Senior Software Engineer (Java)

🏢 Summary: Join a strategic engineering initiative to standardize behavioural-event tracking and data quality across a large product ecosystem. The role involves investigating event sources, implementing Java/Kotlin backend and API changes, integrating Segment, and making occasional React frontend updates through the end of the year. 🗂️ Requirements: 5+ years of commercial Java and Kotlin experience, Experience maintaining existing systems across multiple repositories or codebases, Ability to investigate issue origins, system ownership and dependencies, Strong cross-team communication with engineers and stakeholders, Pragmatic approach to legacy systems and organisational complexity, Basic React knowledge for web frontend adaptations, Practical use of AI tools for engineering discovery, implementation or validation 📃 Skills: Java, Kotlin, React, APIs, AI 🏢 Description: Join a new engineering team and help standardize how one of Austria’s largest digital platforms captures and activates user-behaviour data. You’ll support a strategic data-driven initiative focused on standardizing tracking events, improving data quality and enabling marketing and other business teams to make better use of behavioural data. This is not about delivering tickets within a single backend service. You’ll navigate an extensive product ecosystem, identify where events originate, collaborate with system owners and implement changes across backend, web and data-platform integrations. Tech stack: Java, Kotlin, React, APIs, Segment, event tracking and customer data platforms. The assignment is planned to run until the end of this year. Your everyday playground: Improve and standardize tracking events across product ecosystem. Investigate where particular events are generated and identify the relevant projects, repositories and system owners. Design and implement backend and API changes using Java and Kotlin. Integrate behavioural data with Segment and the wider data ecosystem. Make necessary adjustments in the React-based web application when required. Raise technical risks, clarify dependencies and involve other developers when a change requires broader coordination. Move between different repositories and systems while taking ownership of each topic from discovery to delivery. What are we looking for? 🕵️‍♀️ Strong commercial experience with Java and Kotlin (min. 5 years of experience) Experience working with existing systems and navigating multiple repositories or codebases. A proactive discovery mindset: you know how to identify where a problem originates, who owns the relevant system and what context is needed before making a change. Strong communication skills and confidence in approaching engineers and stakeholders from other teams. A pragmatic approach to legacy systems and organisational complexity. Basic React knowledge that allows you to make necessary adaptations in a web frontend application. Practical use of AI tools to accelerate engineering discovery, implementation or validation. Bonus points: Experience with Segment or a comparable Customer Data Platform. Experience with event tracking, product analytics or marketing analytics. Knowledge of event-taxonomy or event-schema design. Experience integrating backend, web and mobile applications with data or analytics platforms. Understanding of data quality, tracking consistency and behavioural-data flows. Experience supporting initiatives that span several engineering teams or product areas. Why join us? 🌟 A meaningful initiative: you’ll contribute to a strategic programme that supports data-driven marketing and future business use cases. Real engineering ownership: the desired outcome is defined, but you’ll have autonomy in deciding how to implement it safely and effectively. Work beyond a single repository: you’ll investigate systems, map dependencies and collaborate with the people who understand each product area best. Sounds like a fit? Let’s talk! 🚀

🏢 Summary: B2B full-stack product engineering cooperation with a strong frontend focus, delivering user-facing hospitality software features from discovery and design through production release. The role combines VueJS-based frontend craft, daily PHP/Laravel backend work, product judgment, UX quality, and AI-augmented development in a remote-first model. 🗂️ Requirements: Strong commercial experience with TypeScript, JavaScript, VueJS, Tailwind, and Pinia, Experience with component architecture, state management, and performance, Documented backend engineering experience with PHP and Laravel, Knowledge of design patterns, APIs, caching, database query optimization, microservices, and message queues, Ability to deliver frontend and backend features end-to-end, Communicative Polish and English 📃 Skills: TypeScript, JavaScript, VueJS, Tailwind, Pinia, PHP, Laravel, Node.js, REST, Docker, GitLab, MySQL, MariaDB, MongoDB, Redis, Microservices, Kubernetes, Claude, Cursor 🏢 Description: The ability to build software is no longer rare. AI has made execution accessible to almost everyone. What's rare now is judgment — understanding customer problems, making sound decisions, and knowing where to create real value. The role At Profitroom we build hospitality software used by thousands of hotels and millions of guests. In this cooperation, you take responsibility for technical initiatives end-to-end: from technical discovery and solution design, through