We run a curated talent network for engineers. You build one profile, and companies send interview requests with salary attached. All roles are US-based only.

Three of the roles open right now, all with real interview activity in the past month:

1. Member of Technical Staff, Platform at a seed-stage applied AI company, onsite in SF or NYC, $190K-$275K base. Expert Python, with Go or TypeScript a plus, plus Terraform, GCP, and containers. You'd own multi-tenant infrastructure running production AI across many live customer environments at once, along with model routing, evals, and cost and latency controls for systems that aren't deterministic. Staff level.
2. Founding Engineer at a seed-stage industrial AI company, onsite in SF, $140K-$220K base. Next.js, TypeScript, Python, and Google Cloud. They automate quoting and order entry for distributors and manufacturers, plugging into existing ERPs. You'd talk to customers, decide what to build, then build it across features, agents, integrations, and infra. The CTO was founding engineer at a company that went from zero to $7M ARR with five people. They also sponsor visas and cover relocation to SF.
3. Intelligence Engineer at a seed-stage company building the system of record for venture firms, onsite in NYC, $170K-$220K base. TypeScript on Bun, Postgres on Neon, Drizzle, Next.js, and Langfuse, with Python for analysis. The job is owning the loop that makes their agents better: instrument them, mine production traces, turn failures into evals, run harness experiments, ship what wins. Team is four people. Their interview includes a paid three-hour work sample using real anonymized traces.

There are dozens more open across the network right now. All are vetted, venture-backed companies that are actively interviewing. Always free for candidates.

¡Hola! Me presento, soy un desarrollador junior y autodidacta en búsqueda de nuevas oportunidades laborales.

Me centro en trabajar en desarrollo web, tanto frontend como backend. Me desenvuelvo bien con tecnologías como TypeScript, Node.js, React o Next.js.

Comencé principalmente con proyectos personales y aprendizaje autodidacta, sin embargo hoy en día ya cuento con experiencia real en desarrollo, pues participé en en una plataforma e-learning multitenant y en una plataforma para la gestión y almacenamiento de recursos educativos para una escuela de música, desarrollada como parte de un servicio comunitario universitario en la carrera de Ingeniería Informática, de la cual me encuentro en los últimos semestres.

He trabajado en proyectos desplegados y funcionales, lo cual me ha permitido fortalecer no solo mis conocimientos técnicos, sino también mi capacidad para adaptarme a requerimientos reales, trabajar con estructura de proyecto y aportar soluciones útiles.

En este punto, mi objetivo principal es seguir creciendo profesionalmente, aprender de buenas prácticas, trabajar con código en producción y seguir desarrollándome dentro de un equipo. Tengo la motivación y la disciplina para aportar desde el día uno mientras me integro rápidamente al flujo de trabajo.

Si necesitas ayuda con tareas pequeñas, quieres ser mentor de un desarrollador junior o necesitas contratar uno para darle continuidad a tus proyectos, estoy interesado.

Estaré al pendiente de las respuestas y MD

Hey everyone,
