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.\nWhat problems are we solving?\nWe'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.\nWhy are we building this?\nMillions 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.\nAbout the Role\nWe’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.\nThis 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.\nWe’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.\nThis 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.\nWhat You’ll Do\nWeigh 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\nBuild high-impact product features in TypeScript + React (functional components, hooks, MaterialUI)\nApply a deep understanding of React state management & lifecycle to architect predictable, maintainable UIs\nUse GraphQL (Apollo) to power type-safe data flows between frontend and backend\nModel and manage complex nested/relational datasets for billing, compliance, and analytics\nContribute to backend services to support frontend features\nWrite clear design docs, QA plans, and deployment strategies for your projects\nWhat We’re Looking For\n4+ years of professional software engineering experience\nProficiency in React - especially state management, lifecycle patterns, and Hooks\nStrong full-stack fluency - comfortable making schema changes, debugging API calls, and tuning backend queries\nTrack record as a product engineer - you think deeply about user workflows, not just code paths\nExperience modeling relational data\nProven ability to deliver projects end-to-end: from architecture to production\nStrong collaboration skills and a desire to work in a small, senior, high-trust team\nBonus points for:\nExperience in SaaS or complex web applications\nConstruction tech, ERP, or billing/payments domain knowledge\nAccessibility best practices, or advanced PDF/file handling\nBuilding shared libraries or developer tooling\nCreativity - You like to express yourself creatively through hobbies or interests outside of coding\nWhy Siteline\nSmall but mighty - everyone here is excellent at what they do\nImpact from day one - you’ll shape product decisions and see your work live quickly\nChallenging problems - not “yet another CRUD app”\nIn-office with purpose - we collaborate in-person in our SF office centrally located near Union Square 4 days a week, with weekly team lunch\n Low-ego culture - smart, kind teammates who care about doing great work (and are really fun to be around)\nSF Pay Range\n$183,000—$220,000 USD\nCompany values\nMove Quickly, Together\nSpeed 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.\nReach for the Sky\nWe are curious, open-minded, and courageous. We challenge ourselves and each other to ask more questions, push boundaries, and deliver excellence every day.\nRun Lean\nConstruction 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.\nBe the Steel\nBuilds 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.\nBuild Our Fanbase\nOur 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.\nShoot Straight\nWe 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.\nAt 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.
