Job Description

Become a Part of ACCURIDS

Join us and help shape the future of pharmaceutical data!

At ACCURIDS, we’re building the data backbone behind life-science innovation — a system that identifies, links, and standardizes critical enterprise data in compliance with global standards such as ISO IDMP. We help global life-science companies launch products faster, more safely, and with better patient outcomes.

At ACCURIDS, you’ll join a collaborative, growth-driven environment where your work makes a real impact from day one.

As a key member of our Product Development team, you will operate with a high degree of autonomy while collaborating closely with backend and frontend engineers, QA, DevOps, and product owners. In this role, you will directly align with cross-functional engineering stakeholders and indirectly impact our customers through the features and fixes you deliver, while having direct access to our CTO as a trusted mentor and technical sparring partner

How you’ll make an impact:

• End-to-End Feature Development: Deliver product features across the full stack, seamlessly moving between our React/TypeScript frontend and modern Java/Spring Boot backend, including the GraphQL and REST API layers in between. You take independent ownership of codebase areas from refinement to production.
• AI-Driven Velocity & Innovation: Work by default in an AI-augmented way, using modern AI coding agents and tools like Cursor and Claude Code to increase output and deliver features faster. You will push the limits of agentic workflows, mastering next-generation developer tools to keep our AI-native engineering team at the forefront of software innovation.
• Backend Engineering: Implement robust services utilizing Spring Boot, manage JPA/Hibernate against PostgreSQL with Flyway migrations, optimize Elasticsearch queries, and dive into semantic data structures using the Apache Jena RDF triplestore.
• Frontend Engineering: Build responsive React components and manage global state with Redux, fetching data with Apollo Client and implementing advanced data visualizations like D3 or Recharts optimized for large datasets.
• Quality Assurance & Testing: Uphold rigorous testing standards using JUnit, Mockito, Testcontainers, and WireMock on the backend, alongside Jest, Testing Library, Cypress, and Playwright on the frontend to maintain our SonarQube quality gate.
• Architecture & Modularization: Help carve complex features into clean modules, reduce technical debt, and actively contribute to our ongoing evolution toward a multi-module Spring Modulith architecture.
• Code Review & Mentoring: Serve as an autonomous technical reference point within the team by reviewing merge requests, sharing domain knowledge, and mentoring less experienced engineers.

What helps you succeed:

• Experience: 5+ years of professional software development experience shipping and owning features end-to-end within a production SaaS product.
• AI Tooling Curiosity: Extreme comfort and enthusiasm for experimenting with next-generation agentic workflows, using tools like Cursor and Claude Code to accelerate scaffolding, refactoring, and debugging. You view AI as an opportunity, not a threat.
• Backend Mastery: Deep proficiency in modern Java (17+) and the Spring Boot ecosystem (Spring Security, Spring Data JPA), alongside relational databases (PostgreSQL) and REST/GraphQL API design.
• Frontend Expertise: Strong frontend engineering skills utilizing React 18, TypeScript, Redux state management, and Apollo Client.
• Testing & Tools: Complete fluency in testing across the full stack and managing Git-based workflows within a GitLab CI/CD environment.
• Core Competencies: Business fluency in English, an exceptional solution-oriented mindset, and a genuine curiosity to adapt quickly to new domain-heavy tools and architectures.
• Nice-to-haves: It’s a major plus if you have experience with semantic web technologies (RDF, SPARQL, Apache Jena), Material UI (MUI 5), Elasticsearch, or a basic awareness of cloud/Kubernetes operations. Prior exposure to the life sciences or pharmaceutical domains (like FHIR or IDMP) is a bonus.

Why you’ll love working here:

• Hybrid work model: Work from our Cologne office with flexible hybrid arrangements.
• 30 days of paid vacation for a healthy work-life balance.
• Competitive salary package: A fixed salary package of €75,000 – €100,000 per year, aligned with your level experience and impact in this permanent, full-time role.
• Personal growth and development: Access a flexible budget for training, conferences, or other learning opportunities that support your individual development goals.
• Choose your perk: Enjoy either a subsidized Urban Sports Club membership or a City Plus Card with a €50 monthly allowance.
• Empowerment and ownership: Take responsibility and shape your role as we grow together.
• Modern work setup: Select your preferred system and hardware – Windows, Linux, or Mac.
• Collaborative culture: Be part of a dynamic, start-up-like environment that values flexibility, trust, and innovation.

