Senior Software Engineer - Backend​/Infrastructure

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.

As a senior member of our small but mighty engineering team, you'll work closely with our cross-functional product team to conceptualize, implement, and ship features from start to finish, as well as own the maintenance and evolution of our backend tech stack and infrastructure. Whether iterating on core workflows, driving product initiatives, or building critical infrastructure, you'll be thinking nonstop about how to improve our customers' experience and scale the product.

And, you'll be an early member of the Siteline team and lend your unique voice and perspective to the shaping of not just the product, but the company itself.

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.

• Technical leadership: Employ software engineering best practices to ensure our codebase remains well-tested and bug-free. As an early engineer, you’ll have a prominent voice in engineering decisions and technical direction across the stack.
• Infrastructure: Guide the future of our tech stack. To support greater usage and a larger customer base, our infrastructure needs to evolve, as does the way we store, query, and process data. You’ll not only be a key decision-maker, but will anticipate technical constraints and proactively find and engineer solutions.
• Systems design: Independently drive decisions on software architecture, data modeling, and infrastructure that scale with our customer base and perform reliably for our users.
• Product development: Work closely with the engineering and product team to plan, architect, and implement features. Your work will lean heavily toward the backend and API, but you’ll collaborate closely with frontend engineers and always think holistically about the product.
• Integrations: Build and maintain robust integrations with third‑party platforms—some modern and well‑documented, others more outdated and opaque. You’ll grow to be a leader on the team’s integrations ecosystem and an expert on our external‑facing systems and solutions.
• Team building: Be an active part of shaping Siteline's culture, helping to recruit and mentor new team members and cultivating a positive, inclusive, and collaborative work environment.

• Experience: Minimum of 4-6 years of professional software experience, including meaningful backend experience and exposure to full-stack work. You've designed and scaled complex backend systems, worked with internal and external APIs, and shipped to real customers on a regular basis.
• Modern tech: Familiarity working with Node.js, Type Script, GraphQL, React, and Postgres.
• Problem solver: You're good at understanding and breaking down complex problems. You are resourceful and comfortable with ambiguity, and can make good decisions and forward progress even when requirements are unclear.
• Product focused: You take pride in building scalable,…
