Software Engineer

About the role

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.

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

Minimum qualifications

• 3+ years shipping production code with end-to-end ownership of features
• Full-stack range across modern web (TypeScript, React, Next.js) and a backend language (Python or Node), with comfort across relational databases and a cloud platform (we use GCP)
• Working fluency with Claude Code or comparable agentic engineering tooling — used daily on real work, with the judgement to direct AI on multi-step tasks and identify when its output is wrong
• Strong async written communication: PR descriptions, design notes, written code reviews
• Direct comfort in front of a client: standups, demos, scoping conversations

Preferred qualifications

• Bilingual English / Spanish
• Production experience with Vertex AI, Gemini, or the Claude / Anthropic API
• Specific GCP depth (Cloud Run, Cloud Build, Vertex AI, IAM)
• Experience with agentic workflow tooling, MCP servers, or RAG systems in production
• Open-source contributions or production-grade side projects

What we offer

• Trust-based time off (minimum 4 weeks per year)
• Equipment stipend
• Annual learning and conference budget
• Health coverage per local market
• Career progression: most Software Engineers progress to Senior Applied AI Engineer within 18–30 months based on demonstrated capability
