Generalist who's been the secret weapon on every team you've joined? This is the role.

You'll work across everything: agents, data infrastructure, product, and whatever the mission demands this month. The ceiling on this role is wherever you take it. What you'll own Whatever matters most right now - agent workflows, search and scraping infrastructure across a dozen-plus countries, underwriting models, customer-facing product The full loop - prototype fast, prove it with real customers, then harden it into production Your own trajectory - MTS here has grown into engineering leadership, AI leadership, and staff-level IC paths. The role becomes what your work earns.
