering looks like
in enterprise software, we’d love to hear from you.

Apply with your resume and a brief note about a frontend modernization
project you’re particularly proud of.
