Senior Software Engineer; Frontend

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. We've found a unique wedge into this huge market and are growing quickly.

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.

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 Type Script + 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.

• 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 Type Script + React (functional components, hooks, Material
  
  UI)
• Apply a deep understanding of React state management & lifecycle to architect predictable, maintainable UIs
• Use Graph
  
  QL (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
• 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

• 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

• 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)

• Salary range: $165,000 - $185,000 annually (final offer within this range will depend on experience and skills)
• Health & wellness benefits
