Staff Software Engineer

Guild Mortgage Company is hiring a Staff Engineer for its IT Factory, which builds shared engineering tools, software components, and platform capabilities for application delivery teams. The role designs, builds, maintains, and evolves reusable software and platform capabilities—primarily in the Microsoft .NET and Azure ecosystem—to improve developer experience, software quality, security, reliability, and maintainability across teams.

Responsibilities:

• Design, implement, test, and maintain reusable software libraries, services, developer tools, frameworks, and automation that address recurring needs across delivery teams
• Build and evolve Golden Paths: supported starter kits, reference implementations, and reusable delivery patterns that help teams develop, test, deploy, and support software consistently
• Apply hands-on full-stack engineering across application services, APIs, integrations, data access, developer interfaces, cloud workload configuration, deployment automation, and observability as needed for assigned capabilities
• Independently frame and resolve systemic engineering problems within agreed platform priorities. Align affected teams on technical approaches and carry solutions through implementation, adoption, and measured improvement
• Evaluate when to reuse, extend, integrate, or build a capability, balancing adoption needs, implementation effort, operating cost, and long-term maintenance. Avoid abstractions whose complexity exceeds their demonstrated value
• Develop and lead technical designs for assigned shared capabilities, contributing implementation evidence and recommendations to platform architectural direction
• Document significant decisions, validate assumptions through prototypes and testing, and surface design gaps before delivery commitments. The designated architect retains accountability for long-term architectural direction and consistency
• Develop reusable unit, integration, contract, and performance testing capabilities with QA and engineering partners. Build logging, metrics, tracing, diagnostic support, and resilient failure handling into shared assets
• Implement approved security, identity, secrets management, dependency management, and software supply chain requirements in reusable code and automation, working with the functions that own the applicable policies, tools, and controls
• Own engineering execution of the lifecycle for assigned assets, including maintenance, compatibility, releases, and migration support, within agreed priorities and architectural direction. Coordinate breaking changes and deprecation with architects, platform leadership, and affected teams
• Work with DevOps, SRE, and operational owners to validate deployment, rollback, monitoring, support documentation, and operational readiness
• Provide engineering support for incidents involving assigned assets and implement corrective improvements
• Work directly with consuming engineers to understand friction, test capabilities in real delivery conditions, and improve usability, documentation, integration, and self-service adoption
• Partner with developer enablement specialists on examples, technical walkthroughs, onboarding materials, and adoption feedback. Help teams use and contribute to shared capabilities with decreasing dependence on individual experts
• Identify recurring engineering constraints, duplicated solutions, technical debt, and gaps in shared capabilities. Recommend improvements to platform leadership and architects with evidence of likely benefit and implementation tradeoffs
• Provide estimates, technical dependencies, readiness evidence, and risks to the engineering lead responsible for coordinating platform delivery
• Make constraints and deviations explicit so execution plans reflect actual capability and capacity
• Mentor engineers and technical leads through pairing, design reviews, code reviews, and complex problem solving. Enable contributions to shared assets while preserving implementation quality and maintainability
• Use adoption feedback and engineering measures, such as startup effort, repeated defects, support burden, and delivery friction, to evaluate whether improvements deliver sustained value
• Evaluate and apply approved AI-assisted engineering tools where they improve development, testing, or documentation, retaining human accountability for correctness, security, and maintainability
• Perform other duties as assigned

Requirements:

• Minimum ten years of experience of progressive software engineering or closely related platform engineering experience, including demonstrated experience delivering and sustaining shared software or platform capabilities used by multiple teams
• Minimum three years supervisory or leadership experience
• At least three years providing senior technical leadership or cross-team engineering influence
• Deep hands-on proficiency in C# and .NET, with demonstrated ability to design, code, test, troubleshoot, and evolve complex production software
• Working proficiency with modern frontend technologies and their integration with backend services, sufficient to implement and support developer interfaces and full-stack reference applications
• Strong system design skills across APIs, distributed systems, asynchronous messaging, integration patterns, data access, and interface compatibility; ability to reason about cross-system behavior and downstream impact
• Production experience with Microsoft Azure and working knowledge of cloud compute, containers, data, identity, networking, security, and observability. Ability to implement workload components within established guardrails and delegated access
• Experience building reusable libraries, frameworks, developer tooling, automation, or shared services, including packaging, versioning, upgrades, documentation, and support for consuming teams
• Experience with Git, continuous integration and continuous delivery (CI/CD), automated testing, and repeatable environments. Hands-on proficiency with Terraform to implement and maintain infrastructure-as-code for assigned capabilities within established guardrails and delegated access
• Ability to diagnose performance, reliability, security, and integration problems using technical evidence and turn findings into sustainable engineering improvements
• Demonstrated ability to work independently on ambiguous technical problems, exercise sound judgment, and influence engineers and technical leaders across teams without personnel authority
• Clear written and verbal communication, effective mentoring, and the ability to explain technical decisions, constraints, and tradeoffs to technical and nontechnical audiences
• Excellent verbal and written communication skills required
• Highly organized and detail-oriented; ability to work in a fast-paced, metrics-driven environment required
• Proficiency in Microsoft Office Suite, Word, Excel, Wiki, collaborative cloud-based programs, and third-party software applications required
• Bachelors Degree in Computer Science, Information Technology, or related field strongly preferred
• Experience with internal developer platforms, supported development patterns, or shared engineering assets maintained through contributions from multiple teams. Experience treating developer capabilities as products with identified users, feedback, and ongoing support
• Experience with React and TypeScript, GitLab pipelines, OpenTelemetry, and Azure container, messaging, or managed application services
• Experience enabling phased modernization across .NET and existing PHP or other application stacks, including hybrid and legacy integrations
• Experience with secure software supply chains, automated control evidence, AI-assisted engineering, or software delivery in financial services or another regulated environment
