About Us

Clayco is a full-service, turnkey real estate development, master planning, architecture, engineering, and construction firm that safely delivers clients across North America the highest quality solutions on time, on budget, and above and beyond expectations. With $8.1 billion in revenue for 2025, Clayco specializes in the "art and science of building," providing fast track, efficient solutions for mission critical, industrial, life sciences, power & energy, aviation, commercial, institutional, residential and sports & entertainment related building projects.

The Role We Want You For

Precon OS is Clayco's in-house preconstruction platform (Estimation, GC/GR, Data Manager, Program Management) and the future estimate source for E2B Hub. The foundation is sound, but an estimator cannot yet complete and issue an estimate end-to-end in the platform. Clayco is bringing in an external vendor to close that gap. This role owns the outcome: it directs vendor delivery, protects scope, resolves open decisions, and gets Precon OS to a production-ready MVP that Clayco can run without the vendor.

This is a delivery-governance role, not a coordination role. The work includes a mandatory validation phase, eleven work packages of uneven size and risk, a long list of unresolved Clayco decisions, and two technology stacks.

The Specifics of the Role

• Run the vendor engagement - Own the plan, cadence, RAID log and status reporting across all work packages. Hold the vendor to the Definition of Done: delivery is traceable requirements, passing tests and approved evidence, not hours consumed or sprints completed.
• Govern the validation phase (WP-0) - Drive the vendor's codebase and functional validation, then lead the re-baseline of scope, price and schedule against what is actually found. Hold the line against optimistic assumptions about how complete the Estimation module is.
• Manage scope and sequencing - Enforce the in-scope / out-of-scope boundary and the real dependencies: RBAC unblocks UAT, GC/GR authorization precedes the rate-engine cutover, lineage work follows the parity proof, and the E2B Hub re-platform follows the API contract.
• Close open decisions - Maintain the decision register (Program Management/Estimation coupling, authorization model, deploy access, stable role identity, E2B Hub override continuity and cutover approach, scale targets, audit retention). Put each in front of the right Clayco owner with a recommendation and a deadline.
• Own acceptance and quality gates - Run the traceability matrix and merge/acceptance gates: GC/GR byte-identical parity, arithmetic that reconciles to the cent, permission matrix with API-level redaction checks, concurrency, migrations, manual browser verification, and E2B Hub no-regression and read-only enforcement.
• Orchestrate UAT, beta and cutover - Schedule estimator, cost administrator and project director time; triage defects against agreed severity thresholds; plan training and cutover. Lead the final BO-1 acceptance run on a live project with the chief estimator.
• Clear Clayco-side dependencies - Get staging and production environments stood up, vendor repository, Okta and Azure access provisioned, and deploy-path questions settled, so the vendor is never blocked on Clayco.
• Coordinate across teams and stakeholders - Keep preconstruction leadership, Platform/Security, Data/BI, the E2B Hub team and any other module vendors aligned. Report clearly and early to executive sponsors on risk, scope change and budget.
• Manage budget and commercials - Track spend against the separately priced packages (WP-0, WP-10), process change requests, and approve invoices against accepted deliverables only.
• Secure the handover - Make sure architecture, API, runbook and administrator documentation are delivered and that Clayco engineers can deploy, diagnose and onboard unassisted (BO-8).

What Success Looks Like

• A nominated estimator produces a complete GMP-level estimate for a real project in Precon OS and issues a client-ready deliverable with no external spreadsheet step.
• Other Clayco applications consume estimate, catalog, GC/GR and program data through a documented, versioned API; E2B Hub reads from Precon OS with no regression and no write path.
• A new GC/GR rate year is published as configuration, with no migration or deploy, and legacy plan totals match byte-for-byte.
• UAT is unblocked, scope held, and Clayco runs the platform without vendor involvement.

Requirements

• 7+ years managing software delivery, including 3+ years running large, multi-workstream programs with an external development vendor.
• Proven record governing complex enterprise applications through discovery, build, UAT and cutover, including commercial oversight (SOW, change control, milestone acceptance).
• Comfortable with a modern engineering stack at the level needed to challenge a vendor: Python/FastAPI, React/TypeScript, PostgreSQL, Azure, CI/CD and database migrations. You do not need to write code, but you must read a pull request summary, a test report and an architecture decision with a critical eye.
• Strong requirements and traceability discipline; able to turn acceptance criteria into evidence and say no to “done” when it is not.
• Experience running decision logs and driving unresolved decisions to closure with senior stakeholders.
• Clear, direct communicator who can brief executives and estimators equally well.
• Background in construction, preconstruction estimating, cost data management or other financially rigorous domains (cost-to-the-cent reconciliation, markup and fee logic).
• Exposure to .NET, SQL Server and SignalR applications, or to data-source migrations in production systems with a rollback plan.
• Familiarity with RBAC and identity (Okta, Auth0, Azure AD), API productization (OpenAPI) and ERP or estimating integrations (e.g., Procore, JDE).
• PMP, PgMP, SAFe or equivalent certification; experience in Asana or similar work-management tools.
• Experience taking over or rescuing a partially built internal application.
