Applied AI Engineer

At Squint, we're building technology that matters. While many tech companies focus on digital-first industries, we've set our sights on empowering the 80% of the global workforce that keeps our world running: frontline manufacturing operators. From soda cans to tires, toothpaste to chocolate bars, chips to napkin holders, these are the people who build the things you touch and see every single day. Our platform transforms manufacturing operations by putting AI and AR capabilities directly at workers' fingertips, creating what we call "agentic manufacturing" – where every team member has the power to make informed decisions in real-time using practical, applied artificial intelligence tools.

Our technology serves Fortune 500 leaders across Automotive, Consumer Packaged Goods, and Life Sciences industries. These companies trust Squint to capture and activate their essential operational know-how, resulting in measurable improvements: reduced downtime, minimized waste, and optimized productivity at scale.

We raised a $40m Series B at a $265m valuation and are backed by elite investors including Sequoia Capital, Menlo Ventures, TCV and The Westly Group. Our co-founders have been recognized on Forbes' 30 Under 30 for Manufacturing and Industry, and Fast Company named us one of the most innovative augmented and virtual reality companies of 2025.

Squint is looking for AI Engineers to turn the messy, fractured world of manufacturing knowledge into real intelligence that changes the industry. You’ll build the capabilities that transform real-world inputs—tribal knowledge, video, images, documents, and more—into differentiated insights and structured workflows for frontline manufacturing teams. If you love shipping fast, owning problems end-to-end, and iterating with real users, you’ll fit right in.

Ship AI-powered features rapidly—from prototype to production to customer reality. This includes work such as:

• Transform unstructured manufacturing inputs into structured knowledge.
  Build and iterate on systems capable of semantically understanding a wide variety of manufacturing material (documents, media, and more) and representing them with high fidelity on the Squint platform.

• Develop best-in-class reasoning experiences.
  Build systems that leverage this structured knowledge serve fast, accurate answers directly to the shop floor–where there is no margin for error.

• Leverage differentiated data to produce novel, domain-specific insights for manufacturers.
  Create methods that synthesize information and surface meaningful signals for customers.

• Build advanced photo- and video-based visual understanding.
  Iterate on AI systems that interpret manufacturing environments and actions, improving accuracy, speed, and robustness across varied conditions.

• Creating evaluation and feedback loops.
  Build generic, reusable tooling for evaluating AI systems over time. Instrument product flows to gather automatic feedback and continually improve correctness, prevent regressions, and accelerate iteration.

• 8+ years shipping production software, with significant experience deploying AI/ML systems. Staff-level capability in applied AI/ML is expected.

• Deep understanding of the transformer architecture and modern LLM techniques. You can explain how attention mechanisms work and stay current with the latest research and techniques.

• Production experience with ML frameworks (PyTorch preferred). You're comfortable with loss functions, training loops, optimization, and the practical details of getting models into production.

• Experience fine-tuning and deploying LLMs in production environments. You've shipped LLM-powered features and understand the tradeoffs between prompt engineering, fine-tuning, and RAG approaches.

• A builder’s mindset. You move fast, pick up new skills, and take ownership from “why” to “shipped”.

• Strong product intuition and customer empathy. You care about trust, failure modes, and real-world workflows.

• Comfort with ambiguity and a bias toward action, iteration, and measurable results.

• You are the limit of your impact. You’ll own problems end-to-end, drive outcomes for the business, and change an industry.

• Real-world results. You’ll build AI systems that are used in production every day at the world’s largest manufacturers.

• High product ownership. You’ll work closely with customers and GTM, iterating fast based on what matters most.

• Unparalleled learning curve. You’ll work across AI, product, and systems with huge ownership.

Based out of our office in San Francisco, we love the energy of in-person collaboration.
