You will influence development teams, mentor engineers, and ensure secure, scalable delivery pipelines while collaborating with security, product, and operations to optimize performance and reliability.

Qualifications

• Bachelor’s degree in a relevant field.

Responsibilities

• Leads by example in setting complex code review guidelines and maintaining high quality code
• Designs systems with many dependencies and moving parts; the designs are scalable and efficient
• Debugs complex production issues
• Introduces best practices learned from cross-functional teams
• Evaluate and recommend CI/CD tools, frameworks, and technologies based on scalability, maintainability, integration capabilities, security, performance, and total cost of ownership.
• Define architectural standards and engineering guidelines for pipeline design, version control, branching strategies, build systems, deployment workflows, and release management.
• Identify architectural limitations and technical debt in existing delivery platforms and develop strategies to modernize and simplify the CI/CD ecosystem.
• Identify and eliminate bottlenecks across the software delivery lifecycle, including source code integration, compilation, dependency resolution, testing, artifact publishing, deployment, and release validation.
• Drive measurable improvements in build and pipeline execution times, feedback cycles, deployment frequency, release lead time, and overall developer productivity.
• Analyze pipeline execution data, failure patterns, resource utilization, and workflow dependencies to identify root causes and prioritize high-impact improvements.
• Embed security controls and compliance requirements throughout the CI/CD lifecycle, ensuring that security is integrated into development and delivery workflows rather than treated as a separate activity.
• Define and implement automated security scanning and policy enforcement, including SAST, SCA, secret detection, IaC scanning, container scanning, and dynamic testing where applicable.
• Integrate SBOM generation, artifact signing, provenance, dependency verification, and software supply chain security controls into build and release processes.
• Establish secure pipeline architecture and access controls, including secrets management, least-privilege permissions, protected deployment environments, and controlled access to build infrastructure.
• Implement policy-as-code and automated compliance validation to enforce engineering standards and security requirements consistently across delivery pipelines.
• Partner with security, compliance, and infrastructure stakeholders to address vulnerabilities, reduce delivery risks, and improve auditability and traceability.
• Lead by example in establishing engineering standards, complex code review guidelines, reusable implementation patterns, and high-quality automation practices.
• Own the design and architecture of CI/CD solutions and influence the broader software engineering architecture to support long-term scalability and maintainability.
• Define technical approaches for complex assignments where requirements, constraints, or implementation paths are not clearly established.
• Translate business and engineering objectives into technical strategies, architecture proposals, epics, stories, and measurable engineering outcomes.
• Collaborate with development, quality engineering, security, product, infrastructure, and operations stakeholders to align priorities and resolve cross-functional challenges.
• Introduce best practices and proven approaches from across engineering teams and the broader industry.
• Mentor senior and junior engineers in CI/CD architecture, DevSecOps, automation design, troubleshooting, testing methodologies, and continuous improvement.
• Influence technical decisions through design reviews, architecture discussions, technical documentation, and evidence-based recommendations without relying on formal people-management authority.
• Define technical strategies and implementation approaches for complex problems involving multiple systems, dependencies, platforms, and stakeholder requirements.
• Work with product and engineering stakeholders to clarify ambiguous requirements and identify practical, scalable solutions.
• Balance short-term delivery needs with long-term architectural improvements, maintainability, security, and operational risk.
• Independently prioritize and manage multiple complex initiatives while adapting to changing business and technical priorities.
• Approach recurring issues as opportunities to improve system design, automation, reliability, and engineering processes.
• Make informed technical decisions using data, experimentation, engineering judgment, and a clear understanding of customer and business impact.
