We are looking for a highly experienced Lead Java Developer (Java + Angular) who will act as a senior technical pillar for IoT R&D platform operations. This role is hands-on and production-focused, combining advanced Angular frontend development with robust backend services in Java, as well as operational excellence in a cloud-based IoT environment.
The senior engineer is also expected to guide and mentor middle/junior developers as the team scales.
Key Responsibilities
Frontend Angular
- Design, enhance, and maintain enterprise-grade Angular applications used globally.
- Work extensively with RxJS and state management (NgRx Store / Component Store) for complex, data-driven UIs.
- Build scalable UI modules such as:
o Authentication & authorization
o Reporting dashboards
o Dynamic forms
o Role-based access and impersonation flows
- Apply Angular best practices:
o OnPush change detection
o Efficient observable patterns
o Modular and maintainable architecture
- Collaborate closely with backend and cloud services to ensure reliable data flow and performance.
Backend (Java)
- Develop and maintain backend services in Java (e.g. Spring Bootbased REST APIs), functionally equivalent to the Python/FastAPI services described by the customer.
- Implement secure APIs with:
o Authentication & authorization
o Clean API contracts for frontend and IoT consumers
- Support backend logic for:
o Data ingestion and processing
o Configuration management
o Integration with cloud and IoT services
- Contribute to debugging, log analysis, and production issue resolution.
Cloud, IoT & Operations

o Monitoring and log analysis
o Incident handling and root-cause analysis
- Improve monitoring and alerting (e.g. CloudWatch; similar tools acceptable).
- Handle operational tasks:
o Incident tickets
o Jira bug tracking
o Release notes and technical documentation
Technical Leadership
- Act as a senior technical reference within the team.
- Mentor and supervise junior developers as additional resources are onboarded.
- Promote clean code, documentation, and reliable engineering practices in a production environment.
Required Skills & Experience
Experience
- Senior Level: Minimum 8 years of hands-on software development experience.
- Middle Level: Minimum 4 years of hands-on software development experience.
- Proven experience working on long-running, production systems with high reliability requirements.
Technical Skills
Frontend (Must-have)
- Angular development experience.
- Deep understanding of RxJS, Observables, and NgRx.
- Strong TypeScript, HTML, CSS skills.
Backend (Must-have)
- Strong Java backend development experience (e.g. Spring Boot, Spring EcoSystem).
- REST API design and integration.
- Authentication and authorization concepts.
Cloud & Platform
- Very good experience with AWS (e.g. Lambda, DynamoDB, CloudWatch, IoT-related services).
- Version control with Git.
- Issue tracking and documentation using Jira and related tools.
Nice to Have
- Experience with IoT platforms.
- Experience with FastAPI or Python-based services (conceptual equivalence).
- Automated testing experience.
Personal Attributes
- Reliable and meticulous working style suitable for productive, globally used systems.
- Strong communication skills in English.
- Comfortable working in an operations-heavy environment, not only greenfield development.
- Able to balance hands-on coding with mentoring responsibilities.
