What does a systems integration test engineer do?

A Systems Integration Test Engineer is responsible for ensuring that different components of a system work together as intended. They design, plan, and execute tests that validate the integration of hardware, software, and network elements in complex systems. Their work helps identify and resolve compatibility or functionality issues before deployment. This role often involves collaborating with development, quality assurance, and engineering teams to ensure system reliability and performance.

What are the key skills and qualifications needed to thrive as a systems integration test engineer?

To thrive as a Systems Integration Test Engineer, you need a solid background in systems engineering, software/hardware integration, and testing methodologies, often supported by a relevant engineering degree. Familiarity with test automation tools, scripting languages (such as Python or Bash), and requirements management systems is typically required. Strong analytical thinking, problem-solving ability, and clear communication skills help you collaborate effectively and troubleshoot complex integration issues. These skills ensure seamless system performance, timely defect identification, and successful deployment of integrated solutions.

What are common challenges faced by systems integration test engineers during large-scale project deployments?

Systems Integration Test Engineers often encounter challenges such as coordinating between multiple teams, managing complex dependencies, and ensuring compatibility among various hardware and software components. Large-scale deployments require robust test planning and adaptability, as unforeseen issues can arise when integrating different systems. Effective communication and problem-solving skills are crucial to address integration bugs quickly and to keep the project timeline on track. Collaborating closely with development, QA, and operations teams helps ensure a smooth integration and successful deployment.

What is the difference between Systems Integration Test Engineer vs Software Test Engineer?

AspectSystems Integration Test EngineerSoftware Test Engineer
CredentialsBachelor's in Engineering or Computer Science, certifications like ISTQBBachelor's in Computer Science or related field, ISTQB certification common
Work EnvironmentHardware and software integration labs, manufacturing environmentsSoftware development teams, testing labs, virtual environments
Industry UsageElectronics, aerospace, automotive, telecommunicationsIT, software development, app development
Common Search IntentUnderstanding roles in system integration and testingTesting software applications and features

The main difference is that Systems Integration Test Engineers focus on verifying the integration of hardware and software systems, ensuring components work together seamlessly. Software Test Engineers primarily test software applications for bugs and performance. Both roles require similar certifications and often work in overlapping industries, but their focus areas and environments differ.

Are systems integration test engineers in demand?

Systems integration test engineers are in high demand across industries such as aerospace, defense, and technology, as companies require thorough testing of complex systems.

Job description

Astranis builds advanced satellites for high orbits, expanding humanity's reach into the solar system. Today, Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe- large enterprises, sovereign governments, and the US military. With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts.
Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization. Astranis has raised over $750 million from some of the world's best investors, from Andreessen Horowitz to Blackrock and Fidelity, and employs a team of 450 engineers and entrepreneurs.

Hardware Integration Test Engineer
We are seeking a highly skilled and motivated Hardware Integration Test Engineer to join our rapidly-growing team. In this role, you will be responsible for designing, building, and maintaining the hardware-in-the-loop (HITL) testbeds that serve as the primary proving ground for every satellite we build and fly. You will collaborate with nearly every engineering team - Flight Software, Guidance Navigation & Control, Avionics, Power, Payload, and Mission Ops - to ensure our testbeds are flight-representative, reliable, and always ready to support testing. If it runs on a satellite, it gets proven on HITL first.
Role
  • Own the full lifecycle of flatsat and HITL testbed builds, from initial design and BOM development through hardware procurement and software bring-up
  • Scope and design harnessing needs, coordinating with manufacturing to produce custom harnesses for flight-like hardware
  • Serve on a rotating on-call point of contact for testbed health, triaging anomalies and managing access for other engineers
  • Diagnose and resolve hardware and software failures on the testbed, spanning firmware interfaces, flight software, and physical components
  • Drive testbed architecture decisions, including hardware allocation tradeoffs and risk mitigation for testbed contention
  • Expand simulation capabilities as new satellite blocks come online, integrating motor emulators and deployment simulators
  • Develop tooling to improve testbed observability, monitoring, and automated operations
  • Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team

Requirements
  • Bachelors degree in EE, AE, CS (or equivalent background knowledge)
  • 2-5+ years of experience in hardware integration, systems bring-up, or test engineering
  • Comfort working across hardware and software, from rack assembly to debugging Python tracebacks
  • Experience with embedded systems, proprietary test hardware, or laboratory hardware like logic analyzers and oscilloscopes
  • 2+ years of experience with Python (or equivalent high-level scripting language) for test automation
  • 1+ years of experience with Linux and shell command line tools
  • 1+ years of experience with version control systems (git or equivalent)
  • Experience reading schematics and debugging circuits that interface with embedded software
  • Strong debugging instincts and a methodical approach to documenting novel failures
  • Excellent written and verbal communication skills
  • A passion for building things, including working in a fast-paced environment and hands-on development

Bonus
  • Familiarity with flight software architectures, telemetry systems, or simulation frameworks
  • Prior experience with networked lab infrastructure, Kubernetes, or Linux system administration
  • Please apply even if you do not meet every single criterion listed above
