📋 Description

• Set technical direction and architecture for major areas of the platform, and bring the rest of engineering with you. • Own our hardest problems end to end: the ambiguous, cross-cutting, high-stakes work where the right path is not obvious yet. • Make the build/buy and architectural calls that shape the platform for years, and write down the reasoning so others can build on it. • Take cutting-edge language models into production inside enterprise customer workflows, where reliability and safety actually matter. • Multiply the team. Raise the engineering bar through design review, technical mentorship, and the standard you set by example. • Identify the technical initiatives we should be running, rather than waiting to be handed them. • Keep us honest on reliability, performance, and scale as we grow across channels and brands.

🎯 Requirements

• 7+ years of software engineering, with a track record of technical leadership across teams or systems. Years are a floor, not the signal. • Deep full-stack strength in our core stack: Node.js, React, TypeScript, Express. • Strong with AWS in production (Fargate, Lambda, EC2, SQS) and with PostgreSQL and Redis. • Fluent in microservices and distributed systems, and clear on when not to reach for them. • Comfortable owning CI/CD and infrastructure with a real DevOps mindset (CodePipeline, GitHub Actions, or similar). • Product-minded. You think in customer outcomes and business impact, not tickets closed. • You have shipped LLM-powered features to production. This is a must, not a bonus. You know what breaks when models meet real users at scale. • Direct, low-ego, high-ownership. You fix first and explain after, and you give and take honest feedback without flinching.

🏖️ Benefits

• Real ownership. You will own problems, not tasks, with the autonomy to solve them your way and the trust to do it without a manager in your inbox. • Work that ships and matters. What you build reaches real consumer brands fast. • A category we are creating. The Agent of Record is new ground, with unsolved problems and cutting-edge models, not a crowded field to compete in. • A team that respects your judgment. Globally distributed, async-first, low bureaucracy. We hire adults and treat you like one. • Great salary plus equity or stock grants. Own a piece of what you build. • Learning budget. If you are growing, so are we. • AI-fluency by default. Few places will push your work with production AI further or faster.
