[Hiring] Senior Backend Engineer @Gravitate Energy LLC

Role Description

If you are considering this role, you are someone who has stopped waiting to be handed well-defined work. You take a large, ambiguous problem, break it into a plan, and drive it to production — unblocking yourself and the people around you along the way.

You’ll own a significant area of Gravitate’s fuel logistics platform — or a full service — and be accountable for its reliability, performance, and evolution over time. That means leading design for complex features, evaluating real trade-offs between performance, maintainability, and cost, and documenting the decisions so the next engineer understands them.

You’ll go deep on the backend:

• Python services and APIs
• Data modeling in MongoDB
• Async and event-driven processing
• Running on Kubernetes in GCP and Azure

You’ll also be one of the people we count on when something breaks in production — finding root cause quickly, driving recovery, and then driving the monitoring, observability, and performance improvements that keep it from happening again.

Seniority here isn’t just scope of code — it’s scope of influence. You’ll mentor our mid-level engineers, raise the bar in code and design review, and lead technical initiatives without needing formal authority to do it.

We’re strongly against artificial separations of responsibility and throwing work “over the wall.” As a senior engineer here, you’re part of the product team — in the room for the product conversation, not downstream of it.

Qualifications

• You deliver large things, accurately.
• You take a big feature with real unknowns, break it into a plan, estimate it honestly, and land it. When it slips, you raise the risk early instead of hoping.
• You design before you build.
• You can hold performance, maintainability, and cost in your head at the same time, pick a direction, and explain why.
• You own your work in production.
• You make the engineers around you better.
• You have strong opinions and hold them honestly.
• You know the business, not just the codebase.
• You want to work in an AI-enabled workflow.

Requirements

• 5+ years of professional software engineering experience building and operating production backend systems
• Deep expertise in multiple areas of a backend stack: a primary server-side language (Python preferred), API design, data modeling, and automated testing
• Demonstrated track record of delivering large features end-to-end, on plans you built yourself, with moderate unknowns
• Experience owning a service or major product area in production — including its reliability and performance, not just its features
• Strong debugging and troubleshooting skills on medium-to-large issues; comfortable participating in on-call for what you own
• Working knowledge of infrastructure, security, and observability, plus CI/CD and deployment practices
• Experience mentoring junior and mid-level engineers and giving high-quality code review feedback
• Strong written and verbal communication — able to produce clear medium-to-large technical documents and explain trade-offs to non-technical stakeholders
• Openness to utilizing and becoming an expert in AI-assisted development to supercharge your ability to get stuff done.

Benefits

• Hands-on experience with our stack: Python, MongoDB, Kubernetes, GCP or Azure
• Comfort reaching into React/TypeScript when a feature needs it end-to-end
• Backend engineering experience in a B2B SaaS or enterprise software environment
• Background in a logistics, supply chain, or energy/fuel domain
• Performance and scale work against large data volumes — query optimization, caching, and profiling
• AI engineering experience – working with production agentic systems and ML / operations models.
