About Thirdlayer
ThirdLayer is solving one of the hardest problems in deploying agents: AI models are generic, but people's work and processes are specific. Our product, Dex, embeds within your computer and team, ingesting a continuous stream of data across your browser and work apps to understand how you actually operate. So when you delegate tasks, agents know exactly the context of where information lives and how decisions get made. We're a deeply technical team with a high bar for talent and a shared belief that exceptional people are the foundation of everything we build.
The role
You'll be the person who makes our platform real for customers. You'll deploy our system into live environments, build the data pipelines and integrations that connect our agents to a customer's actual tools and workflows, and own the full lifecycle from scoping to production. This is a high-leverage role: you'll be the closest person to the customer, the first to understand what's working and what isn't, and the one who turns those insights into product improvements. We move fast but hold a very high bar for correctness, maintainability, and simplicity.
What you will do
- Deploy and configure our platform for new customers, mapping it to their specific workflows and processes.
- Build ETL pipelines, integrations, and tooling that enable agents to ingest and act on company-specific data.
- Work directly with customers to understand their operations, identify high-impact problems, and ship solutions.
- Own the feedback loop between customer deployments and the core platform, turning patterns into product features.
- Build and maintain connectors to external systems that customers rely on.
- Debug production systems, identify bottlenecks, and drive reliability improvements across deployments.
What we are looking for
- Strong fundamentals in at least one modern language (TypeScript, Python, Rust, Go, etc.).
- Experience building ETL pipelines, data integrations, or working with high-volume data systems.
- You're the kind of engineer who thrives when you're close to the customer and can see the direct impact of your work.
- Ability to turn ambiguous product asks into simple, pragmatic solutions.
- Familiarity with system design, engineering best practices, and debugging in production environments.
- Comfortable working across the stack, from APIs and orchestration to user-facing surfaces.
- Strong communicator who can earn trust with technical and non-technical stakeholders.
