Senior Front-End Engineering

Job Description 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.

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. 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.

About 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'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.

This position is based in our San Francisco office where our engineering team collaborates in-office 4 days a week. 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

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
• Experience modeling relational data
• Proven ability to deliver projects end-to-end: from architecture to production

~ Bonus points for:

Experience in SaaS or complex web applications

Construction tech, ERP, or billing/payments domain knowledge

Building shared libraries or developer tooling

Creativity - You like to express yourself creatively through hobbies or interests outside of coding

Challenging problems - not "yet another CRUD app"

In-office with purpose - we collaborate in-person in our SF office centrally located near Union Square 4 days a week, with weekly team lunch

Builds fail when the foundation is faulty. We're stronger than reinforced concrete when we support each other.

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.

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.
