About The Position

Sourcerer is hiring a Member of Technical Staff for exceptional builders who can take highly ambiguous problems and turn them into working systems. The role spans agents, data infrastructure, product, and other areas as the company’s mission requires. Examples of problems include underwriting suppliers in China and enabling an agent to negotiate a purchase order.

The position owns whichever areas matter most at a given time, including agent workflows, search and scraping infrastructure across more than a dozen countries, underwriting models, and customer-facing product. The role covers the full development loop: prototyping quickly, validating with real customers, and hardening successful solutions for production. The position’s longer-term trajectory may develop into engineering leadership, AI leadership, or a staff-level individual contributor path, based on the work delivered.

Requirements

• Exceptional technical ability, evaluated by what the candidate has built rather than years of experience.
• Serious experience with modern AI tooling such as LLMs, agents, and evaluations, and/or hard systems engineering.
• A high degree of agency: independently finding and solving problems.

Nice To Haves

• Former founder, research engineer, or a generalist who has been a key contributor across teams.
• Interest in joining a company at an early stage that already has real revenue and enterprise customers.

Responsibilities

• Build and own systems for high-priority company problems, which may include agent workflows, search and scraping infrastructure across more than a dozen countries, underwriting models, and customer-facing product.
• Take work through the full development loop: prototype quickly, prove it with real customers, and harden it into production.
• Identify important problems independently and solve them with a high degree of agency.

Benefits

• Competitive salary and early-stage equity calibrated to the candidate’s contribution.
• Health, dental, and vision benefits.
• A small team with substantial individual leverage and direct access to founders and customers.
