Senior Software Engineer

Why Gravitate?

Gravitate’s mission is to elevate the fuel industry through intelligent automation and connected data. We help organizations buy, price, sell, dispatch, and deliver fuel with greater accuracy, transparency, and control. Our vision is to achieve full autonomous supply and dispatch, redefine how fuel is sold over the rack, and connect the market end-to-end through Crossroads—our unified data platform that brings together refiners, wholesalers, retailers, carriers, and customers. Our goal is simple: empower the fuel market to operate smarter, faster, and more profitably with every gallon.

What will you be doing?

Gravitate provides AI-enabled collaboration, automation, and decision support software for the fuel space. As a Senior Software Engineer, you will work within our backend team to design, build, evolve, and own backend services and APIs that power Gravitate’s intelligent automation and connected data platform.

In this role, you will operate with a high degree of autonomy and influence—shaping technical direction, driving architectural decisions, and raising the engineering bar across the team. You’ll partner closely with product, data, and AI teams to translate complex business problems into scalable, maintainable systems.

We are looking for a clean programmer who gets excited about solving hard problems, thinks in systems, and wants to be part of an organization where they can strategize and execute best-of-class solutions end-to-end.

You are an ideal candidate if:

• You have deep experience developing software with modern programming languages such as Python, and can make informed trade-offs in language, framework, and tooling choices.
• You have strong experience designing and developing web application backends and APIs, particularly in distributed, service-oriented systems.
• You are comfortable owning system design—from data modeling and API contracts to performance, scalability, and resiliency.
• You feel comfortable working with data persistence technologies such as MongoDB, MSSQL, Postgres, MySQL, MariaDB, both in terms of practical application and designing, optimizing, and troubleshooting production systems.
• You are comfortable working with Agentic AI for development (Claude Code, Gemini CLI, etc.) and can thoughtfully integrate AI-assisted workflows into engineering practices.
• You are excited to work on AI / ML / mathematically-driven optimization and understand how these systems integrate into real-world, production software.
• You are passionate about the art and craft of coding, including readability, maintainability, and long-term ownership.
• You are a lifelong learner who embraces change and helps others grow through mentorship, code reviews, and technical guidance.

Minimum qualifications:

• 7+ years of professional software engineering experience with one or more general-purpose programming languages and established design patterns, preferably Python.
• Extensive experience designing, building, and maintaining JSON/REST APIs in production environments.
• Strong experience working with relational and/or NoSQL databases such as PostgreSQL, MySQL, or MongoDB.
• Proven ability to design and optimize SQL queries, stored procedures, database views, and overall data access patterns for performance and reliability.
• Solid understanding of data structures, algorithms, and system design principles, applied pragmatically to business problems.
• Experience using standard development tooling including IDEs, database administration tools, and version control systems (Git).
• Strong critical-thinking and problem-solving skills, with the ability to reason through complex business and technical scenarios.
• BS in Computer Science, Engineering, or equivalent real-world technical experience.

Preferred qualifications:

• Working knowledge of Docker, CI/CD pipelines, Git workflows, and MongoDB in production environments.
• Experience with application orchestration technologies such as Kubernetes, including deployment, observability, and operational considerations.
• Experience contributing to or leading technical architecture discussions, platform evolution, or cross-team initiatives.
