Senior / Lead Fullstack Java Engineer (m/f/d)

The Role:

We’re partnering with a highly regarded IT consultancy delivering complex transformation and engineering projects across enterprise clients, with a strong focus on the financial services sector. They’re looking for a Senior / Lead Fullstack Java Engineer to take ownership of modern, business-critical systems while acting as a senior technical voice across projects. This role combines hands-on engineering, architecture influence, client interaction, and technical leadership — ideal for someone who enjoys solving complex challenges while mentoring others and driving engineering quality. You’ll work closely with stakeholders, consultants, and development teams to deliver scalable, production-grade solutions across the full project lifecycle.

What You’ll Be Doing:

• Lead the development of modern fullstack applications using Java (Spring Boot) and modern frontend technologies
• Drive technical architecture and design decisions across client projects
• Act as a senior technical contact for clients and internal stakeholders
• Build scalable, production-ready systems within enterprise environments
• Mentor and support developers within agile project teams
• Translate complex business requirements into clean, maintainable technical solutions
• Contribute to engineering best practices, code quality, and development processes

What We’re Looking For:

• Strong commercial experience with Java / Spring Boot
• Fullstack expertise with technologies such as Angular, React, or similar frontend frameworks
• Experience leading technical initiatives or acting as a senior engineer within project environments
• Background in consulting, enterprise delivery, or client-facing engineering roles
• Experience within finance, banking, or fintech environments is highly beneficial
• Strong understanding of software architecture, agile methodologies, and modern engineering practices
• German C1+ (mandatory) and strong English skills
• Based in or open to working within the Frankfurt region

Why This Role Stands Out:

• Work on high-impact enterprise systems within financial services
• Opportunity to operate as a technical leader while remaining hands-on
• Join a consultancy recognised for strong engineering expertise and long-term client partnerships
• Hybrid working model with only 2 days onsite
• Clear progression toward Lead / Principal / Architect-level responsibilities
• Collaborative, mature engineering culture with real ownership and autonomy