implementation and testing, to release and production readiness. The Product Manager steers direction and owns the what and why. You own the how and the technical solution. This is a full-stack product engineering cooperation with a strong frontend focus . Your technical home is the frontend: user journeys, component architecture, interaction design, and UX quality. You also work across the backend when AI, established patterns, and your experience make it practical — for example, when connecting APIs, implementing business logic, or building integrations. Frontend development and product engineering are not the same thing. Frontend without product judgment is implementation. Product judgment without frontend craft is wireframes. We're looking for both — plus the full-stack reach to deliver a feature end-to-end without handing half of it off. “The builder drives; the PM steers.” This is what we mean by product engineering. Not just a label — a way of working. What you'll actually do Full-stack delivery of user-facing features — the frontend and the backend behind it, designed, built, tested, and shipped by you Technical discovery — together with the PM, you validate feasibility, identify constraints, and shape the technical approach before scope is locked End-to-end quality — you care whether the experience works in production, not only whether it passed review AI-augmented development — Claude Code is our daily driver; MCP servers, custom agents, and internal tooling are part of the real workflow Close collaboration with Product Managers and backend engineers — you own the how; the PM owns the what and why UX coherence — you notice recurring issues, raise them, and leave the product better than you found it → Tech stack Full-stack, TypeScript, JavaScript,VueJS , Node.js, Claude Code, MCP servers, AI agents, REST API, Docker, GitLab CI/CD, PHP, Laravel, MySQL / MariaDB, MongoDB, Redis, Microservices, Kubernetes. What we're looking for: Technical expectations: TypeScript & JavaScript, VueJS, Tailwind and Pinia — strong commercial experience; component architecture, state management, performance; you've built real things with these technologies. UX sensibility — you notice what's wrong before users complain; interaction quality matters to you. PHP & Laravel — you have documented experience with backend engineering, you understand concepts like design patterns, APIs, caching, database query optimization, microservices, message queues. It’s a full-stack job, writing backend will not be an occasional favour but your daily task. AI tooling — hands-on Claude Code, Cursor, or equivalent; experience generating backend integrations with AI and understanding advanced topics like skills, spec-driven developmen, feedback loops; is a strong plus. Communicative Polish and English — you work closely with PMs, QA, and software engineers. You'll enjoy collaborating with us if: You've shipped user-facing features that real people used — and you know what broke and why You notice UI details that most engineers scroll past, and it bothers you when they're wrong You get curious about the business reason behind a feature before you start building it Taking responsibility for a feature end-to-end — from the PM conversation through to production — feels like the natural way to work AI tools feel like a natural extension of how you work; you use them to move beyond the frontend boundary into full-stack work when needed You care about what happens on a slow connection, with a keyboard, and on a screen size nobody designed for You can weigh in on whether a feature is worth building without needing to be the person who makes the final product decision Bonus points: You have a side project — something you built, shipped, and perhaps use yourself You use AI tools on your own account, not only when they are provided as part of a project You've worked with or contributed to a design system or component library You've built Node.js services or backend integrations beyond the occasional CRUD endpoint Probably not for you if: Your definition of “done” is a Figma-accurate implementation, regardless of how it actually works for users Backend is someone else's problem and that's a firm boundary for you Your hands-on AI experience is mostly autocomplete and the occasional PR summary Contract terms: B2B cooperation. Monthly compensation range: 15,000–25,000 PLN net , depending on experience and the agreed scope of services. Remote-first collaboration model International technology and product projects Flexible project collaboration setup Planned service breaks aligned with contract terms Opportunity to collaborate with experienced product and technology teams Opportunity to access selected knowledge-sharing initiatives → Recruitment process Intro call with the Recruiter (up to 45 minutes). We cover your background, what you're looking for, and mutual fit. Technical interview with the Team Leader, Tech Lead, and Product Manager (up to 90 minutes). Expect concrete technical questions and a discussion of how you approach frontend architecture, full-stack delivery, product ownership, and the practical use of AI. We care about judgment and initiative, not keyword recall. Technical task. A time-boxed, practical challenge reflecting the type of services involved in the cooperation, reviewed together in a follow-up call. We care about your process, UX decisions, and how you handle the parts that go beyond the frontend.
