Staff Full-Stack Engineer

Jobtailor; Cork; On-site; EUR 100,000 - 150,000; Full time

Job summary

Jobtailor is seeking a senior full-stack developer to lead end-to-end feature delivery. You will write high‑performance Java for the API layer and modern JavaScript/TypeScript for the frontend, transforming sketches into working software with velocity.

You will architect dashboards for non-technical users to interact with large datasets, design robust APIs, and focus on time-to-value and UX while avoiding over-engineering to deliver fast results.

Qualifications

• 6+ years of full-stack software development experience.
• Deep proficiency in modern component-based frontend frameworks and managing complex state in the browser.
• Strong working knowledge of Java for backend service development.
• Experience writing SQL and interacting with data platforms.
• Solid grasp of UI/UX principles for building intuitive and accessible interfaces.
• Experience with advanced data visualization techniques for rendering large datasets may be useful.
• Familiarity with Kubernetes and containerised deployments is a plus.
• Background in building internal tools, developer platforms, or B2B SaaS applications is advantageous.

Responsibilities

• End-to-End Execution: independently determine the best implementation approach for assigned features.
• Write high-performance Java code for the API layer and modern JavaScript/TypeScript for the frontend.
• Rapid Prototyping: transform whiteboard sketches and mock-ups into working software with high velocity.
• Architect custom dashboards and interfaces that allow non-technical users to interact with massive datasets.
• Design and implement robust APIs that decouple the frontend from backend systems.
• Prioritise 'Time to Value' and user experience, pushing back on over-engineering when a simpler solution delivers faster.
