Diffco is looking for a Full Stack AI Engineer to join a fast-scaling SaaS team building AI-native software. You’ll speed up the delivery of AI features, help shape the architecture behind agentic workflows, and support the rollout of a company-wide rebrand.
What you’ll do- Own AI-powered features from concept to production, with a center of gravity in the backend and LLM integration layer
- Build and maintain the plumbing behind AI agents, RAG workflows and API integrations with LLM providers such as OpenAI and Anthropic
- Refactor and modernize legacy services, designing them to be AI-ready
- Partner with product, design and research colleagues across a distributed team
- Ship design changes tied to the rebrand — typography, assets and UI components
- 8+ years of engineering experience, including proven work on SaaS/B2B products
- Deep proficiency in Type Script, Node.js, React and PostgreSQL
- Production experience putting LLMs into real systems: prompt engineering, tool use, context management
- Working knowledge of agentic frameworks (Lang Chain, Llama Index or comparable) or experience building custom agent pipelines
- Solid grounding in system design and enterprise-scale performance
- A bias toward shipping quality work quickly
- Hands-on time with vector databases — pgvector, Pinecone, Weaviate
- Legacy system migrations or multi-region infrastructure experience
- An agentic mindset: you build autonomous, outcome-driven systems rather than isolated features
- You track the AI tooling landscape closely and hold informed opinions about what’s worth adopting
- You communicate clearly across teams and time zones
- Competitive base salary plus performance bonuses
- 100% remote position
- Funded professional development
Meaningful, forward-looking work. You’ll build Silicon Valley products on current-generation technology stacks, frameworks and methods — with genuine time set aside to learn and level up.
A team that feels like one. Our people are a second family: thoughtful, curious colleagues who make the working day something to look forward to.
Room to grow. Keep expanding your skill set, prove what you can do, and take on greater responsibility as you go.
Culture that puts you first. We take an active interest in your goals and motivations, and we protect a work/life balance that actually holds.
