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 job Lightfield is seeking a hands-on Infrastructure Tech Lead to help scale the platform through a period of rapid growth and increasing customer demand (and beyond!). After recently emerging from private beta, we’ve seen strong adoption from hundreds of businesses signing up each week, including larger, more mature teams using the product in production-critical ways. As customer scale and data volumes grow beyond initial expectations, the infrastructure is being pushed into a new phase. This role will be central to ensuring the platform remains fast, reliable, and resilient as Lightfield expands into larger enterprise use cases. This is not a “build a team immediately” role but instead, it’s a high-impact opportunity for an experienced infrastructure engineer to roll up their sleeves, own core scaling challenges, and help shape the long-term foundation of the system. What you’ll do Own and improve the reliability and performance of Lightfield’s infrastructure as customer scale accelerates Lead efforts to reduce database latency and optimize Postgres performance for large, high-volume workloads Strengthen operational maturity across the stack, including observability, incident response, and production readiness Build scalable systems and infrastructure patterns to support larger customers and increasing usage Partner closely with product and engineering leadership to prioritize the most critical infrastructure work at each stage of growth Help define the the longer-term infrastructure roadmap, with the opportunity to influence future team shape over time
Who you are 8–12+ years of experience building and scaling infrastructure and production systems in high-growth environments Deep expertise in infrastructure-heavy engineering (SRE, reliability, performance, scaling) rather than data pipeline–focused roles Strong hands-on coding ability and comfort owning critical systems end-to-end Experience with Postgres performance tuning, query optimization, and scaling database-backed applications Strong operational instincts: monitoring, on-call practices, debugging, and systems-level problem solving Product-oriented mindset — motivated by customer-facing performance and real-world reliability Comfort operating in ambiguity at an early-stage company, where priorities evolve quickly and ownership is high Why this role Lightfield is entering a key scaling inflection point: infrastructure built for early customers is now supporting much larger teams and more demanding workloads. This is a rare opportunity to join at the moment where foundational systems work will directly shape the next phase of growth.

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.
