About this opportunity and L3Harris UK

Operating at 11 sites in the United Kingdom L3Harris supports Britains mission to secure and strengthen the country by delivering sovereign innovation across the space air land sea and cyber domains.

L3Harris in Farnborough specialises in secure ground and airborne communication and network systems for the military international forces and commercial customers. We engineer and maintain night vision goggles radar systems and tactical radios. The L3Harris Falcon family of radios delivers network-centric communications for superior command and control real-time voice data full-motion HD video and crossbanding for mission-critical communications in a single integrated platform. Notably we are the proud designer supplier and maintainer of the 50000 tactical radios in the Bowman tactical C4I system in service with the UK Armed Forces and are working to define and deliver the next generation system Morpheus.

This opportunity is ideally suited to an experienced embedded software engineer with a strong foundation in digital signal processing and radio communications capable of contributing across the full lifecycle of tactical communications systemsfrom early-stage research and waveform design through to deployment sustainment and capability enhancement of in-service products.

The successful candidate will demonstrate deep knowledge of real-time embedded software development in communications systems including experience with DSP algorithms waveform implementation and Software Defined Radio (SDR) architectures. They will also possess a solid understanding of modern software engineering practices and be comfortable working at the intersection of software hardware and RF domains.

Working within a small highly collaborative engineering team the individual will engage with software systems and hardware engineers to develop robust high-performance communications solutions. Once established in the role they will operate with a high degree of autonomy while receiving strategic guidance from Engineering Management.

Strong written and verbal communication skills are essential including the ability to clearly articulate complex concepts such as modulation schemes signal processing pipelines and radio system behaviour to both technical and non-technical stakeholders.

A few of our employee benefits are:

• Half day finish on a Friday or 9/80 working schedule available
• 25 days holiday per year (plus bank holidays) increasing with long service and with the opportunity to buy/sell up to 5 days
• Private medical insurance with optional family cover
• Pension scheme of up to 8% employer contribution
• Life Assurance 4x salary (flexible up to 10x)
• Group income protection
• Flexible opt-in extras such as a health care cash plan dental insurance gym membership critical illness cover cycle to work scheme travel insurance and electric car scheme
• Employee Family Assistance Program providing mental health and wellbeing support
• Professional membership reimbursement (discretionary)

What the role will involve

The responsibilities of your role will include the following:

• Maintenance and enhancement of embedded software for existing tactical radio and communications systems including feature development aligned to evolving operational requirements.
• Design and implementation of real-time embedded software for radio waveforms including modulation/demodulation filtering synchronisation and error correction techniques.
• Development and optimisation of DSP algorithms for performance-critical applications such as signal detection channel estimation and interference mitigation.
• Implementation of software within Software Defined Radio (SDR) platforms including integration with RF front-end hardware.
• Design and development of application-level tools for modelling simulation analysis and test of communication systems.
• Translation of high-level system requirements into detailed software architectures and signal processing designs.
• Production of high-quality technical documentation including design specifications and algorithm descriptions.
• Maintenance and evolution of software development and test environments including signal analysis and debugging tools.

What youll bring

The role requires the following experience and skills:

• Bachelors or Masters degree in Software Engineering Electronic Engineering Communications Engineering or a related discipline
• Minimum of 7 to 10 years experience in a prior related role.
• Strong knowledge of digital signal processing (DSP) concepts and implementation (e.g. filtering FFTs modulation schemes coding techniques)
• Proficiency in C/C for embedded systems with additional experience in C# and/or Python for tooling simulation or analysis
• Experience with real-time embedded systems and performance-constrained environments
• Familiarity with modelling simulation and analysis tools (e.g. MATLAB/Simulink) for DSP and communications system design
• Experience with MBSE UML and system/software design tools (e.g. IBM Rhapsody DOORS)
• Excellent communication skills with the ability to convey complex signal processing and radio system concepts clearly
• Strong organisational and problem-solving skills
• Proficiency with Microsoft Office and engineering tools (e.g. MS Project SharePoint Jira)

Important to know

Due to the nature of our work many our roles require a UK nationality and the ability to obtain a security clearance. Applicants who accept a conditional offer of employment must meet the requirement of right to work in the UK and must meet eligibility requirements for access to classified information and will be subject to government security checks.
