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.
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. 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 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.
This position is based in our San Francisco office where our engineering team collaborates in-office 4 days a week. We're big believers in trust and in a healthy work/life balance: we want you to be productive and connected with the team, but we're not here to micromanage.
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
