Informacje o stanowisku

Hi there,

At Web Impact , we’re more than just an email marketing agency and digital solutions provider. We’re building cutting-edge, socially impactful products that redefine how businesses operate in the digital world.

We’re looking for a Senior Fullstack Engineer - a seasoned developer who thrives on building complex SaaS products, internal platforms, and automation-driven applications. You’ll work across the stack: from elegant frontends to scalable backends, from API integrations to deployment pipelines.

If you’re the kind of engineer who can see the whole system , challenge architecture decisions, and still deliver production-ready code, you’ll feel right at home here.

What You’ll Do

• Own and deliver end-to-end features for SaaS products and internal applications.

• Build and scale frontends (Next.js) and backends (Node.js, Nest.js).

• Design and integrate APIs (REST, gRPC, WebSockets), handling real-world complexity (rate limits, retries, auth flows).

• Collaborate with Product Managers and engineers on architecture and technical direction .

• Shape automation features that reduce manual work across the company.

• Work with databases (PostgreSQL, Clickhouse) for data modeling, analytics, and performance tuning.

• Ensure quality through code reviews, automated testing, CI/CD pipelines, and observability.

• Act as a senior reference point in the team - share knowledge, support less experienced developers, and help maintain high engineering standards. You’ll report directly to the Head of Frontend Engineering.

What We’re Looking For

• 5+ years of professional full-stack development experience (preferably in SaaS).

• Strong expertise in Next.js and React.js - production-grade apps, design systems, performance optimization.

• Solid backend engineering skills with Node.js (Nest.js a plus).

• Track record of building and maintaining scalable SaaS platforms or internal tools.

• Deep understanding of API integrations and distributed system patterns.

• Good knowledge of PostgreSQL / SQL .

• Familiarity with CI/CD pipelines and cloud environments (AWS, Vercel, DigitalOcean).

• Nice to have: event-driven architecture (RabbitMQ, Kafka, Redis Streams), and experience with Supabase

• Strong communication skills - able to explain technical trade-offs to engineers and Product Managers.

• Fluent in English and Polish .

Our Tech Stack

• Frontend: React.js, Next.js

• Backend: Node.js, NestJS, Golang, Elixir

• Messaging & Queues: RabbitMQ (LavinMQ), Redis Streams, Kafka

• Data: PostgreSQL, BigQuery, Clickhouse

• Infrastructure: AWS, Vercel, DigitalOcean, Fly.io, Google Cloud

• CI/CD / Git: Gitlab with Gitlab CI

• AI/ML & Automation: Proprietary GenAI models, integrated ML pipelines, orchestration tools

• Integrations: REST, gRPC, WebSockets, external APIs with rate limits

Why Join Us?

• Work on complex, high-scale SaaS applications that few companies dare to build.

• Ownership from day one - influence architecture, technology choices, and product direction.

• Collaborate with world-class engineers, AI specialists, and PMs.

• Innovation-first culture - explore cutting-edge frameworks and architectures.

• Competitive senior-level compensation and career growth.

• Social impact - contribute to automation products that empower businesses and communities.
