Software Engineer III

Granum builds software for landscaping and arborist businesses. The Software Engineer III will develop and operate critical services for the LMN Estimates product, collaborating with product and design partners to deliver customer-focused improvements and reliable software.

Responsibilities:

• 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
• 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

Requirements:

• 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
• Granum does not sponsor work authorization needs; candidates must have proper work authorization to work for any employer in Canada or the U.S, without sponsorship from the company
• 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
