🎯 Who is this job for?

This role is best suited for a Mid-Level Full Stack Engineer with 1–3 years of experience who is comfortable working across frontend (React, Vue, or Angular) and backend (Node.js, TypeScript) and enjoys building scalable, well-structured applications. It fits someone with solid JavaScript fundamentals, experience with SQL/NoSQL databases, cloud platforms, and modern development practices like testing, CI/CD, and agile workflows. The position will appeal to engineers who want to grow fast in a product-focused environment, take ownership end to end, collaborate closely with non-technical stakeholders, and contribute to systems that prioritize performance, reliability, and real-world impact.

💬 Potential Interview Questions

What front-end technologies are you most comfortable with, and which do you prefer for new projects?
I’m most comfortable with React and TypeScript for new projects, but I’ve also worked with Vue and vanilla JavaScript where needed, always focusing on component-driven architecture, performance, and maintainability.
How do you typically design and build backend services with Node.js and TypeScript?
I start by defining clear API contracts (OpenAPI/GraphQL schema), organize code into modules (routing, controllers, services, repositories), use TypeScript for strict typing end-to-end, and follow SOLID and clean architecture principles so the business logic is decoupled from frameworks.
What is your experience with SQL and NoSQL databases?
I’ve designed schemas and written complex queries in PostgreSQL/MySQL, and used NoSQL stores like MongoDB/Redis for document and cache use cases, focusing on proper indexing, query optimization, and data access layers that hide DB specifics from the rest of the app.
How do you ensure frontend performance, accessibility, and responsiveness?
I use responsive layouts (Flexbox/Grid), code-splitting, lazy loading, memoization, image optimization, and browser dev tools/Lighthouse; for accessibility I follow semantic HTML, ARIA where needed, keyboard navigation, and color-contrast checks.
What is your approach to testing across the full stack?
I write unit tests for pure logic (Jest/Vitest), component tests for UI (React Testing Library), and end-to-end tests (Playwright/Cypress) for critical flows, integrate them into CI, and aim for a good balance of coverage vs. speed instead of testing everything at the same level.
Describe your experience with cloud platforms and CI/CD.
I’ve deployed Node/React apps to AWS/Azure using Docker and services like ECS/AKS or serverless functions, and set up CI/CD pipelines (GitHub Actions/GitLab CI) that run tests, build artifacts, and deploy to staging/production with environment-based configs.
How do you handle integrating third-party APIs and services (auth, payments, analytics, etc.)?
I wrap integrations in dedicated service modules, validate and sanitize all external data, handle rate limits and retries, and centralize error handling and observability (logging/metrics) so we can debug issues without leaking implementation details into the rest of the codebase.
Can you give an example of debugging a tricky production issue end-to-end?
In one case, a sporadic timeout only on mobile came from a combination of slow DB queries and an aggressive frontend polling interval; I used logs/metrics to trace the path, added DB indexes, adjusted polling and caching, and added alerts so we’d catch similar patterns early.
How do you collaborate with product managers and designers in an agile environment?
I join refinement/planning to clarify requirements, break work into small deliverables, propose technical trade-offs, share early UI prototypes, and keep communication async-friendly (tickets, docs, PRs) so everyone can follow progress and give feedback quickly.
Why are you interested in joining Metrikflow as a Full Stack Engineer?
I like that Metrikflow combines modern web tech (Node.js, TypeScript, modern frontends, cloud) with a clear climate-tech mission; it’s a chance to build scalable, high-quality software while contributing to the sustainability transition in a remote-first, international team.

📋 Job Summary

This position is a strong match for a junior–mid full-stack engineer based in Germany who wants to work in a remote-first, impact-driven climate tech startup, and is comfortable owning both frontends in React/Vue/Angular and backend services in Node.js/TypeScript with SQL/NoSQL. You’ll fit well if you enjoy designing and scaling web apps end-to-end (REST/GraphQL APIs, auth, payments, integrations), care about clean, tested code and CI/CD, and have some experience with cloud platforms (AWS/Azure/GCP), containers, or microservices, while being motivated by contributing to ESG and net-zero initiatives in a small, international team.
