The company and our mission:
Zartis is a digital solutions provider working across technology strategy, software engineering and product development.
We partner with firms across financial services, MedTech, media, logistics technology, renewable energy, EdTech, e-commerce, and more. Our engineering hubs in EMEA and LATAM are full of talented professionals delivering business success and digital improvement across application development, software architecture, CI/CD, business intelligence, QA automation, and new technology integrations.
We are looking for a Senior Software Engineer to work on a project in the fashion industry.
The project:
Our teammates are talented people that come from a variety of backgrounds. We’re committed to building an inclusive culture based on trust and innovation.
You will be part of a distributed team developing new technologies to solve real business problems. Our client is a leading premium fashion and lifestyle omnichannel retailer, with a long heritage and a strong digital commerce presence alongside its physical stores. The organisation is actively accelerating its digital capabilities to enhance customer experience and retail operations at scale, making technology a core driver of business growth
You’ll work in an XP / Agile setup (pairing/mobbing, continuous refactoring, frequent releases) with full lifecycle responsibility. Teams operate with full-stack ownership (no separate QA department) and a “you build it, you run it” mindset, actively avoiding knowledge silos through collaboration, rotation, and documentation
We are looking for someone with good communication skills, ideally with experience making decisions, being proactive, used to building software from scratch, and with good attention to detail.
What you will do:
- Build, evolve, and run production services and UI capabilities in a Self-Contained Systems environment with end-to-end team ownership.
- Deliver backend solutions using Java/Kotlin + Spring Boot, developing reliable microservices and robust REST APIs.
- Deliver frontend capabilities by consuming and extending Web Components / design system components, building Vue-based client-side rendered (CSR) experiences and contributing to server-side rendered (SSR) / MVC templates when required.
- Implement event-driven integrations using Kafka (Streams highly valued), alongside synchronous HTTP integrations where needed.
- Apply Domain-Driven Design (DDD) and hexagonal / ports-and-adapters architecture to model and evolve complex retail domains.
- Engineer for resilience and reliability using patterns like timeouts, retries, bulkheads, and fallbacks, and ensure services are observable in production.
- Take shared ownership of quality across the SDLC (unit, integration, and E2E testing) with no separate QA department.
- Work in an XP/Agile way (pairing/mobbing, continuous refactoring, frequent releases) and support a culture of learning and knowledge-sharing.
- Operate with a “you build it, you run it” mindset: collaborate on CI/CD, monitoring, incident response, and continuous improvement.
What you will bring:
- 8+ years of professional experience or equivalent Senior Software Engineer III depth.
- Strong backend experience with Java and Spring Boot, delivering microservices and production-grade REST APIs.
- Strong frontend capability with Web Components, TypeScript, and Vue (or similar) SPA/CSR architectures, plus experience in SSR / MVC template environments.
- Excellent CSS skills and experience working with Design Systems, including consuming and contributing shared components.
- Accessibility-first UI development mindset (semantic HTML, WCAG basics, keyboard/screen reader awareness).
- Solid SQL / PostgreSQL knowledge and comfort working with data-driven systems.
- Hands-on experience with Kafka in distributed systems (Streams a strong plus).
- Practical experience applying DDD; ability to align service and UI boundaries to domain concepts.
- Experience with or strong interest in hexagonal / ports-and-adapters architecture and resilience patterns in real systems.
- A production mindset: understanding of cloud, containerization, continuous deployment, and how frontend assets are built and served, with strong observability habits (logging, metrics, performance/UX monitoring).
- Comfortable working in XP / Agile teams with pairing/mobbing, continuous refactoring, and frequent releases.
- Mac as your primary development environment.
- Excellent communication and collaboration skills, friendly, open to feedback, and happy to teach and learn in cross-functional teams.
- Interest in the e-commerce domain and a habit of using AI tools to enhance delivery (coding assistants, analysis, test generation, UI prototyping/accessibility checks)
Nice to have:
- Kotlin in production.
- Event-driven or message-based systems beyond core Kafka usage.
- UX design background or strong UX intuition.
- Flutter app development.
- Frontend performance optimization (bundle size, Core Web Vitals, perceived speed).
- Experience with security / compliance in e-commerce contexts.
