Senior Full Stack Engineer

Job Description

We're looking for a Senior Full Stack Engineer to build the internal products that run our e-commerce business — the tools our operations, finance, and growth teams use every day to manage brands, inventory, PPC, and marketplace performance. You'll own features end to end: shaping the solution together with the teams who will actually use it, building both the backend and the interface, shipping it, and keeping it healthy in production.

Responsibilities

• Design, build, and ship full-stack features end to end — from database schema to the interface people actually click
• Work closely with the product manager to turn messy, half-defined problems into scoped, shippable solutions — and go straight to the operations, finance, or growth teams when you need to see how the work actually gets done
• Improve and extend the internal services we already run — and build new ones from scratch when a problem deserves its own product
• Own your services in production — monitoring, performance, reliability, and fixing things when they break
• Contribute to architecture decisions and help evolve our codebase, tooling, and CI/CD
• Review code and raise the engineering bar through pragmatic standards and experience sharing
• Keep technical debt honest: refactor what slows the team down, ship what moves the business

Qualifications

Must have

• Strong Python — typing, testing, async, real production services
• Clean architecture instincts — you can walk us through a system you designed and explain its trade-offs
• Deep database knowledge — modeling, indexing, query optimization; comfortable in both OLTP and analytical worlds
• Docker & Kubernetes in production, not just tutorials
• GitHub Actions CI/CD — you've built pipelines, not only used them
• Solid GCP experience — we run on GKE, Cloud Run, BigQuery
• React / Next.js — able to ship a full feature without a dedicated frontend dev
• AI-native workflow — you use coding agents daily and build serious harnessing around them: project instructions, custom tools/MCP, verification loops, CI gates. You direct AI with judgment and verify what it produces — you don't just prompt and paste
• Passion for the craft — you care about the product, push back with better ideas, and stay curious. AI is your leverage, not your replacement
• Upper Intermediate English — be able to hold a conversation with the team in English

Nice to have

• Airflow / dbt / data pipeline exposure
• Terraform / IaC
• E-commerce or Amazon ecosystem experience

Hiring Process

The entire process should take around 2-3 weeks.
