Senior RF Engineer (Outdoor) in London

About The Role

As a Senior RF Engineer, the candidate will support the design, deployment and optimisation of our wireless mobile solutions across the HS2 project.

The Senior RF Engineer will work in a multi-discipline design team to design solutions that meet customers’ needs.

You will lead the cellular RF design of trackside macro cell sites serving millions of passengers every year.

• What You’ll Be Doing
• Carry out RF design for trackside macro cellular site infrastructure including antennas, RF feeders, RET control and remote radio installations.
• Perform RF modelling, link budgets and design using Atoll and other planning tools, including creation of coverage/quality simulations and throughput estimations.
• Modify clutter/DTM data as required to model the future final configuration of HS2 to ensure simulation accuracy.
• Perform iterative system optimisation to ensure RF quality is maximised, and handovers are optimal for the high‑speed rail environment.
• Review results, drawings and reports conducted by others.
• Collaborate with UK MNOs to co‑ordinate site design and parameters.

Lead optimisation activities to manage interference from external macro sites and minimise capture of unwanted external users.

• Aid in the development of bespoke antenna solutions by defining requirements performance parameters required to meet the system requirement.
• Develop design criteria/requirements, system dimensioning, link budget and traffic analysis.
• Create low level designs including Bills of Materials, cable schedules and detailed system configuration diagrams, ensuring costs are closely controlled throughout the design process.
• Understand the wider context of the design and ensure external interfaces are considered working with other team members to implement an integrated design.
• Ensure designs are dimensioned for current demand and scalable to adapt for future growth and changes in MNO requirements.
• Participate in equipment co‑ordination sessions with HS2 stakeholders and partners ensuring the needs of the RF design are represented in decision‑making and minimise design change.
• Complete RAMS and abide by company H&S policy.
• Work with project managers and co‑ordinators to deliver projects on time and on budget.
• Liaise with customers, presenting designs to clients, stakeholders and project teams.
• Complete any Handover Packs, Post Integration Reports and Design Reports on agreed timescales and report templates.
• Provide estimates on resources required for particular tasks.
• Updating any internal reporting system as required.
• Familiarisation of all company documentation, especially ISO procedures.

This role requires 2 days per week located in Birmingham.

• What You’ll Bring
• Experience RF planning, designing mast installations and optimising outdoor coverage solutions, ideally with background at an MNO.
• Prior experience of providing coverage solutions to rail networks would be advantageous.
• Knowledge of UK or IE mobile network architecture models and standards.
• Experience of designing DAS equipment rooms, including MNO equipment requirements, dimensioning DAS head end, and defining electrical and cooling loads.
• Experience of testing methodologies, test tools such as scanners and test phones (TEMS, NEMO).
• Advanced knowledge in RF and performance optimisation.
• Advanced knowledge of 3GPP standards especially relating to high‑speed rail scenarios and its impact on RAN performance.
• Advanced knowledge of radio propagation models, fade margins and other environmental factors impacting RF coverage.
• Good knowledge of Radio Link Budgets.

Benefits

• Flexible working opportunities.
• Parental leave with up to 20 weeks paid at full salary.
• Holiday allowance starting at 25 days rising with length of service.
• 4 days off each year to volunteer.
