Snr Principal Systems Engineer - Architect – Command & Control

Date Posted:

Country: United Kingdom

Location: Winnersh, Wokingham

Position Role Type: Hybrid

Collins Aerospace, an RTX business

Location: Winnersh, UK

At Collins Aerospace, we are advancing the technologies that connect, protect and enable mission success across air, land and maritime domains. Our teams work on complex systems where communications, networking, autonomy, AI and secure information flow come together to support real‑world operational capability.

Modern missions depend on fast, secure and resilient information. Whether across airborne, land or maritime environments, Command and Control systems need to connect people, platforms, sensors, networks and decision‑making tools in a way that is reliable, scalable and operationally effective.

In this role, you will help define the systems that make that possible.

You will work at the intersection of systems engineering, military communications, networking, autonomy, AI‑enabled workflows and mission systems architecture, supporting both current programmes and future technology development.

You will contribute to the identification of emerging and future technologies, with a primary focus on Command and Control, including communications, networking, AI, autonomy and information management.

You will define and develop CONEMP and CONOPS for mission systems, helping to describe how systems will be used in real operational scenarios and how they will deliver value at a systems‑of‑systems level.

You will capture, analyse and translate customer needs into clear system requirements, architectures and technical solutions, particularly in complex or evolving domains where requirements may not be fully mature at the start.

You will develop and assess architecture options, carry out technical trade studies, and produce clear recommendations that balance capability, cost, risk, complexity and delivery feasibility.

You will support bids and early‑stage programme activity by shaping technical solutions, delivery plans, estimates and work breakdown structures.

You will provide technical leadership and systems engineering guidance across the lifecycle, supporting robust delivery against time, cost and quality expectations.

You will act as a technical mentor, helping others deliver high‑quality engineering outputs and supporting the development of capability across the wider team.

You will collaborate with internal Collins teams, RTX business areas, external suppliers, Business Development, Programme Management and technical specialists to develop integrated solutions.

You will identify technical risks and mitigations, support technical governance, and ensure appropriate engineering plans are created and followed throughout the project lifecycle.

You will also support design activity involving export‑controlled technologies, including awareness of US ITAR controls where applicable.

You will be an experienced Systems Engineering practitioner with strong capability across the full engineering lifecycle, particularly in early‑stage concept development, requirements definition and architecture design.

You will be comfortable working with uncertain or evolving customer needs and turning them into structured technical direction.

You will bring strong knowledge of military communication systems, heterogeneous networks, networking concepts and security functions.

You will have experience defining and eliciting system and subsystem requirements, developing high‑level architectures and using systems engineering methods, tools and processes to guide technical delivery.

You will be confident engaging with technical and non‑technical stakeholders, including customers, suppliers, engineering teams, programme teams and business development colleagues.

You will be able to make sound engineering judgements based on requirements, constraints, risks, costs and delivery realities.
