Sr Software Engineer - PHP/Java

As a Sr Software Engineer - PHP/Java on the Expert Medical Opinion (EMO) platform, you will help design, build, and operate the technology that connects members with world-class medical experts when they need them most. This is a Prague-based position with a hybrid working model - we expect you in the office 2-3 days per week, collaborating with the local Prague team and our colleagues in the US. You’ll work on a platform that blends a long-running PHP codebase with a modern Domain-Driven Design layer, deployed on AWS. You’ll partner with product managers, internal stakeholders, and your manager to turn complex healthcare requirements into reliable, well-architected software - and have a direct impact on the quality of care our members receive.

What you’ll do:

• Understand business requirements and the scope of enhancements, working closely with product and stakeholders

• Design, architect, and plan the delivery of new features and ongoing maintenance with a clear systems-design mindset

• Take ownership of deliverables, hitting timelines without compromising quality

• Write and maintain solid Unit and Functional tests as a standard part of how you ship

• Perform thoughtful code reviews and provide coaching and mentorship to more junior team members

• Use AI coding tools effectively - with a strong focus on architecture, review, and rigorous validation of AI-generated solutions rather than blind acceptance

• Help evolve our existing PHP codebase - layering in DDD, strengthening boundaries, and gradually moving toward a cleaner, service-oriented architecture

What we’re looking for:

• Solid experience developing backend web applications with MySQL, alongside server-rendered HTML / CSS / JavaScript - our frontend is not a modern SPA, though we do have some components built in Vue.js; comfortable working with PHP (prior PHP experience is a plus, not a hard requirement)

• Java or Kotlin experience is preferred, but we are also open to candidates with experience in another high-level programming language who are motivated to learn Java or Kotlin. The project is undergoing a major rearchitecture and refactoring, providing an opportunity to contribute from the early stages of breaking down the existing solution into a modern microservices architecture.

• Strong discipline around automated testing - writing and maintaining Unit and Functional tests is a must, not an afterthought

• Solid grasp of layered architecture and separation of concerns (e.g. Domain-Driven Design, Clean/ Hexagonal architecture) - able to reason about boundaries, dependencies, and where logic belongs

• Experience in Cloud Architecture or a strong systems-design mindset - comfortable reasoning about scalability, reliability, and trade-offs

• Experience working on Enterprise applications - or a strong appetite to dive into a complex business domain (healthcare / medical consultations) and grow into a domain owner over time

• AI-friendly developer - comfortable working alongside AI coding tools, with a focus on architecture and rigorous validation of AI-generated solutions

• Working experience building REST APIs and using Git in a collaborative team setting

• Solid foundation in modern DevOps culture and comfort with Docker-based development workflows

• Skillful communicator who thrives in a collaborative, agile environment and works well with technical and product stakeholders

Nice to have:

• Prior experience with PHP and frameworks such as CodeIgniter or Symfony

• Hands-on experience with AWS services such as IAM, S3, RDS, ECS, and API Gateway

• Experience working in healthcare, regulated industries, or other domains with strong privacy/security requirements

• Experience modernizing or migrating legacy codebases toward microservices or service-oriented architectures

• Familiarity with static analysis tools (e.g. PHPStan, Psalm), architectural fitness tooling (e.g. Deptrac), or similar quality-enforcing tooling.
