The posting
Empower our stores to drive B2B growth through a world-class Sales application
Join us as our new Senior Backend Engineer and come play a pivotal role in evolving the Sales application - the critical engine that enables all our stores to sell to B2B customers across the STARK Group.
You will join a team at the heart of our commercial digital transformation. In this role, you won’t just be writing code; you will be building the scalable architecture that allows our business to handle complex B2B sales flows, ensuring that our stores have the reliability and performance they need to serve professional craftsmen effectively.
You will blend deep hands-on engineering with architectural thinking, helping us transition from legacy constraints to a modern, composable, and cloud-native landscape.
What you'll be doing
You will take a senior role in the continued development of the Sales application, working closely with fellow engineers, architects and business stakeholders to turn complex B2B requirements into technical solutions.
Within your first 6–12 months, you will, among other things:
- Lead the design and implementation of robust backend services that power the B2B sales experience.
- Strengthen the system’s reliability and performance, ensuring a seamless experience for users in our stores.
- Evolve our microservice and event-driven architecture, including Kafka-based communication and integrations with core commercial services such as Pricing.
- Safeguard the long-term technical health of the application by championing clean architecture, SOLID principles, and rigorous testing.
- Mentor junior developers, conducting impactful code reviews and raising the overall engineering bar of the team.
- Ensure high data integrity and performance within our PostgreSQL databases.
What we offer
The Sales app is a cornerstone of STARK Group’s ability to compete and grow in the B2B market. By building a high-performance backend, you are directly impacting the daily work of thousands of employees and the experience of our professional customers.
Your work ensures that the transition from “legacy” to “modern” isn’t just a change in technology, but a leap in how the business can operate - enabling pricing agility, better margin visibility, and a superior sales flow.
Who we are looking for
You are an experienced backend engineer who thrives on solving complex problems and turning ambiguous business needs into structured, scalable code. You are a “technical leader by example” who cares as much about the maintainability of the code as you do about the feature delivery.
From a technical perspective, we expect that you:
- Have 5–10 years of professional experience in software development, with a strong experience in C# and the .NET ecosystem.
- Have a strong track record of building microservices and distributed systems in cloud environments (preferably Azure).
- Are experienced with event-driven architectures and have hands on experience with messaging systems (e.g., Kafka).
- Have deep knowledge of relational databases, specifically PostgreSQL.
- Are well-versed in engineering best practices, including Clean Architecture, DDD, SOLID, and automated testing.
- Have experience deploying and monitoring applications using Kubernetes, Argo, and Grafana.
In addition, it is an advantage if you:
- Have experience with B2B sales processes or large-scale e-commerce logic.
- Have a general understanding of AI integration within software development to improve productivity or feature sets.
- Have worked in a matrix organization within a large-scale digital transformation programme.
Overall, you bring a pragmatic approach to engineering. You care about building solutions the right way, while recognising that strong engineering is also about balancing technical quality with the need to deliver business value.
