Senior Software Engineer in Denver

Gravitee is a 2025 Gartner Magic Quadrant Leader, on a mission to govern the world’s intelligence.

We deliver the industry’s most advanced platform for Any API, Any Event, and Any AI Agent, trusted by global leaders like Michelin, Roche, and Blue Yonder.

Why join us?

• The Mission : We are the first to bridge traditional API Management with the new frontier of AI Agent Security
• The Momentum : A high‑growth Leader - combining market credibility with startup speed
• The DNA : We hire people who Hold Nothing Back - passionate builders who want to redefine digital infrastructure

Don’t just watch the AI revolution. Build the infrastructure that controls and secures it.

The Role:

AI is reshaping how organizations build, ship, and scale digital products and APIs are the connective tissue that makes it possible.

As a Senior Software Engineer, you’ll play a critical role in shaping impactful product areas by collaborating within high‑velocity engineering pods and partnering with product managers, all while leveraging AI to automate the routine and focus your energy on high‑value building.

You will take ownership of a vertical slice of the product, balancing the quality of the code with the quality of the outcome.

What You’ll Be Doing

At Gravitee, impact isn’t abstract, it’s visible. In this role, you will:

70% Engineering: Technical Excellence & Speed

• AI-Accelerated Prototyping : You use tools like Cursor and Antigravity to skip the boilerplate and ship working MVPs in hours. You focus on validating ideas quickly, then use your engineering rigor to turn those prototypes into robust, production- ready systems.
• Full-Stack Delivery : You build end‑to‑end features, moving seamlessly between backend and frontend code.
• Debugging & Code Comprehension : You can read, trace, and reason about code. When something breaks, you dig in, follow the stack, and find the root cause. The codebase is not a black box. You understand what was built and why, and you can intervene when things go wrong.
• Software Architecture & Best Practices : You bring a strong foundation in software design patterns, security principles, and performance optimisation.
• Quality as a Feature : You write automated tests and manage technical debt, taking pride in shipping "magic" that just works.
• Developer Experience : You obsess over the DX, treating API contracts and error messages as part of the user interface.

30% Product Strategy: Discovery & Synthesis

• AI‑Assisted Synthesis : You use LLMs to process raw feedback, summarising transcripts from customer calls, support tickets, and community forum threads into concise, actionable problem statements.
• Data‑Driven Decisions : You analyse feature adoption and usage patterns to identify friction points.
• Challenge the Roadmap : You collaborate with PMs to trade off technical complexity against user value, proposing simpler solutions that capture 80% of the value.
• Direct Customer Discovery : You join customer calls to hear about their needs first‑hand, and to help understand complex issues. You use these sessions to research how users think and what their problems are.

Your impact will be visible, measurable, and global.

Essential Skills

• 5+ Years of Experience: Strong background in software engineering, with experience building complex, scalable software systems in a product or platform environment.
• Proven ability to work across backend and frontend systems. Strong experience with object‑oriented backend development, such as Java or similar, and familiarity with modern frontend frameworks such as Angular, React, or Vue.
• AI Fluency: Demonstrated ability or strong curiosity to use AI tools for code (accelerating dev cycles) and text summarisation (synthesising user feedback).
• Product Sense: Demonstrated ability to articulate why you built past features and how they impacted the business.
• Communication: Excellent written and verbal English. You can explain complex technical trade‑offs to non‑technical stakeholders.
