Machine Learning Software Engineer - Agentic AI

TL;DR:

Hiring skilled Senior/Staff ML Software Engineers for a Venture-backed Agentic AI Startup. Ideal candidates are polyglots who love solving tough problems. You’ll build a system that can autonomously modernize legacy codebases at scale using AI and LLMs. This is NOT vibe-coding, this is no-code rearchitecture and code modernization for enterprise-scale code bases with millions of lines of code.

• $200K - $300K+ (or competitive) base, benefits, and potential equity
• Fully Remote in US (open to other countries, United States preferred)

POSITION DETAILS:

This isn’t your average engineering role. We're building what no one else has: fully autonomous systems that can modernize legacy software codebases at scale. Imagine an AI that doesn’t just autocomplete lines of code—but can understand, refactor, migrate, and test entire systems. That’s the mission.

We’re looking for engineers who aren’t afraid of the unknown. Who get excited about building things that have never been built. Who want to be part of a close-knit, ambitious team led by repeat founders and backed by tier-one investors. This is your chance to build foundational infrastructure for the future of software development with top engineers around the world!

What You’ll Do:

• Architect the Future: Build AI-first systems that understand and rewrite legacy code across languages, frameworks, and platforms.
• Solve the Impossible: Tackle ambiguous, moonshot problems with no playbook—and invent the tools to solve them.
• Work Across the Stack: Touch everything from low-level system design to distributed infrastructure to model orchestration.
• Build AI-Native Systems: Integrate machine learning and LLMs into robust, production-grade pipelines.
• Lead and Influence: Drive strategy, mentor peers, and shape a high-performance engineering culture from day one.

What You Bring:

• Deep Technical Fluency: You’ve built real systems at scale. You’re a polyglot - fluent in at least a few languages (Python, C++, JavaScript, etc.) and aren’t scared of learning more.
• ML/AI Experience: Solid grounding in ML, statistics, or LLM applications—ideally with experience training or deploying models.
• Startup Energy + Big Thinker: You thrive in ambiguous environments and love taking big bets on the future.
• Full-Stack Versatility: You’re equally comfortable designing system architecture, shipping backend code, and iterating on ML models.
• Collaborative Mindset: You enjoy working with other sharp thinkers to push each other and the product further.

Why Join:

• Moonshot Mission: Build a system that fundamentally changes how code is written, maintained, and modernized.
• Proven Leadership: Join a team led by second-time founders and technical experts with a track record of success.
• Tier-One Backing: Work with the support and resources of top investors who believe in this vision.
• Remote First: Globally distributed by design but tightly connected in ambition and execution. HQ in the SF Bay Area. Preference for US based.

Comp Package: $180,000 - $320,000 base (depending on experience) + benefits and Pre-IPO equity
