The Opportunity

RESPONSIBILITIES:

The responsibilities for this position may include, but are not limited to:

Under the direction of the Director of Design Engineering, the Design Engineering Senior Principal Mechanical Engineer provides technical leadership and accountability for mechanical engineering designs on capital projects and engineering services done at the South San Francisco, Dixon sites and other sites as requested. This role engages actively in the design and planning of upgrades to critical mechanical infrastructure, utilities and facility HVAC systems across a portfolio of 50+ buildings / ~6M square feet of space. This role is a respected industry expert and engages with the Roche internal and industry external network to learn, influence and collaborate on new technologies, best practices and standards, bringing this knowledge and expertise to bear so that project designs provide safe, efficient and reliable operations to Genentech customers.

Project Technical Analysis & Design Guidance:

The primary area of focus for this role will be supporting the execution of a portfolio of projects with technical input and technical coordination in the mechanical engineering area, including design guidance on HVAC, plumbing, fire protection, building controls, automation and energy management. The Senior Principal Mechanical Engineer will be assigned 2 - 3 large scale projects ($10M and above) and a portfolio of approximately ~20 projects at a time (ranging in size from $50K to $10M each

) for

which they will attend key design meetings and provide design input and technical options analysis. The projects will be executed by multi-disciplinary teams, and this role will need to align, coordinate input and influence key customers (R&D, Commercial, Pharmaceutical Technical Operations) and stakeholders (Site Operations, SHE and Security) on project designs.

Project Technical Analysis & Design Guidance, continued:

The Senior Principal Mechanical Engineer will also provide management and oversight of other Mechanical SMEs brought in as required to manage influx of mechanical related work. A key function of this role will also be to align the many project designs to Roche / Genentech and site specific standards, and to coordinate the scope done on these many small projects into a comprehensive strategy to address needs in this technical area across the site.

Lead Mechanical Design Standard Team:

SSF Design and Construction executes the design work on portfolio (less than $10M) projects using the services of three alliance engineering firms, each of whom has an assigned mechanical engineering lead. The role will lead a mechanical engineering design sub-team including the representatives of each of these three firms, along with representatives of Site Operations, Environment, Health and Safety (EH&S), and others. As defined by project needs, this team will be tasked with developing strategies for upgrading deficient areas of the campus through the project portfolio. This team may also engage in the development and review of design standards.

Site Specific Standards:

This role will be responsible for developing site specific mechanical design standards. Such standards will be based on Roche/Genentech corporate standards (including corporate "K" directives), but will be customized for the South San Francisco and Dixon sites. Development of site standards will involve effectively engaging, involving and influencing site leaders, site operations and customer groups, and will involve incorporating new industry technologies and concepts to advance the mechanical infrastructure of the site. Standards will be updated on a schedule agreed with management, and likely driven by upcoming portfolios of projects in a technical area for which such standards apply. This role will also be responsible for maintaining updated standards in an accessible online portal available to partner design firms and stakeholders.

Technical Leadership & IndustryNetwork Engagement:

The Senior Principal Mechanical Engineer will be the SSF site expert on industry HVAC/Plumbing, BAS trends and new technologies. As such, a key portion of the role is continuous learning, engagement with the Roche Engineering Network (technical experts within the Roche Global organization and other Roche sites) as well as outside industry organizations, including ASHRAE, ISPE and others. A portion of the role's time will be spent visiting other sites, attending (and occasionally presenting) at applicable conferences and industry events, and applying learned skills to the execution of projects at the SSF site.

Technical Leadership & IndustryNetwork Engagement, continued:

Additionally, a portion of the Senior Principal Mechanical Engineer's time will be spent supporting broad Design Engineering process improvement projects and LEAN initiatives, to improve the processes and functioning of the overall team.

Strategic Partnership & Innovation:

The Senior Principal Mechanical Engineer will be responsible for driving innovation across the design and construction of building systems, appropriately adopting technologies and delivery approaches which improve building systems performance, cost effectiveness, and reliability. This role will lead the development of a site-wide mechanical/electrical infrastructure strategy in partnership with Site Ops and Real Estate & Assets focusing on reducing total cost of ownership, improving performance, and ensuring current site needs are fully met while remaining adaptable to future demands. Additionally, for projects over $10M the role will work with internal and external partners to create and maintain a quality assurance and control program. This includes developing individual and team capabilities, collaborating with external partners to ensure qualified engineering resources are assigned to Genentech projects, and driving change when performance does not meet expectations. The Senior Principal Mechanical Engineer will also be the SSF site expert on industry trends and new technologies for performance-based commissioning and data analytics.
