AI Software Engineer

As a Senior AI Software Engineer, you’ll play a key role in launching and scaling a new AI-native product area. You’ll work in a cross-functional squad to:

• Turn ambiguous problems into well-designed, scalable AI-powered systems
• Build high-quality, LLM-driven features end-to-end - from prototype to production
• Design and integrate agentic workflows, retrieval systems, and model-orchestration pipelines
• Deliver AI solutions that make a measurable difference for customers

You’ll contribute across the stack, with a strong focus on backend APIs and services that power AI/LLM-driven functionality in expenses and procurement.

Our Current Stack

• React Node.js
• JavaScript & TypeScript
• LLM APIs (OpenAI/Anthropic/similar)
• Vector databases & retrieval pipelines

That said, our interview process is technology-agnostic. We care more about strong engineering fundamentals, applied AI/ML judgment, and a learning mindset than specific framework experience.

What You’ll Be Doing

• Design, build, and ship end-to-end AI-powered features for a new product
• Collaborate closely with Product Managers and Designers to shape technical and AI strategy
• Develop and evolve scalable backend APIs, microservices, and LLM-orchestration layers
• Build robust evaluation frameworks to test and improve model performance and reliability
• Write clean, well-tested, maintainable code - including around probabilistic/AI components
• Participate in code reviews, architecture discussions, and pair programming
• Mentor junior engineers and help raise engineering and AI-quality standards
• Contribute to a team culture of continuous learning and shared success

If you’re motivated by ownership, real customer impact, and the chance to build with AI at the core of a product from day one, this is the role for you., You might be a great fit if:

• You take pride in building reliable, high-quality AI-powered software
• You think in systems and care about long-term maintainability - including of AI/LLM pipelines
• You’ve built or shipped features using LLMs, agents, embeddings, or similar AI tooling
• You enjoy collaborating and shaping ideas early, especially where the “right approach” isn’t obvious yet
• You’re comfortable mentoring others and sharing knowledge
• You thrive in environments where you have ownership and influence
• You’re adaptable and excited to learn new AI techniques, models, and domains
