Who we are
Momentous is an AI engineering company that designs, builds, and operates production AI systems for organizations across industries — from global technology companies and healthcare providers to government bodies and experiential agencies. Their work spans custom AI products, agentic systems, computer vision, knowledge platforms, and the infrastructure behind them, all grounded in a consistent methodology: discover the real friction, design the right solution, deliver with precision, and transfer full ownership to the client's team. Momentous doesn't create dependency — they transfer capability.
Our impact
At Momentous, impact isn't a side project — it's a founding commitment. Twenty percent of our engineering capacity is permanently allocated to sustainability and social impact work, written into our structure before we had a single paying client. That's what produced WasteLens, a computer vision platform helping restaurants and hotel chains across Latin America reduce food waste in line with UN SDG 12. These projects aren't charity — they're some of our sharpest engineering work. Building for communities with tight budgets and diverse users forces a precision that makes everything else we build better. When you join Momentous, one-fifth of your time goes toward work that matters beyond the bottom line. Non-negotiable, and it always has been.
Purpose of the Position
Momentous is hiring a Software Engineer to own end-to-end delivery on the production AI systems we build for our clients. Engagements span custom AI products, knowledge platforms, agentic systems, computer vision, and the infrastructure that runs them. You will own the work shipped under your name, pair with senior engineers on the more complex builds, and contribute to architectural decisions on the systems you build, alongside senior engineers.
Key Responsibilities
Own end-to-end delivery of features and projects: design, implementation, deployment, and the client conversation around them
Pair with senior engineers on complex builds, owning meaningful slices independently
Build production AI workflows: RAG components, integrations across cloud platforms, agentic automations
Review pull requests from associate engineers
Write design notes that the team uses; contribute to architectural conversations

Whether you're working with a client or a teammate, the relationship matters as much as the output.
