MUST BE A U.S. CITIZEN. This role will involve up to 10% of CONUS travel.\nJRE is a combat-proven data link gateway that plays a vital role in the defense of the United States and our allies by extending the reach of tactical data across the battlespace and around the globe. It is a large, mission-critical, near-real-time system written predominantly in Java and Kotlin, and also includes C++ components. JRE is deployed everywhere from handheld devices and small-form-factor drones to strategic bombers, guided-missile destroyers, and global command-and-control centers.\nAs a Principal Software Development Engineer in Test (SDET)on the software development team, you'll work closely with other developers, as well as with testers and test engineers on the test team. Through test automation, you'll play an essential role in enabling rapid, agentically-developed, high-quality releases of JRE to meet the current and future mission needs of the warfighter.\nYour impact will extend beyond the code you write yourself. You'll lead projects and build up the test engineering skills of the people you work with.\nJOB DUTIES:\nExpand JRE's unit, integration, service, GUI, and end-to-end test automation.\nEngineer and maintain a comprehensive automated performance test suite covering load, stress, and endurance testing; support our IT team with capacity planning for the hardware environment it requires.\nDesign, develop, and maintain advanced simulators for IP and serial tactical data link terminals, radios, navigation systems, and sensors.\nContribute to the definition and ongoing verification of minimum system requirements for JRE's full range of deployment platforms.\nRefactor JRE code for testability, introducing API, RPC, and messaging seams to enable additional white- and gray-box testing.\nMentor developers, testers, and less-experienced test engineers in test automation best practices as we expand automated coverage across the codebase.\nOptimize the performance and quality of our test automation suites.\nQuarantine, troubleshoot, and fix nondeterministic tests.\n REQUIREMENTS:\nTechnical Qualifications\nDeep expertise in the JVM platform, including fluency with Java, and familiarity with JVM languages such as Kotlin or Scala.\nProven experience developing and maintaining high test automation coverage for large-scale codebases (1M+ lines).\nExperience with the verification of mission-critical, high-reliability, near-real-time systems.\nExperience with JVM testing and mocking frameworks such as JUnit, AssertJ, Mockito, and MockK.\nFamiliarity with C++ and related test automation frameworks such as Doctest and Google Mock.\nExperience with automated performance testing using tools such as JMeter or Gatling.\nSolid understanding of concurrent programming on the JVM, including classic Threads, the Executor Framework, Futures and Promises, Virtual Threads, the Reactor framework, and Kotlin Coroutines.\nExperience testing concurrent and asynchronous code, including with utilities such as Reactor Test and Kotlinx Coroutines Test.\nThorough knowledge of object-oriented and functional design patterns; software design principles; refactoring techniques, code and test smells, and domain-driven design.\nExperience with RPC and message-oriented distributed systems.\nExperience with network programming, networking protocols, and the low-level processing of binary data.\nExperience leading successful large-scale, phased refactoring projects.\nExperience mentoring developers and testers in test automation best practices.\nExperience with dependency injection and the Spring family of frameworks, including Spring Boot, Spring Data, and Spring Security, and their related integration testing utilities.\nTest-driven development experience, and team-based development experience via pairing or mobbing, with an eagerness to work collaboratively.\nExperience designing and developing solutions iteratively and incrementally via Agile methodologies such as Scrum, Extreme Programming, or Lean Software Development.\nExperience with continuous integration and modern deployment practices for edge and cloud systems, in Gradle-built projects.\nCredentials and Education\nBachelors and nine (9) years or more experience; Masters and seven (7) years or more experience ; PhD or JD and four (4) years or more experience.\nMust be a U.S. Citizen.\nMust be able to obtain a Secret Clearance after start.\nDESIRED SKILLS:\nPublic contributions to open-source projects.\nFamiliarity with any of the following:Tactical data link standards such as MIL-STD-6016, MIL-STD-6017, MIL-STD-3011, MIL-STD-6020, MIL-STD-6040, MIL-STD-2525, MIL-STD-1553, etc.\nTactical terminals and radios such as MIDS JTRS, STT, BATS-D, AN/ARC, and AN/PRC.\nNavigation and avionics standards such as NMEA 0183, GPS-153, ARINC 429, and ARINC 661.\nSecurity standards such as DISA STIGs, NIST SP 800-171, and NIST SP 800-207.","description_format":"text","description_chars":5072,"description_truncated":false,"requirements":{"experience_years_min":9,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Digital Government","Systems Integrators","Engineering Services"],"lifecycle":[{"event":"open","at":"2026-10-24T00:56:30Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.629,"p_room":1,"age_days":4,"expected_fill_days":18,"reasons":["conf:2","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-26T05:57:25Z"},"pay":null,"html_url":"https://alion.io/job/saic-principal-software-development-engineer-in-test","json_url":"https://alion.io/job/saic-principal-software-development-engineer-in-test.json","meta":{"generated_at":"2026-10-27T04:35:14Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":4105,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":58788},"rest":"https://alion.io/mcp/rest/get_company?id=58788"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsaic-principal-software-development-engineer-in-test"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fsaic-principal-software-development-engineer-in-test"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fsaic-principal-software-development-engineer-in-test"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/saic-principal-software-development-engineer-in-test\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsaic-principal-software-development-engineer-in-test"}]}
