Mev, Llc.
Senior Full-Stack Engineer (Backend Focus, Agentic AI)
Mev, Llc., Phoenix, Arizona, United States, 85003
Project Overview
Our client is building an AI-driven learning platform that transforms technical documentation (PDFs, presentations, technical manuals) into interactive courses with automated video generation and intelligent AI tutoring. The platform serves pharmaceutical, manufacturing, and R&D sectors where subject matter experts need to convert complex technical content into training materials without relying on traditional learning and development teams.
We are looking for a Senior Full-Stack Engineer with strong backend expertise to be responsible for core backend services and agentic AI workflow integration. You'll architect and implement event-driven systems that orchestrate multi‑stage AI pipelines (document extraction, content structuring, video generation), integrate external AI services, and build reliable job processing with checkpointing and error recovery.
This role requires strong full‑stack development skills with a deep focus on the backend, hands‑on experience in building or integrating agent‑based workflows, and familiarity with LLM‑based systems.

Job Highlights:
Cutting‑edge agentic AI application combining multiple AI services into cohesive workflows
Real‑world impact, helping technical experts create accessible learning content
Opportunity to work with OpenAI, Anthropic, and specialized AI services (document extraction, video generation)
Greenfield project with modern tech stack and architectural freedom
Team Composition: Architect, Software Engineer, Designer, QA Engineer, DevOps Engineer, BA, Delivery Manager
Responsibilities
Build backend services and APIs that orchestrate multi‑step workflows with checkpointing and error recovery
Design and implement agentic systems for course generation, chatbot functionality, and content processing
Operationalize prompts and LLM workflows designed by client‑side AI and instructional design experts
Integrate third‑party APIs (LLM providers, video generation) with proper rate limiting, retry logic, and cost monitoring
Implement secure authentication flows, RBAC policies, and tenant isolation using Supabase Auth and RLS
Write database migrations, design efficient schemas, and optimize queries for performance
Contribute to frontend development when needed to support full‑stack features
Integrate application‑level monitoring (Sentry) and analytics tools (Mixpanel/Amplitude/PostHog) with backend services
Participate in architecture decisions, code reviews, and sprint planning
Collaborate with the solution architect on technical design decisions
Work with DevOps engineer on deployment requirements and observability tooling
Partner with a frontend‑focused engineer on API contracts, data models, and full‑stack feature integration
Qualifications
5+ years of full‑stack development experience with a strong backend focus (Node.js, TypeScript)
Experience using AI‑powered productivity tools (Cursor, VS Code with Copilot, or similar AI‑enhanced IDEs) and LLMs for research and problem‑solving (ChatGPT, Claude, etc.)
Experience building or integrating agentic workflows or LLM‑powered applications
Hands‑on experience with LangChain, LangGraph, or similar orchestration frameworks
Familiarity with OpenAI and/or Anthropic APIs, prompt engineering, and structured output validation
Working knowledge of React and Next.js (able to contribute to full‑stack features when needed)
Solid understanding of PostgreSQL (schema design, migrations, query optimization)
Experience with event‑driven architectures, job queues (Redis/BullMQ, AWS SQS), and asynchronous processing
Familiarity with NestJS or similar backend frameworks (Express, Fastify)
Experience with authentication, authorization, and multi‑tenant data isolation patterns
Strong problem‑solving skills and ability to work autonomously with minimal oversight
Clear written and spoken English for async collaboration and documentation
Nice to Have
Experience with Supabase (Auth, RLS, Realtime)
Familiarity with LLM observability tools (Arize AI, Phoenix, LangSmith)
Experience with document processing pipelines or OCR integration
Knowledge of video generation APIs (Synthesia or similar)
Familiarity with error monitoring (Sentry) and product analytics tools (Mixpanel, Amplitude, PostHog)
Understanding of prompt engineering principles and best practices
Experience with evaluation frameworks for LLM‑generated content
Background in EdTech, content generation, or learning platforms
Familiarity with Tailwind CSS and modern UI development patterns
GitHub‑based workflows and conventional commits

Accounting services
Health insurance
$600 extra for the health care, sports or mental health
10 working days of sick leave
Professional Development $600/year you can spend on:
Improvement of qualification/ certification
[ our values/ ] What Keeps Us Sharp and Steady We cut the fluff and keep it real—owning our work, refining our craft, and always leveling up. No excuses, just a team that’s in it together, pushing boundaries and delivering results.
Pragmatic
Theory’s cute, but results pay the bills. Perfect’s a fairy tale—done right is what counts.
Adult
No drama, no sugarcoating. We own our wins and our screw‑ups, and treat failure like free tuition.
Craftspeople
We’re not assembly‑line coders. We build, we refine, and we don’t put a fresh coat of paint on bad code.
Falling behind? We leave that to others. Leveling up fast, chasing down answers, and never settling for “I don’t know.”
Great Allies
No lone wolves here. We listen before we talk, communicate like grown‑ups, and make the ride better for everyone.
Headquartered in the USA and Ukraine, but our team? We're everywhere. We’re fully remote, so you can work wherever you’re most productive.
