First seen by Alion on Oct 30, 2026.
Job Description :
1. Enterprise Java Application Development :
- Develop and extend enterprise Java services and related integrations.
- Required capabilities include Java, REST APIs, Oracle SQL/PLSQL, background jobs, service concurrency, and maintenance of existing production applications.
2. Large-File and Distributed Workflow Engineering :
- Design and implement reliable handling up to 50GB files using streaming I/O, asynchronous processing, chunking, packaging, bounded concurrency, resumable transfer, retry, timeout, cleanup, and recovery.
- Engineers must safely handle large offsets and avoid loading complete payloads into memory.
3. API, Signing, Validation, and Data Integration :
- Integrate Java services with existing authentication, signing, validation, storage, and upstream or downstream interfaces.
- The work requires understanding checksums versus digital signatures, metadata and manifest contracts, binary compatibility, file-validity checks, and interface error handling.
4. Automated Testing, Performance, and Troubleshooting :
- Create unit and integration tests for normal, boundary, performance, and failure conditions.
- Engineers must diagnose CPU, memory, disk, network, concurrency, partial-transfer, corruption, duplicate-chunk, and recovery problems and provide repeatable evidence for system and integration reviews.
5. Controlled Aerospace Delivery and Traceability :
- Deliver reviewed changes through controlled repositories, build pipelines, cybersecurity checks, configuration management, and release processes.
- Engineers must maintain requirements-to-test traceability, controlled documentation, test evidence, review records, and support qualification, acceptance, and release activities.
