Quality Assurance & System Test Engineer in ATS Environment

Project overview

Quality Assurance & System Test Engineer in ATS Environment

Contract Type: Permanent position, Partner or Freelance / Project contract

We are looking for a competent partner with whom we can jointly create an offer for comprehensive team staffing.

Contract Period: from mid-2027 onwards (multi-year contract)

The subject of this specialized role is the formal quality assurance, acceptance, verification, and evidence management of safety-critical air traffic control software. The focus is on heterogeneous real-time systems – including radar data and flight plan data processing (Surveillance / Flight Data Processing), collision warning systems, as well as controller and tower systems at the 16 German tower locations.

Responsibilities

• Test Specification & Design: Analysis of functional and non-functional requirements from requirements management systems (IBM Rational DOORS, OpenText Dimensions RM) for uniqueness, consistency, and testability; derivation of formal test concepts and scenarios.
• Test Execution across all Test Levels: Specification, preparation, and execution of unit, integration, system, acceptance, and regression tests in heterogeneous ATS system structures (radar, flight plan, warning, and tower scenarios).
• Test Environments & Test Data: Setup, provision, and maintenance of valid test data sets as well as operation of test environments under Linux.
• Defect Management: Precise recording, prioritization, classification, and tracking of errors/deviations in MANTIS and IBM Rational Change until successful re-verification.
• Safety Cases & Compliance: Seamless proof of requirements traceability, support for EASA compliance demonstration, and creation of meaningful test reports for evidence management for safety cases according to ED-153.
• Security Testing: Consideration and verification of IT security requirements according to BSI-Grundschutz and OWASP-ASVS in the test cases.

• Test Management & Test Levels: Sound practical experience in the conception and execution of all test levels (unit, integration, system, acceptance, regression) for heterogeneous backend and real-time systems.
• Requirements & Test Traceability: Confident handling of IBM Rational DOORS and/or OpenText Dimensions RM for requirements analysis and complete test coverage.
• Defect Tracking: Demonstrable experience with MANTIS and/or IBM Rational Change.
• Operating System & Test Environment: Routine handling of Linux environments for test execution and test data maintenance.
• Standards & Air Safety Standards: Sound methodological knowledge regarding ANS Software Life Cycle according to ISO/IEC/IEEE 12207 and air safety regulations according to EUROCAE ED-153 (Software Safety Assurance) as well as DIN EN ISO 9001 (DFS V-Model).
• Security Testing: Understanding of security aspects according to BSI IT-Grundschutz and OWASP-ASVS.
• Prerequisites:
• Valid security clearance (ZÜP) according to § 7 LuftSiG (or demonstrable prerequisites for immediate issuance).
• Language Skills: Very good German and English, spoken and written.
• Certification according to ISTQB (e.g., Certified Tester Foundation Level / Advanced Level Test Analyst or Technical Test Analyst).
• Domain knowledge in the area of ATS/ATM (Surveillance, Radar Data Processing, Flight Data Processing, Asterix protocols, electronic flight strips).
• Profile submission for pre-selection: by 13.11.2026 at 10:00 AM at the latest
