ABOUT SITELINE

Siteline is a Series A SaaS startup in the construction space. We're a team of 25 full-time employees who live and work remotely across the US, with a small in-person office in San Francisco.

What problems are we solving?

We're on a mission to modernize finance for construction, an industry that employs 1 out of every 10 workers, but lacks good software tools to get the job done. Payments in construction are fundamentally broken — the antiquated billing process hasn't evolved in decades, and construction is one of the slowest industries to get paid in. We've found a unique wedge into this huge market and are growing quickly.
 

Why are we building this?

Millions of hardworking people are affected by this broken system — in turn making construction more expensive and inefficient for society every year. When everyone up and down the chain is on the same page with payments, contractors can focus on actually building, instead of mountains of paperwork. We’re reimagining construction finance to help contractors get paid, grow their business, and build a better future for all of us.

The Role

We’re looking for a seasoned engineer and frontend technical lead — someone who can design and ship complex product features from the first line of code to production launch.

This is a frontend-heavy role that demands full-stack fluency and a product mindset. You won’t just implement designs - you’ll work directly with product and design to shape them, making smart, user-focused tradeoffs along the way. You’ll spend much of your time in TypeScript + React, but you’ll also model data in Postgres, debug backend services, and work on integrations with the systems our customers rely on.

We’re a small, senior team building Siteline - a billing platform for the construction industry. The problems here are complex and nuanced, but rewarding: modeling deeply nested financial data, orchestrating complex API syncs, and making it all feel effortless for the user.

What You’ll Do

  • Weigh in on product direction - collaborate with product and design to shape features, make tradeoffs, and ensure we’re solving the right problems for our users
  • Build high-impact product features in TypeScript + React (functional components, hooks, MaterialUI)
  • Apply a deep understanding of React state management & lifecycle to architect predictable, maintainable UIs
  • Use GraphQL (Apollo) to power type-safe data flows between frontend and backend
  • Model and manage complex nested/relational datasets for billing, compliance, and analytics
  • Contribute to backend services to support frontend features
  • Write clear design docs, QA plans, and deployment strategies for your projects

What We’re Looking For

  • 4+ years of professional software engineering experience
  • Proficiency in React - especially state management, lifecycle patterns, and Hooks
  • Strong full-stack fluency - comfortable making schema changes, debugging API calls, and tuning backend queries
  • Track record as a product engineer - you think deeply about user workflows, not just code paths
  • Experience modeling relational data
  • Proven ability to deliver projects end-to-end: from architecture to production
  • Strong collaboration skills and a desire to work in a small, senior, high-trust team

Bonus points for:

  • Experience in SaaS or complex web applications
  • Construction tech, ERP, or billing/payments domain knowledge
  • Accessibility best practices, or advanced PDF/file handling
  • Building shared libraries or developer tooling
  • Creativity - You like to express yourself creatively through hobbies or interests outside of coding

Why Siteline

  • Small but mighty - everyone here is excellent at what they do
  • Impact from day one - you’ll shape product decisions and see your work live quickly
  • Challenging problems - not “yet another CRUD app”
  • Hybrid with purpose - we collaborate in-person in our SF office with views of the Bay, Chinatown, and North Beach
  • Low-ego culture - smart, kind teammates who care about doing great work (and are really fun to be around)

What to include in your application

Please include your LinkedIn profile and/or resume. 

Optional: add a super brief note about what you’re looking for in your next role (problems you enjoy, scope you want). No cover letter required!

Company values

Move Quickly, Together
Speed is our advantage, but alignment is our path to victory. We will go farthest, fastest if we work in unison. Prioritize the mission, establish clear owners and deliverables, and execute with confidence.
 
Reach for the Sky
We are curious, open-minded, and courageous. We challenge ourselves and each other to ask more questions, push boundaries, and deliver excellence every day.
 
Run Lean
Construction is a scrappy industry where companies must do more with less. Same here. Operate efficiently, optimize strategically, and always get the most bang for our buck.
 
Be the Steel
Builds fail when the foundation is faulty. The same is true for us. Exercise good judgment, deliver on your commitments, and know your capacity—every base has its threshold, after all. Most importantly, back your teammates. We’re stronger than reinforced concrete when we support each other.
 
Build Our Fanbase
Our mission is to grow the size of the pie for everyone in construction. We only achieve that audacious goal if we keep our customers front and center. Work tenaciously to build smarter systems that solve real problems for our customers, positively impact their businesses and lives, and make them loyal fans.
 
Shoot Straight
We speak directly, candidly, and respectfully. We prioritize transparency, err on over-communicating, and understand that differing opinions and perspectives are part of a healthy company. Ultimately, it’s okay to disagree with—but still commit to—the chosen direction.
 
At Siteline, we're looking for people with passion, grit, and integrity. We encourage you to apply even if your experience doesn't precisely match the job description. Your skills and passion will stand out—and set you apart—especially if your career has taken some extraordinary twists and turns. We know that diverse perspectives foster the innovation we need to be successful, and we are committed to building a team that encompasses a variety of backgrounds, experiences, and skills. We celebrate diversity and are committed to creating an inclusive environment for all employees. We do not discriminate based on race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status. Join us!
