Senior Full-Stack Engineer (TypeScript/Go)

## About Us
Smirnov Labs is a fast-growing engineering company founded by an ex-Googler. We help product teams launch and scale quickly by leveraging modern technology and AI-assisted development.
Our projects are diverse — we partner with clients at the earliest stages and own the technical delivery end-to-end.
We're a small, senior-heavy team where every engineer has real impact. No bureaucracy, no hand-holding — just sharp people shipping fast.
You'll work in our team, on codebases we own, making the technical calls yourself. Your time splits between client products we build end-to-end and our own internal products.
## The Stack

• **Backend** — TypeScript is our centre of gravity, with Go on the projects that call for it. We choose the framework per engagement rather than forcing a house standard.
• **Data** — Postgres almost everywhere. Cloud depends on the client (AWS, GCP).
• **Frontend** — React + TypeScript.
• **Infra** — Docker and your own deploys. We have no dedicated DevOps team.
• **AI** — LLM application work is a regular part of our client projects: retrieval pipelines, embeddings, agentic workflows.

## What You'll Do

• Own backend services end-to-end — architecture, implementation, deployment, and what happens when they break.
• Write mostly TypeScript, and Go where the project calls for it. Different engagements make different choices; you'll be comfortable in both.
• Design data models, schemas, and APIs on Postgres — and know when the database should be doing the work.
• Build the React/TypeScript frontend for the features you ship. You take a feature all the way through the UI, not just to the API boundary.
• Ship your own work to production: Docker, CI/CD, environments. There's no DevOps team to hand it to.
• Build LLM-backed features on real client products — retrieval, embeddings, agentic workflows, Claude and similar APIs.
• Make the technical decisions. Pick the framework, shape the architecture, choose the tradeoffs, and defend them in review.
• Move between projects — client products and our own — across different domains and constraints.
• Talk directly to clients and to the founder. No layers in between.
• Use AI-assisted development tools (Claude Code, Cursor, GitHub Copilot) as part of your daily workflow.

## What We're Looking For

• 6+ years building and running production backend systems
• Deep TypeScript on the server, not just in components — you know where the type system earns its keep
• Production Go experience, or enough depth to get there quickly — some of our projects are Go and you'll be expected to work in them
• Strong Postgres: schema design, query performance, migrations
• Solid React and TypeScript on the frontend — enough to build and ship a complete feature without a frontend engineer alongside you
• API design experience (REST, gRPC, or GraphQL) and an opinion on when to reach for which
• Comfortable owning your own deployments — Docker, CI/CD, cloud environments (AWS or GCP)
• A track record of shipping without a detailed spec and without process handed to you
• Comfort working in the US timezone (overlapping working hours required)
• Upper-Intermediate or higher English
• Ability to own and drive features independently with minimal supervision

**Nice to have**

• Hands-on experience with vector search and embeddings — pgvector, Qdrant, Pinecone, whatever you've used. Side projects and weekend experiments count; commercial experience is not required here.
• Experience building on LLM APIs — RAG, tool use, agents, evals.
• Depth in more than one backend language or ecosystem.
• Early-stage or agency background: greenfield work, shifting requirements, direct client contact.

## What We Offer

• Competitive salary above market average
• Fully remote work
• Flat structure — you talk directly to the founder and to clients, no middle management
• Real technical ownership: you make the architecture decisions on the systems you build
• Diverse and technically challenging projects
• Modern AI-powered development workflow
• Small team culture — your voice matters, your code ships
• Paid vacation and sick leave
• Flexible schedule within the US timezone overlap
• Professional and career growth through real ownership, not courses and certificates
