Full Stack Engineer, Product & Systems

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 team previously built Tome, a generative AI presentation product used by over 25 million people. Before Tome, many of us worked on Llama, Instagram, Facebook Messenger, Pinterest, Google, and Salesforce.

About the role

We're looking for an experienced, creative, and versatile engineer who is eager to tackle the challenge of building scaled, performant features and systems that deliver exceptionally innovative AI product experiences.

At Lightfield, engineers take ownership of projects from inception to impact, collaborating across functions and pushing the envelope on what's possible in applied AI systems development. You'll work alongside a talented team to deliver industry-leading solutions and contribute to Lightfield product and technical vision.

What you'll do

• Collaborate with product leaders to identify customer problems, scope requirements, and implement solutions.
• Build and maintain full-stack product features and systems, end-to-end, ensuring reliability, scalability, and performance.
• Develop observability and metrics to enable smooth operation, proactive issue detection, and continuous improvement.
• Mentor teammates, participate in code reviews, and help shape engineering culture and practices.
• Contribute to building a world-class engineering team through recruiting, mentorship, and knowledge-sharing.
