This role offers the opportunity to define the technical foundation of Blue Yonder’s mobile strategy, influence platform-wide decisions, and build a world-class enterprise mobile experience at scale. Qualifications - Mobile Engineering and Architecture - Min of 7+ years designing, building, and maintaining large-scale mobile applications using React Native, Swift, and Kotlin. - Proven track record of delivering visually polished and resilient apps with strong long-term maintainability. - Expertise designing scalable and flexible mobile architectures for iOS and Android using modern tools and best practices. - Experience evaluating and adopting cross-platform technologies to improve performance, maintainability, and developer experience. - Skilled in performance profiling, memory management, startup optimization, and overall app responsiveness at scale. Requirements - Technical Leadership, Systems, and Security - Senior or staff-level individual contributor experience providing architectural direction, conducting deep technical reviews, and mentoring engineers across distributed teams. - Strong understanding of backend systems and microservices, ideally with Node.js and TypeScript. - Skilled in REST API design, integration with cloud services, and working with NoSQL databases such as MongoDB. - Hands-on experience implementing authentication and identity solutions including AAD, OIDC, and evolving IAM platforms such as Gravitee. - Experience establishing engineering best practices, coding standards, architectural guardrails, and platform-wide patterns. - DevOps, Quality, and Cross-Functional Collaboration - Experience building CI and CD pipelines with GitHub Actions and managing mobile releases through App Store Connect and Google Play Console. - Strong advocate for quality with experience in unit, integration, and end-to-end testing using WebdriverIO, Appium, and SauceLabs. - Effective collaborator with product, UX and UI, backend, cloud, and platform teams. - Strong communicator able to translate business needs into scalable technical solutions and mobile experiences that deliver customer and enterprise value. Benefits - Comprehensive Medical, Dental and Vision - 401K with Matching - Flexible Time Off - Corporate Fitness Program - Wellbeing Days - A variety of voluntary benefits such as Legal Plans, Accident and Hospital Indemnity, Pet Insurance and much more

• Lead the platform engineering team: own its delivery, reliability commitments, health, and the growth and career development of its engineers, while remaining hands-on in the infrastructure and tooling yourself • Make LegitScript’s infrastructure auditable: own environment separation, change control, access management, and audit logging so that changes to production are traceable and defensible, and so the controls hold up to the Secure SDLC Policy, the Change Management Policy, and SOC 2 evidence requirements • Drive the migration to a standardized Kubernetes deployment path, delivered incrementally at natural replacement points while maintaining operational continuity for the teams and services that depend on it • Build and own the developer tooling and self-service deployment paths that let engineers ship application code to production without hand-managing infrastructure: the paved road, the golden paths, and the guardrails that make the safe way the easy way • Own and improve the CI/CD pipeline and its controls, including branch protection, required peer review, automated security and quality testing, and gated deployment, so the pipeline enforces our engineering and security standards at scale • Establish infrastructure-as-code standards in Terraform and bring manual or unmanaged production changes under version control and change management, eliminating the drift that creates technical debt and audit gaps • Reduce business-as-usual toil through automation and replatforming, so that volume growth stops being a headcount equation and engineering capacity shifts toward higher-value work • Own reliability, monitoring, alerting, and incident response for infrastructure as first-class concerns; serve as an escalation point and coordinate response for infrastructure incidents • Hold the boundary with the application platform: provide the infrastructure substrate and tooling that the application-platform and domain teams consume, and partner with the Staff Engineer who owns that platform rather than duplicating or absorbing their scope • Set and enforce the standard for infrastructure code quality, testing, documentation, and review, and raise the bar for the engineers and partners who work in the platform through clarity and example • Manage cloud cost and capacity deliberately, making the tradeoffs between performance, reliability, and spend explicit rather than incidental • Foster a culture of accountability, collaboration, and continuous improvement.

• Audit existing analytics applications to understand their underlying technology choices, data flows, and integration points • Design and implement integration patterns (APIs, event streams, shared data contracts) that allow siloed applications to interoperate without unnecessary rewrites • Evaluate build vs. consolidate vs. federate tradeoffs for components across the platform, documenting your rationale and driving alignment • Develop a deep understanding of existing data pipelines owned by distributed teams — including their data sources, transformation logic, and dependencies • Design and build a unified presentation layer that surfaces data from heterogeneous compute environments — including large-scale distributed systems (e.g., Spark) and traditional relational databases — in a consistent, accessible way • Deploy and manage platform services on cloud infrastructure (AWS preferred; Azure/GCP experience a plus)

• Build, maintain, and modernize the data infrastructure that Medium's product and engineering teams depend on • Own reliability of data infrastructure: Identify risks, instrument better observability, drive improvements that reduce toil • Bring a product mindset to platform ownership, partnering with engineers and stakeholders across teams • Contribute to the long-term platform roadmap, migrate end-of-life systems toward modern alternatives • Write and review Python-based tooling for pipeline orchestration, data quality, and infrastructure automation • Apply DevOps and SRE best practices • Mentor teammates and improve shared standards around reliability, documentation, and platform ergonomics • Attend Medium's twice-yearly, in-person offsites
