About Lightfield Lightfield is an AI-native CRM that assembles itself from your email, calendar, and meetings. It captures every interaction and turns it into organized context: accounts, tasks, follow-ups, and insights, so nothing slips through the cracks. We’re rethinking CRM from first principles. Instead of forcing teams to maintain rigid systems, Lightfield learns from how companies actually work, adapting, automating, and surfacing the insight that drives growth. We’re building the CRM platform we always wished existed: fast, intelligent, and genuinely helpful. We are backed by Greylock, Lightspeed, and Coatue, and our founders previously built Tome, a generative AI presentation product used by over 25 million people. Before Lightfield, our team worked on Llama, Instagram, Facebook Messenger, Pinterest, Google, and Salesforce.
About
the role We’re looking for a driven, creative engineer who is excited about the challenge of leveraging LLMs to build exceptionally innovative product experiences. You’ll join us at the frontier of AI product development, developing industry-leading approaches to solve important customer problems. Engineers at Lightfield own and drive projects from inception to impact, working with teammates of all functions along the way. You’ll also push our company’s overall product and technical vision as we learn from each project and continue to scale.
What you'll do Collaborate with product leaders to identify customer problems, scope
requirements, and implement LLM-powered solutions. Apply LLMs as reasoning engines to build domain-specific AI assistants. Create and enhance prompts, applying techniques like few-shot learning and chain-of-thought. Develop and optimize end-to-end RAG pipelines and agent architectures to leverage public and proprietary data. Improve end-to-end AI agent quality (e.g. relevance, fidelity, latency) via empirical evaluation and iteration. Build and enhance systems and tools that enable high-velocity experimentation (e.g. LLM-powered automated evaluation) and customized product experiences. Stay at the forefront of AI research and incorporate state-of-the-art techniques. Shape technical direction and best practices for AI application development at Lightfield. Help build a world-class engineering team by recruiting and mentoring teammates.
Who you are You have the ability to ramp quickly on tech stack that features TypeScript, React, Next.js, Node.js, Apollo GraphQL, and Aurora PostgreSQL. You have explored working with LLMs, either through professional projects or personal experimentation. You have a degree in Computer Science or a related field, with a strong foundation in software engineering principles. You are familiar with AI and ML concepts (e.g. training, evaluation techniques). You are passionate about keeping up with and exploring the latest advancements in LLMs and LLMOps (including open source solutions, e.g. LangChain). You are excited to develop new best practices in an emerging domain. You can drive a project with an ambiguous problem independently. You enjoy strategically balancing ambitious vision with frequent delivery of user value. You are able to clearly communicate your reasoning and decisions to your teammates (technical and nontechnical) at an appropriate altitude of detail. You are energized by building software experiences customers will use directly and depend on to do their jobs successfully.

Lightfield is an AI-native CRM built for the modern era, designed to replace legacy tools like Salesforce and HubSpot by assembling itself automatically from a team's email, calendar, and meetings. Founded with the mission to become the definitive system of record for the AI era — just as Salesforce defined the cloud era — Lightfield is rethinking CRM from first principles: instead of forcing teams into rigid systems, it learns from how companies actually work, adapting, automating, and surfacing insights that drive growth. The company is backed by top-tier investors including Greylock, Lightspeed, and Coatue, and its founders previously built Tome, a generative AI presentation product used by over 25 million people. The team brings deep pedigree from Llama, Instagram, Facebook Messenger, Pinterest, Google, and Salesforce. Traction has been exceptional: over 3,000 companies have signed up for the product, with more than 100 new sign-ups every week and roughly 30 converting to paying customers weekly. Customers include notable names like Substack and Distill. Lightfield operates a dual go-to-market motion — a high-velocity self-serve PLG funnel paired with a direct sales motion targeting Series A/B startups — and is scaling rapidly with plans to grow its sales team from 1 to 7 AEs by end of year. The culture is high-intensity, mission-driven, and in-office four days a week, attracting missionaries over mercenaries who are genuinely excited about building a category-defining company.
