Machine Learning Engineer

11 Days Old

Who we are
Percepta's mission is to transform critical institutions with applied AI. We care that industries that power the world (e.g. healthcare, manufacturing, energy) benefit from frontier technology.
To make that happen, we embed with industry-leading customers to drive AI transformation. We bring together: Forward-deployed expertise in engineering, product, and research Mosaic, our in-house toolkit for rapidly deploying agentic workflows Strategic partnerships with Anthropic, McKinsey, AWS, companies within the General Catalyst portfolio, and more Our team is a quickly growing group of Applied AI Engineers, Embedded Product Managers and Researchers motivated by diffusing the promise of AI into improvements we can feel in our day to day lives.
Percepta is a direct partnership with General Catalyst, a global transformation and investment company.
About the role
We're hiring Machine Learning Engineers who will work directly within customer teams to define and deliver high-impact AI systems. We don't build prototypes or laboratory projects - you'll design, build, and ship production-grade AI agents and workflows that drive millions in business value for customers.
Our Machine Learning Engineers: Engineer and optimize AI/ML systems : Build end-to-end ML pipelines for data ingestion, training, evaluation, and deployment. Adapt and extend LLM models with fine-tuning, distillation, retrieval systems, and tool-use to solve domain-specific problems. Evaluate AI systems rigorously : Develop custom evaluations to ensure models succeed in real-world environments. Bring frontier methods into practice: Track the latest techniques in areas like RAG, tool use, multi-step agent orchestration, fine-tuning methods, and evaluation frameworks - and apply them to specific customer challenges. Collaborate across product and research : Partner with research and product teams to turn frontier techniques into production-ready features and workflows. Advance our core product : Encode the lessons from our customer engagements in our Mosaic product, consistently contributing reusable ML components, infrastructure abstractions, and performance improvements. What we're looking for AI-nativeness: You're excited about the potential for AI to transform businesses and want to play a hands-on role in bringing frontier technology into critical institutions. Strong ML foundations with hands-on experience building and deploying production models / AI systems. Being generative and collaborative: You love constantly jamming on new "what if" ideas with teammates and partners to bridge applied engineering, product, and research efforts. Extreme ownership : You're willing to jump in and love being the one on the hook. You aren't going to wait to be pointed at a task-you're going to identify what you think we should do next, and then do it. Execution excellence and speed : You can build stuff in messy environments and know how to get code written and shipped quickly. You can hold the balance of speed and quality and know when to push the pace vs. when to slow down. Customer-obsession and respect : You're motivated by understanding customer pain points and iterating directly with end users to deliver wins quickly. Bonus if you have Hands-on experience with LLM tooling (e.g., LangGraph, Mastra, Agents SDK). Experience fine-tuning, distilling, and deploying LLMs or other foundation models in production. Background in retrieval, RAG pipelines, or multi-step agent design (including tool use and human-in-the-loop systems). Strong engineering foundations in Python/TypeScript, cloud deployment (AWS/GCP/Azure), and modern MLOps/DevOps tooling. Prior startup or founding engineer experience, balancing craft, ownership, and speed.
We're working against an incredibly ambitious mission. It won't be easy, but it will likely be the most fulfilling work of your career. If this excites you, let's chat, even if you don't meet all of the qualifications above.
Our Values
Dream bigger: We have the unique privilege of taking on the most ambitious problems and we should chase them with optimism, responsibility, and genuine belief that we can make it happen. We have to embrace the hard things when no one else will.
Heart in the game: What we're doing matters and we have to give a shit. Internally, that means fixing badness when you find it. Externally, it means honoring the trust our customers place in us with their most important problems. This isn't a 9-5, nor is it a job we're ever going to monitor your hours. We promise to put work in front of you that matters and in return, we ask you to promise to care.
Win for the customer: Everyone is an engineer and the job of an engineer is to deliver outcomes, not outputs. Everything we do-the products we build, the partnerships we launch, the strategy we set-exists to make our customers successful. Delivery is the strategy.
Make the call: Organizations are only as strong as the pace at which they make decisions. Everyone at Percepta should feel empowered to commit and shape the ambiguity in front of them. But "make the call" cuts both ways: make the decision and make the phone call. High-agency decision-making only works with high-bandwidth communication and we commit to never operate in silos.
Intensity with kindness: We believe in excellence in execution, candor in feedback, ruthlessness in prioritization, and survivalist urgency. We also believe you don't need to be an asshole to deliver on any of this. The trust built through shared kindness and vulnerability is what makes the intensity sustainable.
