Role Overview: We are looking for a forward-thinking Mid-Level Full Stack Developer to join an innovative project built on an AI-first architecture. The system has been developed over the past year using "Vibe Coding" principles, with the founder architecting the flow and logic using Claude.
 

We need a professional engineer who can bridge the gap between AI speed and human engineering rigor. You will work alongside the founder to build new features, fix bugs where the AI reaches its limits, and ensure the project remains scalable and stable.

Technical Stack:

• Frontend: Next.js (Expert level), JavaScript (ES6+).
• Backend: Node.js.
• AI Integration: Deep experience with Anthropic Claude 3.5, and specifically Claude Code (CLI) or Cursor Agent mode.
• DevOps & Infrastructure: Google Cloud Platform (GCP) and Coolify (managing logs and deployments via CLI).
• Environment: Docker/Containers (Essential for maintaining a stable environment for Claude Code).

Requirements:

• Education: Academic Degree (B.Sc. in Computer Science or Software Engineering) – Mandatory.
• Experience: 2-3 years of professional Full Stack development.
• AI Workflow: At least 1 year of hands-on experience using AI coding agents in your daily professional workflow. You must be comfortable with the "AI-Native" way of building.
• English: Fluent/Upper-intermediate. Excellent communication and responsibility are non-negotiable.
• Analytical Mindset: Ability to quickly understand existing logic, dependencies, and complex flows architected by AI.

Key Responsibilities:

• Collaborate with the founder to turn high-level AI-driven visions into production-grade features.
• Maintain and optimize the development environment using Docker to support Claude Code CLI.
• Identify and fix logical "hallucinations" or edge cases that AI tools might overlook.
• Manage deployments and monitor system health via Coolify and GCP.
• Refactor AI-generated code to maintain high architectural standards.

Why Join Us? This is not a traditional "coding by the book" role. You will be at the forefront of the AI development revolution, using the latest tools (Anthropic Claude Code) to build fast and smart. No corporate red tape - just pure building and innovation.

How to Apply: Please mention your experience with Claude Code or Cursor in your application and explain how you manage the balance between AI speed and code quality.

About the role You will build real-world AI applications for enterprise clients—from the initial concept straight through to production. As a Middle JavaScript Engineer at Upstaff, you’ll design, implement, and deploy high-quality solutions that solve genuine problems for real users. You’ll skip the heavy bureaucracy, work directly with clients and the product team, ship code to production within days, and collaborate with a team that values accountability and a thoughtful approach.

Responsibilities

• Develop and deploy full-fledged AI applications based on our core enterprise platform.
• Collaborate closely with clients and internal teams to customize and adapt AI solutions.
• Expand the platform's capabilities and enhance the UI/UX layers to meet modern standards.
• Integrate third-party APIs and internal tools to ensure seamless and secure data flow.

We're building AI-powered tools for the trades — HVAC, plumbing, electrical, and more. Our platform connects technicians in the field, customer service managers in the office, and homeowners in real time. We need a prompt engineer who can turn raw, messy, real-world conversations into structured intelligence that actually helps our customers run better businesses.

What you'll work on

• Transcript analysis. Design prompts that analyze real conversations between technicians, CSMs, and homeowners — surfacing what went wrong, what worked, and how to improve.
• Internal document intelligence. Build bots that read company SOPs, training docs, and service guides — then generate summaries, best practices, and recommendations.
• LLM evaluation. Test and benchmark multiple models (GPT, Claude, Gemini, and others) to find the best fit for each use case in our stack.
• Prompt architecture. Write structured, reusable prompts with dynamic context injection, persona framing, and clean output formatting for real business workflows.
• Continuous iteration. Evaluate real outputs against business goals, identify failure modes, and refine prompts based on actual field usage.

What we're looking for

• Hands-on experience with AI models (GPT, Claude, Gemini, Mistral, or similar) — not just using them, but understanding why they behave the way they do
• Ability to design prompts for multiple task types: classification, summarization, QA, recommendations, and structured extraction
• Strong written English — you write prompts for a living, so clarity and precision are non-negotiable
• Comfortable working with messy, unstructured inputs — real field conversations aren't clean
• Self-directed and proactive — you spot gaps before being asked and bring solutions, not just problems

Nice to have

• Background in or exposure to the home services / field service industry (HVAC, plumbing, electrical, pest control, etc.)
• Familiarity with ServiceTitan or similar field service management platforms

- Working knowledge of Python for backend services and pipeline glue code.
- Experience building UIs with modern frontend libraries (React and component kits such as AntD, MUI, or similar).
- Understanding of REST API principles and how to design clean HTTP interfaces.
- Experience working with WebSockets (or similar) for real-time data delivery to the UI.
- Familiarity with video/camera streaming protocols — RTSP, WebRTC, or HLS — and the basics of how frames move from a camera to a backend.
- Experience with relational and/or non-relational databases.
- Experience integrating with third-party systems and APIs.
- Understanding of Git beyond basic commits (branching, rebasing, resolving conflicts, working in feature branches).
- Basic knowledge of web security (auth, input validation, common vulnerabilities).
- Experience with AWS (S3, Lambda, SQS, CloudWatch) or equivalent services from other cloud providers.

Will be a plus:
- Experience with computer vision basics or OpenCV-style frame processing.
- Exposure to ML model integration (calling inference services, ONNX, TF Serving, or similar).
- Proficiency in Docker (writing simple Dockerfiles, Docker Compose, reading logs, local compose setups).
- Experience with message queues or streaming platforms (Kafka, Redis Streams, RabbitMQ).
- Familiarity with Serverless architecture.

Responsibilities:
- Work alongside a senior developer to build a pipeline that ingests camera streams, passes frames through ML inference, and surfaces results in a web UI.
- Write clean, maintainable, and efficient code following SOLID/DRY and team standards.
- Build real-time UIs that visualize streaming data — live video, detections, charts, overlays, and dashboards.
- Implement backend services in Python to handle stream ingestion, orchestrate ML calls, and expose APIs to the frontend.
- Integrate with external services and APIs with proper auth, retries, timeouts, and error handling.
- Design and maintain database schemas, indexes, and migrations; optimize queries where it matters.
- Diagnose, reproduce, and fix bugs across the stack.
- Create and maintain documentation.
- Participate in code reviews and architectural discussions; propose improvements.
- Join team ceremonies and planning.
- Ensure data security and help mitigate vulnerabilities.
- Optimize server and application performance, especially around streaming and real-time data paths.

We offer: 
- Work in a fast-paced, dynamic, and innovative business environment.
- Opportunity to directly influence the company's strategic IT architecture and products that scale globally.
- Access to modern tools, technologies, and in-house expertise.
- Flexible approach to project delivery and freedom to choose optimal technical solutions.
- Performance-based bonus system tied to team results.
