Sr. Manager, Physical Security Design

About Cipher Digital

We are an industrial-scale data center construction and operations company. We allocate data center opportunities between bitcoin mining and other high performance computing services, such as AI. We continue to develop our pipeline of power capacity at high quality data center sites, either for bitcoin mining or HPC.Our best-in-class management team leverages expertise from the technology, fintech, energy, and finance domains, as well as deep experience related to cryptocurrencies and blockchain.

About Cipher Digital

Cipher Digital develops and operates industrial-scale data centers purpose-built for high-performance computing and AI workloads. We bring together deep expertise across power sourcing, real estate, engineering, construction, operations, and technology to deliver facilities engineered to the highest standards of precision and performance.

The Opportunity

Everything downstream starts with the design. Delivery quality, operational reliability, and the cost of getting it wrong are all decided on the drawing board.

Physical security at Cipher is led by three senior managers, each owning one phase of a project’s life: the Design lead owns the security design, the Integration lead owns installation, commissioning, and turnover, and the Operations lead owns the program once it is live.

This role owns the physical security design program end to end — translating threat and risk into a coherent, standardized, buildable design, and staying engaged through construction administration and record documentation so that what gets built matches design intent.

You will set the reference designs and standards our delivery teams and integrators build against, and you will own the design package to a level of completeness that lets integrators build directly from it, with no integrator-produced drawings and no shop drawings. That bar is deliberate and meeting it is the core of the job.

This is an individual contributor role at the outset, with the scope to build and lead a design team as Cipher grows.

Core Responsibilities

DESIGN STANDARDS & REFERENCE ARCHITECTURE

• Develop and maintain the corporate physical security design standards, reference designs, and technical guidelines that drive consistency and repeatability across the portfolio.
• Lead the technology strategy: platform and device standardization and sequences of operation (SOO), developed in partnership with the digital security and cybersecurity engineering functions so that what we specify is defensible on the network as well as at the door.
• Incorporate operational requirements and lessons learned from the Operations lead into the design standards, so each new reference design reflects what it actually takes to run a site.

OWNERSHIP OF THE DESIGN PACKAGE

• Own the physical security design lifecycle from concept and basis of design, through construction administration and record documentation, across new builds and expansions.
• Drive consistent, on-time production of every security design package handed to Construction.
• Hold every design package to a standard of completeness and accuracy that lets integrators build directly from it without integrator-produced drawings or shop drawings.
• Translate threat and vulnerability assessments into layered security designs appropriate to a critical-infrastructure environment, applying established principles such as defense in depth, CPTED, standoff, DORI, and the five Ds.

CROSS-DISCIPLINE COORDINATION & DESIGN REVIEW

• Own the security scope of coordination with the architectural, civil, structural, MEP, telecommunications, and IT/network engineering disciplines, so security is integrated early into designs rather than tacked on late.
• Run formal design reviews at each milestone (SD, DD, CD),…
