Senior Full-Stack & DevOps Engineer

About Truss

We started by building a B2B payment platform in Canada called MazumaGo — and discovered that most of our customers were construction companies. Contractors, subcontractors, custom home builders, flooring installers — businesses that still get paid by check because the existing digital tools ( Bill.com , Stripe, Square) weren't built for how construction actually works.

We took everything we learned and pivoted to the U.S. to build a banking and payments engine purpose-built for SMB construction, with a built-in network effect. Truss lets construction businesses send and collect payments digitally in a way that's actually easier than depositing a check — no fees, no complexity, no friction.

We soft-launched a beta in 2023, fully launched in 2024, and have been growing rapidly ever since. We're a small team (under 5 engineers), backed by Y Combinator, and scaling fast.

About the Role

We need a Senior Full-Stack & DevOps Engineer who ships fast, thinks in systems, and treats infrastructure as one part of their toolkit — not their whole identity.

At our scale, DevOps and security don't fill a full-time calendar. We need someone who can own that surface area efficiently and then spend the rest of their time building product, automating the dev cycle with AI, and helping a tiny engineering team move like a much bigger one.

You'll be working across a rapidly growing payments platform serving thousands of construction firms. The stakes are real — when something breaks, contractors don't get paid.

Our Stack

API: Python / Django

Web Client: React (TypeScript)

Back-Office: Next.js (full-stack)

Mobile: React Native

Infrastructure: GCP, Terraform, GitHub Actions

AI Agent: In-house, built with Agno (Python)

Tooling: Sentry, Incident.io , Linear, Graphite

What You'll Do

• Ship features end-to-end. Build across the Django API, React TS web client, Next.js back-office, and React Native mobile app. You're an engineer first — product work is the majority of your time.

• Automate the dev cycle with AI. Build AI-powered PR reviews, automated code comments, Sentry-to-patch pipelines that turn incidents into fixes, and automated QA funnels. Contribute to our in-house Agno-based AI agent.

• Own infrastructure and CI/CD. Manage our GCP infrastructure with Terraform, maintain GitHub Actions workflows, and keep builds, deploys, and uptime monitoring running smoothly.

• Own security and compliance. Lead security audits, manage IAM and access controls, maintain information security policies (Separation of Duties, Data Management, BC/DR), and support SOC 2 compliance.

• Manage incident response. Configure Incident.io , build automated incident-to-resolution workflows, and participate in on-call rotations.

• Your First 90 Days

• Days 1–30: Learn the codebase by shipping small issues across the stack. Get feedback from the team. Start evaluating our infrastructure and security posture.

• Days 31–60: Own a full-stack feature end-to-end — scope it, build it, ship it, working alongside the team. Begin drafting action plans for any infrastructure or security gaps you've identified.

• Days 61–90: Measure the impact of what you shipped and proactively iterate based on feedback and data. Start rapidly implementing your infrastructure and security action plans.

What We're Looking For

• 6+ years of software engineering experience with strong full-stack skills — Python/Django, React/TypeScript, and ideally Next.js or React Native

• Solid DevOps and infrastructure experience — GCP (or equivalent), Terraform, GitHub Actions/workflows, CI/CD pipelines

• Genuine enthusiasm for using AI tools (LLMs, code assistants, custom agents) to automate development workflows and eliminate toil

• Experience with or strong interest in building automated PR review, code quality, and incident response pipelines

• Understanding of information security, IAM, and compliance in a fintech or regulated environment

• A bias toward action and urgency — you ship fast, communicate proactively, and don't wait to be told what to do

• Comfort switching contexts between infrastructure, product features, and automation projects in the same week

• Builders, not maintainers — we want someone who's thrived in early-stage environments, not just operated within established corporate systems

• Nice to Have

• Experience building AI/LLM-powered developer tools or agents (bonus if you've worked with Agno or similar Python agent frameworks)

• React Native experience and comfort shipping across web and mobile

• Familiarity with Sentry, Incident.io , Linear, or similar modern DevOps/project tooling

• Experience in payments or banking infrastructure

• Experience owning compliance programs (SOC 2, PCI-DSS) in a startup environment

• Why Truss

• Real scale, tiny team. Rapidly growing payment volume, under 5 engineers. Your work has outsized impact.

• Construction is wide open. Most construction firms still run on checks. We're digitizing an industry that's barely been touched.

• AI-first engineering culture. We're serious about using AI to multiply what a small team can do — you'll have room to experiment and build.

• Fully remote with biannual company-funded team meetups.

• Competitive salary and equity.
