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.

🕺 The Role

Siteline is hiring a Senior Backend Engineer to lead the next evolution of our integrations platform.

We power billing and compliance workflows for construction subcontractors, with integrations sitting at the core of our product. We’re looking for a senior engineer to architect, build, and own the mission-critical integrations with external ERPs and construction industry platforms.

You will design resilient, real-time data pipelines, navigate the complexities of imperfect third-party systems, manage sync state at scale, and build extensible systems that enable the rest of the engineering team to move faster.

This role is based in our San Francisco office (3-4 days/week). We are not considering fully remote candidates at this time.

🧰 Our Stack

Backend

Node.js, TypeScript, GraphQL, PostgreSQL, Redis

Integrations

A mix of direct API calls, database connections, and third-party vendor integrations — each with its own quirks and challenges

Durable Functions

We use Inngest for reliable, resumable workflows: retries, fan-out, and long-running processes without the infrastructure headache

Observability

Monitoring is a first-class concern. We rely on searchable dashboards, structured logging, and OpenTelemetry Dash0 to debug issues fast and keep integrations running reliably

What You’ll Do

🔌 Own our integrations platform

Architect and build direct integrations with ERPs and construction platforms
Design bi-directional data sync systems with clear ownership, observability, and retry logic
Handle edge cases like rate limits, partial failures, inconsistent schemas, and long-running jobs
Build internal tooling that makes integrations easier to develop and support

🧠 Think in systems

Design durable data models that map external systems to Siteline’s domain
Establish patterns for idempotency, backfills, migrations, and versioning
Improve reliability, monitoring, and performance of integration workflows

🤝 Partner cross-functionally

Work closely with product and customer teams to understand real-world ERP workflows
Translate messy external APIs into clean internal abstractions
Support customers through tricky integration edge cases when needed

📈 Raise the technical bar

Make pragmatic architectural decisions
Write high-quality, well-tested backend code
Mentor more junior engineers working on integration-adjacent projects

👀 What We’re Looking For

Senior-level backend experience

5+ years building production backend systems
Strong experience in API design, async processing, job queues, and distributed systems

Integration experience (required)

Experience building and maintaining integrations with third-party systems
Familiarity with REST APIs, GraphQL, webhooks, OAuth, data mapping, and sync architectures
Experience handling unreliable or legacy external systems

Systems thinking

You’ve designed systems that need to be resilient, observable, and maintainable
You understand tradeoffs around data integrity, retries, and eventual consistency

Clear communicator

You proactively surface risks and unknowns
You can explain complex systems to both engineers and non-technical teammates

Startup-ready

Comfortable operating with ambiguity
Able to make progress without perfectly defined requirements

🍪 Brownie Points

Experience integrating with:
- ERP systems
- Accounting software
- Construction tech platforms
- Financial or payment systems
Experience with:
- Event-driven systems
- GCP / Cloud Run

Company values

Move Quickly, Together

Speed 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.

Reach for the Sky

We are curious, open-minded, and courageous. We challenge ourselves and each other to ask more questions, push boundaries, and deliver excellence every day.

Run Lean

Construction 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.

Be the Steel

Builds 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.

Build Our Fanbase

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.

Shoot Straight

We 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.

At 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. Join us!
