We are building JLL’s internal AI platform: the layer every team in the firm uses to ship AI agents and AI-backed products. That means a gateway that puts a large and growing set of models from multiple providers behind one API, a shared chat surface that makes any agent reachable by employees across the firm, the developer tooling that takes an agent from an idea to something running in production, etc.
Dozens of applications across JLL already run on the platform, with more being moved onto it. When one of the teams behind them gets stuck, whether it is an expired token deep inside an agent run, a model call failing at the gateway, or an MCP server that works locally and not in production, the engineers in these roles are the ones who get them moving again, and then make sure the next team never hits the same wall.
We are hiring Senior Software Engineers to own how the platform supports the teams building on it. This is a deeply technical role. The problems that reach you are the ones another team could not solve on their own, and they cross every boundary at once: identity, networking, cloud permissions, model APIs, MCP servers, agent runtimes, deployment.
The job is not to close tickets. It is to understand why a team’s agent environment is failing, fix it, and then remove the cause so the problem never recurs, through better diagnostics, better documentation, self-service tooling, or a change to the platform itself. Engineers in this role also ship features on the platform backlog.
