Engineering and Research

We are transforming the services economy with AI.
Long Lake acquires service business and transforms how they operate through a shared AI platform, forward-deployed engineers, and a world-class M&A / operations team.

We're backed by General Catalyst, Alpha Wave, Elad Gil, and others, with billions in permanent capital raised. We are not a private equity fund but a permanent capital vehicle with an extremely long-term view. In the words of Warren Buffett, "our favorite holding period is forever."

Most AI companies build demos. We build and run operating systems for real businesses. This is a rare chance to own the full arc: design the system, deploy it into production, watch operators rely on it every day, and iterate until it's irreplaceable.

Some engineers at Long Lake focus on our AI platform: agent orchestration, real-world evals, connectors, data infrastructure. Others spend more time embedded with portfolio companies, running discovery, shipping vertical tools, automating workflows and driving adoption.

Problems you might work on:

• Turning a workflow where someone spends hours copying data between systems, QA-ing outputs, and producing documents into a background agent that runs in minutes and flags exceptions for review

• Writing the integration between a modern agent and a legacy industry ERP with no clean API, and making it reliable enough to run core business operations

• Building the deployment infrastructure that makes rolling AI into a new business repeatable rather than bespoke: the orchestration, connectors, and reliability layer that every new workflow inherits

• Going onsite with a team, expanding adoption beyond the early power users, measuring impact, and shipping the changes that make daily use feel obvious

• Building the evals, feedback loops, and training pipelines that teach AI to reliably complete specific jobs, turning capable models into genuine AI coworkers

• You've shipped something into daily production use, not a pilot or a proof of concept, and the team would notice if it went down tomorrow

• A workflow that used to take a person hours now runs as a background agent, and the hours have been redirected to higher-leverage work

• Something you built once has been reused across multiple portfolio companies, because you designed for the second deployment, not just the first

• You can point to a specific business metric (throughput, cycle time, error rate) that moved because of work you led
