We are seeking a Backend Engineer to join our cross-functional feature teams, working on our future Digital Portals Experience. This initiative is a key part of our journey toward product-centric, outcome-driven digital solutions, inspired by LeSS (Large Scale Scrum) principles.
In this role, you will primarily focus on designing and implementing APIs and integrations, contributing to a modern microservices architecture that powers a seamless customer experience. You'll collaborate closely with senior engineers and other team members to deliver features while continuously learning enterprise-grade engineering patterns.
As part of a growing team, you'll have a voice in shaping both technical foundations and the culture of collaboration within and across teams.
While backend engineering is your primary focus, we value T-shaped profiles. Ideal candidates can or are willing to grow toward full-stack delivery (Next.js, React, Tailwind) when needed, this will help future-proof our teams and enable greater flexibility.

Participate in code reviews, design sessions, and knowledge-sharing forums
Assist with resolving production issues and improving service performance
Collaborate in cross-functional, product-aligned teams, owning shared outcomes
Contribute to continuous improvement, helping evolve engineering practices and team ways of working
Requirements
Strong foundation in backend development using Node.js
Understanding of API development concepts and application architecture
Knowledge of databases, queries, and schema management
Debugging skills, with a structured approach to problem-solving
Ability to collaborate effectively and demonstrate curiosity for continuous growth
Strong written and spoken English communication skills
NICE TO HAVE Requirements
Experience with NestJS framework and ORMs like Prisma
Familiarity with Redis and basic caching strategies
Full-Stack Capability:
Frontend development using Next.js, React, TypeScript
Experience with UI libraries (Tailwind CSS, Radix UI)
Exposure to messaging systems (e.g., RabbitMQ, Kafka)
Awareness of cloud and container platforms (AWS, Docker)
Background in e-commerce or digital customer platforms
Knowledge of observability tools (monitoring, logging, tracing)
Experience
2+ years professional experience in backend development
Practical experience with Node.js in production environments
Familiarity with TypeScript, or strong commitment to learn it
Experience building and consuming REST APIs
Solid understanding of SQL and relational database fundamentals (PostgreSQL preferred)
