Staff Software Engineer, Agentic Platform

About the role

Founded in 2021, Axion is at the forefront of transforming product quality and customer satisfaction in manufacturing. Our cutting-edge AI-powered platform empowers manufacturers to swiftly identify, thoroughly investigate, and effectively resolve quality issues while simultaneously elevating customer experiences and outcomes. As trailblazers in end-to-end quality intelligence, we're setting new industry standards. Our innovative approach enables industrial, aerospace, consumer, and medtech manufacturers to harness the power of quality and post-market data, driving down costs and boosting business performance. Our vision extends beyond mere problem-solving; we're committed to reshaping the future of manufacturing. By seamlessly integrating advanced AI technology with deep industry expertise, Axion is paving the way for smarter, safer, and more efficient production processes across diverse sectors. Backed by leading investors, including Bessemer Venture Partners, Amplo, Boeing, and RTX Ventures, Axion is poised to lead the quality revolution in manufacturing. We're looking for an experienced Staff Software Engineer to help architect and scale the agentic systems at the core of the Axion platform. This is a senior individual contributor role: you'll own design decisions that determine how our agents reason, act, and integrate with enterprise data, working in close partnership with Engineering and Product leadership. The hard problem is the data-customer, service, field, telematics, warranty, and aftermarket signals that are disconnected and mostly unstructured-and the bar is high, because an agent's conclusion can drive a recall or a redesign. The ideal candidate thrives in early stage companies, has deep experience building complex, data-intensive systems, and knows what it takes to make non-deterministic, LLM-driven systems reliable in production.

Responsibilities

• Own technical architecture for our agentic systems-orchestration, tool use, memory, retrieval, evaluation, observability, and the guardrails that keep agents reliable when the input data is noisy and incomplete.
• Build and harden the reasoning layer and infrastructure that take customer data from ingestion through agent-driven reasoning to root-cause insight, at the scale and reliability manufacturers require.
• Establish rigorous evaluation and testing for non-deterministic systems-measuring agent accuracy against expert-validated ground truth and the outcomes customers track: detection rates, investigation speed, and warranty cost.
• Partner across Engineering and Product to shape the technical vision and roadmap for the agent platform.
• Raise engineering standards through code review, design docs, and the technical direction others build on.
• Mentor engineers on agentic patterns and system design, unblocking hard problems and sharing context generously.

Requirements

• Minimum 7+ years of software engineering experience, with recent, hands-on focus on building agentic systems (LLM orchestration, tool/function calling, multi-step and multi-agent reasoning, retrieval and context engineering, and interoperability protocols such as MCP, or comparable work).
• Demonstrated ability to design and own complex distributed systems, ideally in data-intensive B2B SaaS environments.
• Hands-on fluency with the modern agentic stack and a strong intuition for the failure modes of non-deterministic, LLM-driven systems-plus the evaluation and observability practices needed to tame them.
• Experience turning messy, heterogeneous real-world data into something a model can reason over reliably.
• A track record of technical mentorship; you make the engineers around you better without needing formal authority.
• A firm believer in a "Data First" philosophy who can make sound decisions in ambiguous, fast-moving situations.
• A strong executor in fast-paced environments who can balance shipping MVPs with a commitment to production-grade systems.
• You're a builder and operator who thrives in fast-moving, high-accountability environments. You take pride in getting things done - thoughtfully, efficiently, and without drama. You're energized by ambiguity, skilled at bringing clarity, and comfortable flexing between strategy and execution.
• You don't need constant direction - you create momentum. You take ownership for outcomes, and you expect the same from those around you.
• How We Operate:
• We move fast, work smart, and hold ourselves to a high bar. Axion is a place for people who take pride in their craft and are motivated by meaningful work. We respect time off and boundaries, but we're also realistic: hard problems some
