About the role:
We are looking for a Full-Stack AI Platform Engineer to join our team and help build, maintain, and scale AI-powered interactive products.
This is a hands-on role for an engineer who owns deployment, infrastructure, real-time systems, and AI-service integration end to end. You will work on production systems that combine web applications, real-time communication, Kubernetes-based backend services, and GPU-hosted AI pipelines.
The core of this role is production reliability and deployment ownership — keeping live systems stable, responding to incidents, and integrating AI models into scalable real-time infrastructure. Frontend work exists but is secondary: the team has a designer and uses AI-assisted tooling for UI iteration.

Responsibilities:
- Own deployment, environment management, and release workflows across Kubernetes-based, Railway-hosted, and other cloud infrastructure.
- Respond to production incidents, perform rollbacks, and restore service stability, including outside business hours.
- Deploy and operate AI inference services on GPU platforms such as Modal or RunPod and integrate them into real-time product flows.
- Build and maintain real-time communication and async processing flows, including LiveKit-based session infrastructure.
- Work with TypeScript / JavaScript and Python application code in production environments.
- Support database-backed product features, schema evolution, and migration workflows.
- Improve observability, logging, monitoring, and incident debugging workflows.
- Contribute to frontend and backend product functionality as needed, using AI-assisted tooling where appropriate.
- Maintain clear and up-to-date documentation for every product, service, and integration, including architecture diagrams, API contracts, deployment procedures, and environment configuration.
- Ensure every new feature is discussed, scoped, and agreed upon before implementation begins. No undocumented or uncoordinated changes to production systems.
- Collaborate with engineering and product stakeholders to clarify requirements, identify risks, and ship practical solutions.

Required skills:
- Strong hands-on experience with TypeScript (Node.js) and Python for production backend development.
- Solid experience with Kubernetes, Helm, and container-based deployment workflows.
- Experience with real-time systems: WebSocket-based communication, session lifecycle management, and event-driven flows.
- Experience deploying and operating AI inference services on GPU platforms such as Modal, RunPod, Replicate, or similar.
- Experience integrating LLM-based services, voice AI APIs, or media-processing pipelines into production systems.
- Experience debugging distributed or multi-service systems, including reading logs across multiple services and environments.
- Comfort with production ownership: incident response, rollbacks, and on-call responsibility.
- Solid understanding of backend APIs, service integration, and system design.
- Experience with PostgreSQL and ORM-backed schema management and migrations.
- Sufficient frontend experience to ship and deploy UI changes with AI-assisted tooling.
- Ability to work independently and bring structure to ambiguous technical situations.
- Strong written and verbal English communication skills.
- Experience using AI-assisted coding tools (e.g., Cursor, GitHub Copilot, Gemini) for faster development and iteration

Nice to have:
- Hands-on experience with real-time audio/video systems such as LiveKit or similar platforms.
- Experience with avatar, video rendering, or real-time media processing pipelines.
- Experience with frameworks and tooling such as TanStack Start, Nitro, or Vite.
- Familiarity with vector databases or embedding-based retrieval (pgvector or similar).
- Familiarity with Python ML stacks such as PyTorch or CUDA-based GPU inference.
- Experience with voice AI pipelines involving services such as ElevenLabs or Deepgram.
- Experience with CI/CD pipelines such as Jenkins, GitHub Actions, or similar.
- Experience with Next.js and Nx monorepo environments.
- Experience with GraphQL / Apollo or similar API integration patterns.

What we value:
- Strong ownership and reliability, especially in production.
- Pragmatic engineering judgment: shipping something stable beats over-engineering.
- Comfort with production responsibility and debugging under pressure.
- Ability to move across backend, infrastructure, and frontend without losing clarity.
- Clear communication, honest estimation, and practical execution.
- Documentation discipline: if it is not written down, it does not exist.

What we offer:
- Real impact: your content will directly attract new clients.
- Mentorship and growth.
- Freedom to experiment and test new formats.
- Flexible schedule and a remote-first culture.

The product combines professional diagnostic tools, standardized treatment protocols, and integrated e-commerce capabilities to help salons and wellness centers deliver personalized, data-driven experiences to their customers.

The platform serves as an end-to-end system for head spa providers, enabling them to analyze scalp conditions, manage treatment workflows, and seamlessly connect services with product sales. The system is already in use and continues to evolve as the company expands its footprint globally.

The product is built with a modern full stack architecture using React and NestJS, running on AWS infrastructure. It includes integrations with third-party platforms like Shopify and Zoho, supports real-time data processing, and relies on a combination of relational and NoSQL databases. The team is small, highly focused, and operates in a fast-paced remote environment.

In this role you will act as a key technical contributor and take ownership across the entire product lifecycle, from architectural decisions to production support. This is not just an execution role, but a position with real influence on technical direction and product quality.

Responsibilities

• Work across the full stack using React and NestJS to build and maintain product features

• Own features end-to-end from design and architecture through deployment and support

• Manage and improve AWS infrastructure, including IAM (Cognito) and cloud services

• Develop and maintain CI/CD pipelines using GitHub Actions

This is an opportunity to join an early-stage, privately funded company as a foundational engineer, with real ownership over the product and direct impact on its evolution. As the company grows, both scope and compensation will scale accordingly.

The role is fully remote and requires strong English communication skills.

Our client is an AdTech SaaS built on Shopify that helps e-commerce businesses run ads on Meta and Google. The product is evolving from a simple setup tool into a full AI-driven solution: it analyzes a store, identifies the best product opportunities, generates creatives, launches campaigns, and optimizes them automatically. The merchant sets a target ROAS — the system handles the rest.

They are looking for a Senior Engineer who can take real ownership of the product and help deliver the next stage of growth.

What you’ll own

In the first months, you’ll dive deep into the existing platform: stabilizing, maintaining, and building context. Then you’ll move into:

• AI-native experience: building store intelligence that analyzes merchant data, scores products by predicted ROAS, and drives campaign decisions automatically
• Deep Shopify integration: ensuring the product lives where merchants already work (Shopify admin, Sidekick, Flow), not as a separate tool
• Platform reliability & UX improvements: improving onboarding, ROAS optimization, and performance transparency

• Quality at every stage: owning QA as part of delivery — writing specs with acceptance criteria, critically reviewing AI-generated code, and ensuring features are tested before release

   

How the team works

The team follows an AI-assisted development approach:
spec → generate → review → refine → ship

You don’t need to write every line manually — but you do need to:

• write clear specs
• review code confidently
• maintain a high quality bar

You’ll work directly with the founders — no PM layer, no excessive processes.

This role is for you if:

• You have 5+ years of production experience with Python and React
• You have hands-on experience with AWS (EC2, RDS, S3, Lambda or similar)
• You’re comfortable owning the full stack (frontend, backend, infrastructure)
• You’ve worked with Shopify API, Meta Marketing API, or Google Ads API
• You’re used to being the primary engineer and making architectural decisions
• You can balance support and feature development
• You’ve used AI coding tools (Cursor, Claude Code, Copilot) and understand their strengths and limitations

• You treat QA as part of shipping (tests, code reviews, validation before release)

   

Nice to have

• Experience building or maintaining Shopify apps
• Familiarity with LLM APIs (OpenAI, Gemini)
• Background in AdTech or performance marketing

What our client offers

• Real equity — joining as a key engineer at a pivotal stage
• Ownership over architecture and decisions
• Fully remote, flexible schedule
• Competitive salary
• Paid vacation
