Job description

Full-Stack Developer (React / Tailwind · Node.js · Go)

Contract · 3 months · Aug – Oct 2025 · Remote (Poland / Germany preferred) English B2–C1 required

1. Stack Overview

Layer

Tech

Purpose / Rationale

Front-end

React + TailwindCSS

Rapid UI iteration, utility-first styling, consistent theming

API / BFF

Node.js (TypeScript)

Auth, rate-limiting, session mgmt; shared TS types with UI

Micro-services

Go

High-performance, simple concurrency; rewriting legacy .NET

Cloud & Realtime

AWS ➜ GCP (planned) · Firebase (Auth, Firestore, Functions)

Decouple hosting from realtime data; smooth provider migration

Using Node.js as a gateway and Go for heavy workloads is a proven pattern (e.g., Stripe, Uber, Netflix).

2. Key Responsibilities

• Modernise legacy .NET micro-services into well-tested Go services (gRPC / REST).

• Build & own a TypeScript Node.js API gateway (Express or NestJS) that fronts Go services and Firebase.

• Craft polished UIs with React (hooks, SWR/React-Query) and TailwindCSS.

• Optimise SQL queries ( PostgreSQL) and model data in Firestore.

• Integrate RabbitMQ (or Pub/Sub) for event-driven communication between Go and Node layers.

• Configure Docker-based CI/CD; deploy to AWS (ECS + RDS) and blueprint the GCP migration (Cloud Run / GKE).

• Implement auth flows with Firebase Auth (email, social OAuth) and optional magic-link.

• Write automated unit, integration, and e2e tests (Go test, Jest, Playwright/Cypress).

• Embed security best practices (OWASP, GDPR) and participate in code reviews & cost-optimisation.

• Instrument & monitor services (OpenTelemetry, Grafana / Cloud Monitoring) to meet SLOs.

• Document APIs (OpenAPI / Swagger) and contribute run-books & ADRs.

• Collaborate in an Agile (Scrum / Kanban) setup—stand-ups, sprint planning, retrospectives.

3. Required Skills

4 + years professional backend development

Docker & CI/CD fluency; Git workflow mastery

3 + years Go in production

Comfort in AWS and GCP; Terraform or Pulumi a plus

3 + years React (functional) & Tailwind

Experience with RabbitMQ / Pub-Sub / SQS

2 + years Node.js (TypeScript) API work

Solid SQL ( PostgreSQL) & Firebase (Auth, Firestore)

Proficiency writing automated tests

English proficiency B2–C1

4. Nice-to-Have

• Kubernetes (EKS / GKE) or other orchestration

• Observability stacks (Grafana, Prometheus, Stackdriver)

• Exposure to AI/ML data pipelines

5. Perks

• Remote-first culture & flexible hours

• Dedicated PM for day-to-day support

• Opportunity to modernise and scale a high-impact mentorship platform

6. How to Apply

Send (1) CV / résumé, (2) GitHub or portfolio link, and (3) a short note on your most relevant Go + React project to your−recruiting−emailyour-recruiting-email with the subject line “Full-Stack Dev – Aug 2025.”
