**\#JoinLuby** ---------------- **Here, you’ll have the opportunity to:** * **Grow in a high-performance environment:** A culture where development is continuous, with autonomy and involvement in national and international projects that truly challenge your skills and accelerate your potential. * **Join a team passionate about technology:** Here, you’ll work alongside experienced professionals in a collaborative and disruptive environment, using the most advanced technologies available in the market. * **Make your mark on the world:** Our digital solutions directly impact the lives of thousands of people — and this is your chance to actively contribute to building a more digital and connected future. * **Work remotely and flexibly:** No matter where you are, we’re ready to welcome you onto our team! **Your Mission:** We’re seeking a Senior Full Stack Developer with strong expertise in Java to join our engineering team and lead the technical understanding of established electronic health record (EHR) systems serving thousands of clinicians. This is not a maintenance role: your focus will be to systematically map how these systems operate — including internal architecture, clinical and billing business rules, and behavior at integration boundaries — using AI-assisted development tools from day one. **Key Responsibilities:** * Lead AI-assisted technical discovery across all three systems, reading, mapping, and documenting each system’s structure, business rules, and behavior at its integration boundaries. * Map each system’s usage of the specific API, identifying how calls are made, which data is exposed, and where the integration surface is stable or fragile — delivering this mapping as a central project artifact. * Synthesize findings from the three systems to inform PS Suite integration decisions, distinguishing reusable patterns from behaviors requiring custom integration paths. * Design and implement the integration layer, developing the facade that makes it accessible to agents and compatible with the surface layer. * Define behavioral contracts via Knowledge Graph entries encoding clinical and billing rules, behavioral test suites reflecting real system behavior, and acceptance criteria guiding future integrations. * Collaborate with product teams as a knowledge source, seeking clarifications from original system developers when AI-assisted discovery reaches its limits, and documenting those responses in machine-readable, structured format. * Work with international clients. **Essential Requirements:** * Bachelor’s degree in Computer Science, Software Engineering, or related field. * At least 6 years of full-stack development experience. * Strong proficiency in Java as the primary stack. * Fluency with AI-assisted development tools (e.g., Cursor, Claude Code, GitHub Copilot, or equivalents), applying them to accelerate system understanding — not merely code generation. * Full-stack experience, including mastery of React or equivalent frontend technology, REST and FHIR API design, and fluency with relational databases. * Interest in clinical workflows, billing logic, and medical practice management systems — with a focus on identifying and codifying undocumented behaviors and regional billing variations. * Ability to distinguish essential complexity from incidental complexity, recognizing which behaviors are fundamental to clinical workflows and which are implementation artifacts. * Collaborative mindset, with sound judgment on when to deepen investigation using AI tools versus when to consult domain experts — always capturing and documenting knowledge for team reuse. **What We Offer:** * **Remote Work:** Enjoy the flexibility to work from anywhere in Brazil, with full autonomy and self-organization. * **Health & Well-being:** Health and dental insurance, life insurance, and Wellhub (Gympass). * **\+Education:** Discounts on FIAP courses and USP Esalq MBA programs to support your continued learning and growth. * **Exclusive Perks:** Discounts at Multilaser stores, referral bonuses for professionals and business opportunities, flexible working hours, and annual bonus. ### ***Learn more about our culture, benefits, and what it’s like to be a \#Luber on our*** ***Careers Page!***