Not ticking every box?

Not ticking every box? We encourage you to apply anyway! We know great talent doesn’t always follow a checklist and we care more about your potential, curiosity, and motivation to learn.

At ACCURIDS, we’re committed to building a diverse and inclusive team. We especially encourage women and people from underrepresented backgrounds in tech, science, and data to apply.

Expert Career Tips for Senior Full Stack Developer | Java / React (f/m/d) Roles

To succeed in a competitive market as a Senior Full Stack Developer | Java / React (f/m/d), you need more than just technical skills. Here are some expert strategies to elevate your profile:

• Build a Strong Portfolio: For technical roles, a clean GitHub or a personal project site is essential. For non-technical roles, a case study portfolio demonstrating problem-solving and impact is equally valuable. Show, don't just tell, what you have achieved in your previous positions.
• Master the Narrative: When interviewing, use the STAR method (Situation, Task, Action, Result) to structure your answers. Quantify your results wherever possible—mentioning "increased efficiency by 20%" is much more impactful than saying "improved efficiency."
• Continuous Learning: The industry moves fast. Whether it's staying updated with the latest AI tools or mastering a new management methodology, continuous professional development is key. Consider obtaining industry-recognized certifications that align with Senior Full Stack Developer | Java / React (f/m/d) requirements.
• Networking: Connect with other professionals in similar roles. Join online communities, attend webinars, and engage in meaningful discussions on professional social networks. Often, the best opportunities come through referrals and community engagement.

Comprehensive Application Strategy & Hiring Process

Applying for a new role is a marathon, not a sprint. Follow this strategic approach to maximize your success rate:

1. Initial Research & Tailoring

Don't send the same resume to every employer. Spend at least 30 minutes researching the company. Look for recent news, their product roadmap, and their team structure. Modify your summary and core competencies to reflect the specific keywords found in the job description.

2. The Perfect Cover Letter

If the application allows for a cover letter, use it to tell a story that your resume cannot. Explain why you are passionate about this specific company and how your unique background makes you the perfect fit for the challenges they are currently facing.

3. Navigating the Multi-Stage Interview

Most modern hiring processes involve 3-5 stages. This typically includes a recruiter screen, a technical or skill-based assessment, a peer interview, and a final leadership round. Prepare for each stage differently: focus on enthusiasm and fit for the recruiter, technical depth for the assessment, and strategic vision for the leadership round.

4. Post-Interview Follow-Up

Always send a personalized thank-you note within 24 hours of each interview. Reference a specific topic discussed during the call to demonstrate your active listening and genuine interest in the role.

By following these steps, you demonstrate a high level of professionalism and attention to detail that sets you apart from the average applicant.

Global Market Intelligence & Relocation Insights

At JobSetuu, we specialize in helping talent navigate the global job market. Here is what you need to know about the current landscape in Cologne and beyond:

The demand for skilled professionals is increasingly borderless. For roles based in Cologne, understanding the local cost of living, visa requirements (if applicable), and cultural nuances is vital. If this is a remote role, consider the time zone alignment and the asynchronous communication culture of the hiring organization.

When evaluating an offer, look beyond the base salary—consider the total compensation package, including equity, bonuses, and healthcare benefits.

Work-Life Balance Trends: Hybrid and remote work have become standard in many regions. Research the local labor laws and common practices regarding work hours and vacation time to ensure the role aligns with your lifestyle goals.

Leveraging JobSetuu's tools can help you compare salaries across different cities and understand the "purchasing power" of your potential offer, ensuring you make an informed decision for your long-term career path.

Skills & Competency Roadmap for Professional Development

• Leadership & Strategy: Even in individual contributor roles, the ability to think strategically and lead projects from inception to completion is highly valued. Focus on stakeholder management and high-level project planning.
• Data Literacy: The ability to interpret data and use it to drive decisions is essential across all business functions. Familiarize yourself with data visualization and basic analytical concepts.
