Mechanical Engineer

The role will work on the HS2 project. HS2 is the UK’s new high speed rail network. It will be a catalyst for economic growth across Britain, freeing up space on the existing railways and connecting 8 out of the UK’s 10 biggest cities with fast, reliable and frequent high-speed services. Costain+ are delivering the HS2 Rail Systems Tunnel and Lineside Mechanical and Electrical Systems works for HS2, across the whole of the HS2 Route (HRS02). The scope includes the design, supply, manufacture, installation, testing, commissioning and maintenance (until handover) of the tunnel and lineside M&E systems which includes the tunnel services within the shafts, tunnels and cross-passages, and the low voltage electrical power distribution in the open route. Costain+ will further design, supply, install, test and commission the tunnel ventilation systems. HNC, HND, or Degree in Mechanical Engineering (or a related discipline)CSCS Card High standard of written and spoken English#LI-JO1Support the design, review, and implementation of Mechanical systems for HRS02 HS2 lineside worksInterface and coordinate with other HS2 Rail Systems contractors, including track, signalling, telecoms, OHLE, and HV powerReview technical documentation, drawings, and specificationsChair discipline specific meetings with HS2 and Costain+ partnersUndertake material selection and prepare associated technical approval and acceptance documentationAppreciation of programme of works and ability to feedback into relevant reporting mechanismsEnsure compliance with relevant standards, including UK rail industry standards and HS2 Works InformationIdentify, assess, and manage technical risks, supporting effective problem resolutionProduction of quality documentation, such as ITPs and installation verification check sheetsSupport assurance, quality, and safety processes throughout the project lifecycleInterface with installation and construction teams to ensure designs are practical, buildable, and aligned with site requirementsProvide engineering support during design, installation, testing, and commissioning activitiesOther ResponsibilitiesWork closely with the immediate Engineering team and Costain+ partners to coordinate requirements and programme deliveryLiaise with the procurement team to ensure appropriate Mechanical equipment is specified and sourcedMaintain close coordination with Design, Safety, Commercial and Planning teamsPromote and support the implementation of Costain values and behaviours across the projectKnowledge, Skills, and ExperienceEssentialPrevious experience working on rail infrastructure projects in the UKExperience in Mechanical engineering within large-scale infrastructure or rail systemsStrong understanding of Mechanical design principles and relevant UK rail industry standards (e.g. Network Rail standards, BS 9990, etc.)Good understanding of Tunnel Fire Main/ Tunnel Ventilation / Cross Passage Door design and installation in a rail environmentExperience working within a main contractor or major project environmentSound knowledge of Mechanical installation practices and associated equipmentDesirableExperience working on major UK rail projects (e.g. HS2, Network Rail)Knowledge and experience of Acoustics, Fire Stopping, M&E systems, or rail systems integrationFamiliarity with design and installation of metalwork structuresChartered or working towards professional accreditation (e.g. IEng/CEng)Full timePosting Date:
