We're hiring a Software Engineer 3 (P3) for the LMN Estimates product pod. LMN is the platform our customers run their entire business on, with the Estimates pod focusing on how our customers create profitable and winning bids. You'll work in a pod of 2–4 engineers with a Product Manager, Designer, and Test Engineer, shipping to production continuously.

You will build and improve critical services end-to-end. You'll design, build, ship, and operate, partnering closely with the Product Manager and Designer to turn customer pain into shipped product. At Granum, we measure success by customer outcomes, not pull requests.

• Partner hand in hand with your PM and Designer to shape what gets built and how it gets built.

• Own critical services and make them noticeably more reliable, performant, and pleasant to work in.

• Build complex systems end-to-end.

• Make the engineers around you better with thoughtful reviews and clear documentation.

• Anticipate failure modes, build guardrails, and follow through on post-incident learnings.

Our 2026 Engineering operating principles:

• Customer Focus: Every decision ladders back to "did this help the landscaper?"

• Shipping: Small changes, low risk, fast feedback; velocity with robust process.

• Efficiency: Every tool at our disposal, from AI agents to scripts, to make work repeatable.

• Simplicity: Start simple, prefer boring industry-standard tech.

• Get Good at AI: Every engineer is expected to use, improve, and help shape our AI-assisted development practices.

• Performance & Reliability: Clear, measurable bars for performance, uptime, and time-to-restore; regressions are first-class work.

Engineering always aligns with Product's operating principles — Be the Partner, Raise the Bar, Big Vision Small Scope, Shipping is Discovery. All of our engineers treat product partners as teammates.

• Backend: C# / .NET, multi-tenant service architecture, Azure SQL Server, Azure Functions

• Frontend: Angular, TypeScript, Shared Component Libraries

• Agentic AI development: Internal orchestration layer that enhances Claude and Cursor across the dev lifecycle

• Cloud / Delivery: Azure, Terraform, Cloudflare, GitHub Actions, LaunchDarkly

• Observability: Datadog (APM, RUM, logs)

• AI-forward in practice - you use coding assistants and agentic workflows today, can speak credibly about where AI helps and where it hurts, and are willing to grow adoption on the team.

• Strong communication and collaboration - clear writing, useful reviews, low ego in disagreements.

• Highly curious – you want to know how things work: our code, our company, and our customers.

• Systems thinking - you reason about latency, consistency, and scale trade-offs and write the design doc that aligns your pod on a hard call.

• ~4+ years of professional software engineering experience (depth of impact matters more than the number).

• Shippable experience with C#/.NET and Angular (or a closely related modern framework). Comfortable in Azure SQL Server and a modern cloud.

• Operational ownership - you're comfortable on-call, you instrument what you ship, and reliability is part of the feature.

• Values fit - you have bias to action, you're transparent about trade-offs, and you're accountable to outcomes.

• Eligibility - legally eligible to work in the US or Canada.

• You've shipped AI-enabled features or engineering workflows and have opinions on guardrails and evaluation.

• You've worked in multi-tenant SaaS and know the operational realities.

• You love building real solutions for users collaboratively.

• A clear career track from P3 → P4 → P5 with concrete expectations for promotion to Senior and beyond.

• A small, focused engineering org where Engineers actually have leverage. Your work affects the way we build and how we ship.

• A direct line of sight from your code to the landscapers and arborists running their businesses on it.

• A team that enjoys working together, takes ownership seriously, and is transparent in retros.

• Join a team culture that’s all about collaboration, support, and having fun while making a real impact every day.
• In the U.S., we offer comprehensive medical, dental, and vision coverage with multiple plan options, plus additional add ons like HSA/FSA accounts, disability and life insurance, and more.
• In Canada, we provide an employer-funded HSA-based benefits plan with drug, dental, and mental health coverage - giving you a flexible way to manage your healthcare needs.
• We're committed to your financial future, with 401(k) matching for U.S. employees and RRSP matching for those in Canada.
• We invest in your growth through tailored career development conversations and support for tools, courses, and resources to help you thrive.
• And when it comes to work-life balance? We offer unlimited Paid Time Off, paid company holidays, and a company-wide winter break from December 24 to January 1 - so you can truly recharge.
