Were representing a fast-growing AI and data infrastructure company building the systems that power frontier model development agentic workflows and complex AI training datasets. The company works with leading AI labs as well as rapidly scaling YC-backed startups helping them create the sophisticated data infrastructure required for advanced reasoning and AI agent development.

Founded in 2024 the company has raised approximately $34M and grown to roughly 40 employees. The team includes engineers and operators from highly technical organizations across quantitative trading and technology and the company is experiencing rapid growth as demand for frontier AI data infrastructure expands.

Theyre now building out their engineering presence in Latin America and looking for full-stack engineers who want founding-level ownership in a small fast-moving environment.

• Build and scale complex data-capture workflows across web and desktop environments.
• Develop customer-facing applications using JavaScript/TypeScript and Python.
• Own projects end-to-end from initial architecture and product decisions through implementation and production.
• Architect and optimize high-throughput data pipelines handling significant workloads.
• Build reliable infrastructure for capturing and processing data used in advanced AI and agentic workflows.
• Work across frontend and backend systems with a particular emphasis on building strong user-facing product experiences.
• Design systems using technologies such as Redis Elasticsearch Kafka or RabbitMQ and cloud infrastructure.
• Build and operate serverless and cloud-native systems across AWS or GCP.
• Collaborate directly with the founding team to define product strategy and determine what should be built.
• Move quickly from ambiguous requirements to working production software.
• Establish engineering patterns and best practices as the team grows.
• Use modern AI development workflows to accelerate engineering and product iteration.
• Take on increasing technical and organizational ownership as the engineering team expands.

• 410 years of professional full-stack software engineering experience.
• Strong production experience with JavaScript/TypeScript and Python.
• Strong experience with ideally building complex user-facing web applications.
• Full-stack engineer with particularly strong frontend/product engineering ability.
• Experience building and scaling complex data-capture workflows.
• Experience designing or optimizing high-throughput data pipelines.
• Background at a reputable rapidly growing startup rather than exclusively large-company environments.
• Proven ability to own meaningful projects from architecture through production.
• Experience with serverless or cloud-native architecture on AWS or GCP.
• Hands-on experience with technologies such as Redis Elasticsearch Kafka or RabbitMQ.
• Strong English communication skills and comfortable collaborating with U.S.-based teams.
• Comfortable inferring requirements and making decisions without highly detailed specifications.
• Stable employment history with enough tenure to demonstrate meaningful project ownership.
• Based in Latin America and able to maintain substantial overlap with U.S. working hours.

• Previous experience at an early-stage VC-backed or YC-backed startup.
• Founding engineer or early engineering team experience.
• Experience working directly with founders on both product and technical strategy.
• Strong GitHub profile demonstrating consistent hands-on engineering activity.
• Experience building infrastructure for AI data model training evaluations or agentic workflows.
• Experience supporting high-throughput or data-intensive applications.
• Familiarity with Kubernetes.
• Experience working for a U.S.-based company or within a U.S.-centric engineering culture.
• Computer Science degree from a strong technical university.
• Experience working across both web applications and Python-based desktop or backend systems.
• Strong product instincts in addition to technical execution.

• Base salary: $60000$90000.
• Competitive equity.
• Fully remote position for candidates based in Latin America.
• Expected to work primarily U.S.-aligned hours.
• Three planned hires for the team.
• Join a roughly 40-person AI infrastructure company with approximately $34M in funding.
• High-ownership environment where engineers are expected to own entire projects rather than narrowly defined tickets.
• Opportunity to grow into engineering leadership as the organization scales.
• Interview process includes a culture conversation technical screen paid system-design take-home and a two-day remote work trial.
• Best suited for engineers coming from high-growth startup environments rather than candidates whose experience is primarily at FAANG or other large technology companies.
• Candidates with repeated short tenures or primarily contract/project-based backgrounds are unlikely to be a fit.
