From Lightfield's posting. “We” and “our” refer to the employer.
Lightfield is reimagining CRM as a world model of a business. By learning from emails, meetings, and customer conversations, we’re building a living understanding of how a company works—so AI can help teams anticipate what comes next, make better decisions, and take action.
More than 5,000 companies have used the product since its November launch. We’ve raised more than $70M from Andreessen Horowitz, Coatue, Maverick Ventures, and Greylock to attack the biggest software category in the world. We previously built Tome, which reached more than 25 million users, and our team brings experience from Llama, Instagram, Google, and Salesforce.
If you want to be part of the AI wave and are drawn to the systems challenges of a product used by both people and agents, this role is for you. Lightfield's infrastructure supports human-interactive requests, agent-driven queries and actions, scheduled agents, and continuous ingestion of email, calendar, and meeting data. Based in our Cambridge office, you'll work on the databases, scheduling, permissions, and distributed systems that keep these workloads fast, isolated, and reliable as they share the same underlying customer data.
The work is not research, but many of the same habits matter: forming hypotheses, reading unfamiliar systems deeply, designing careful experiments, and explaining what the evidence shows. You'll use those habits on problems like these:
Querying a schema-flexible data model.
Customers define their own object types, fields, and relationships at runtime, while the underlying data is stored in Postgres. We work on query planning, indexing, and data-access patterns that keep those records fast to filter and aggregate as datasets grow.
Record-level permissions across relationships.
Access can come from ownership, direct grants, group membership, or inheritance from another record. We need a permissions model that evaluates those paths efficiently and produces the same answer across the application, API, search, dashboards, and agents.
Balancing real-time and batch workloads.
Search indexing competes with historical imports and backfills for shared database and queue capacity. We use concurrency controls, prioritization, and backpressure to keep real-time updates moving while still processing large batches.
You'll design and review systems, debug production behavior, and gradually take full ownership of one or more subsystems. You'll ship production work early with close design and code review, then take on increasingly open-ended projects as you demonstrate readiness.
You'd join a small, systems-focused engineering group in our new Kendall Square office early enough to help establish how it works, alongside a site lead who is one of our most senior infrastructure engineers.
