The engineer will have direct founder access and substantial responsibility for decisions that shape the growing engineering team.

Responsibilities

\- Build and scale data-capture workflows across Next.js web applications and Python desktop systems.
\- Improve reliability, throughput, and performance under heavy production loads.
\- Architect data pipelines and make greenfield decisions about storage, caching, search, and message queues.
\- Establish engineering practices and scalable system patterns.
\- Work directly with the founders on product strategy and ship features quickly.
\- Take ideas from design through production and balance delivery speed with reliability.

Requirements

\- Full-stack JavaScript/Next.js and Python application development.
\- Strong coding fundamentals in Node.js/TypeScript, Python, and/or Go.
\- Serverless architecture and cloud functions for substantial data processing on AWS or GCP.
\- Distributed systems, scalability, system design, and clear reasoning about technical trade-offs.
\- Hands-on experience with Redis caching, Elasticsearch indexing, and Kafka, RabbitMQ, or comparable message queues.
\- Familiarity with Kubernetes, APIs, and NoSQL databases.
\- Evidence of personally getting ideas into production.
\- An active GitHub showing sustained building.
\- Ownership of production systems with measurable reliability or throughput results.
\- Experience with both user-facing software and demanding data infrastructure.
\- Proactive decisions in ambiguous, fast-moving startup work.
\- Clear motivation to work in AI operations and at an early-stage company.
\- Willingness to work the intense hours described in the hiring brief.

Preferred

\- AI research, LLM evaluation, or human-in-the-loop systems.
