Systems Analyst (Space Domain) for Cybersecurity

📍 Tallinn / Tartu, Estonia

We are looking for a Systems Analyst to support the development of a first-of-its-kind spacecraft cyber security module (onboard traffic firewall), from proven algorithms to a qualified flight product on commercial space hardware and RTOS.

This position is responsible for the formal analytical layer between product requirements and implementation. The role covers requirements definition and baseline management, continuous traceability (requirements → design → code → test), and the preparation of the qualification evidence package.

Your main responsibilities will include

• Owning the requirements baseline - extracting, reconciling, and maintaining requirements from our development contract and its ECSS tailoring

• Maintaining requirements traceability as a continuous practice

• Constructing and maintaining the qualification and certification target

• Owning the compliance register - export control (dual-use regimes, ITAR where relevant), data protection, and customer-specific obligations - translated into engineering requirements and tracked

• Space-domain operational analysis - reasoning about product behaviour across mission phases (launch and early operations, commissioning, nominal, contingency, safe mode, decommissioning)

• Extracting the qualification evidence we need from vendors

• Supporting the Product Owner in agency and customer interactions, i.e. questionnaires, requirement capture, and keeping customer-specific commitments tracked and honoured

As a successful candidate, you must have

• Demonstrated experience in engineering or systems analysis in a regulated or certified domain, i.e. aerospace, defence, medical devices, or industrial control; the discipline transfers

• The ability to write requirements that are precise and testable

• Enough technical literacy to write requirements engineers can implement and testers can verify

• Detailed eye to notice requirements that nobody has flagged

• Experience with the intersection of engineering and external verification - certification bodies, auditors, agencies, or funders

• Communication skills that work with both engineers and non-technical external stakeholders

You will stand out by having any of the following:

• Working knowledge of ECSS and CCSDS - the structure and intent of the standards

• Direct experience with space systems in an agency, manufacturer, operator, or research context

• Having supported a formal certification or qualification process end-to-end: evidence packages, assessor interactions, findings resolution

• Background in security evaluation frameworks - Common Criteria, IEC 62443, NIST SP 800-82 - or in demonstrating detection capability to a defined standard

• Experience with requirements management tooling (DOORS, Jama, or disciplined lightweight equivalents - the rigour matters more than the tool)
