Senior DevOps Engineer (Contract) – Mobile CI/CD Pipeline Architecture & Migration We are looking for a highly experienced freelance or contract DevOps engineer to take full ownership of designing and delivering a modern CI/CD pipeline ecosystem for a complex mobile application platform. This is not a maintenance role. This is a greenfield rebuild inside a governed enterprise environment with strict guardrails, internal artifact repositories, and compliance requirements. You will be responsible for independently delivering production-ready pipelines that meet enterprise quality standards. The project is already in progress, but we need someone who can step in, take control, and drive it to completion with minimal supervision. Hourly $12. Long term contract engagement Project Overview We are rebuilding the full CI/CD infrastructure for a mobile application suite from first principles. The goal is to create industry-standard, enterprise-grade pipelines that are compliant, scalable, secure, and fully documented. The environment includes strict workflow guardrails, internal artifact repositories, reusable workflow standards, secrets management constraints, and policy enforcement (OPA-style validation). The pipelines must run within those constraints while maintaining high quality and observability. The scope includes: Android pipeline iOS pipeline Flutter pipeline Supporting tooling, automation scripts, and documentation Trial run readiness with fully operational workflows We are currently mid-migration and have partially unblocked the Android build environment. There are integration blockers related to artifact repositories, secrets management, and internal tool access. The new contractor will be expected to take full ownership of resolving these and delivering the full solution end-to-end. Key Responsibilities You will: Design and implement enterprise-grade CI/CD pipelines for Android, iOS, and Flutter applications Work within strict reusable workflow and guardrail systems Integrate internal artifact repositories (Artifactory/JFrog-style systems) Replace public dependency usage with compliant internal repositories Implement secure secrets handling using GitHub Actions secrets and/or enterprise vault systems Integrate build, linting, testing, static analysis, and deployment workflows Configure environment matrix builds and custom build environments (e.g., STAGE, PROD, QA, etc.) Resolve policy enforcement failures (e.g., OPA guardrails, repository compliance checks) Configure Play Store, App Store, Firebase, and distribution workflows Implement SonarQube, Detekt, SwiftLint, unit tests, and build validations Migrate legacy CI behavior into modern GitHub Actions workflows Create documentation suitable for trial run onboarding Proactively identify integration risks and request required system access in advance Deliver a fully working, end-to-end pipeline ecosystem ready for trial execution This role requires someone who can think ahead, anticipate system constraints, and proactively manage dependencies rather than reacting to pipeline failures after the fact. Required Technical Stack Strong expertise in: GitHub Actions (advanced reusable workflows, matrix builds, composite actions) Android CI/CD (Gradle, AGP, Kotlin builds) iOS CI/CD (Xcode builds, Swift, signing, provisioning) Flutter CI/CD JFrog / Artifactory integration Private dependency repository configuration Secrets management (GitHub Secrets, Vault, environment injection) OPA or policy-based pipeline enforcement SonarQube integration Static analysis tools (Detekt, SwiftLint, ktlint) Firebase App Distribution Play Store & App Store automation Fastlane Multi-environment build configuration (DEV, STAGE, PROD, etc.) Enterprise CI/CD governance patterns Nice to have: Experience migrating from GitLab CI to GitHub Actions Experience working in regulated or enterprise-restricted CI environments Experience designing CI systems from scratch under guardrails Expected Deliverables Fully operational Android CI/CD pipeline compliant with enterprise guardrails Fully operational iOS CI/CD pipeline Fully operational Flutter CI/CD pipeline Integrated static analysis, testing, and quality gates Secure and documented secrets management strategy Internal artifact repository integration fully configured Deployment automation to distribution platforms Setup scripts for build environments Clear documentation for onboarding and trial run execution All pipelines stable and production-ready before trial milestone The final output must be something that can be confidently presented to stakeholders as a premium, industry-standard solution — not just a stitched-together collection of reusable workflows. Ideal Candidate Profile Senior-level DevOps engineer with strong mobile CI/CD experience Comfortable operating independently and making architectural decisions Proactive communicator who flags risks early Able to work inside constrained enterprise environments Quality-focused — does not ship “good enough” Strong troubleshooting skills across build systems, dependency resolution, and CI orchestration Comfortable working under timeline pressure and delivering against milestones Engagement Details Contract / Freelance Remote Immediate start preferred Must be able to take full ownership and drive delivery independently

Hi there, I understand you want a greenfield rebuild of a full enterprise-grade mobile CI/CD pipeline for Android, iOS and Flutter, with strict guardrails, internal artifact repos, secrets management, and policy checks. I will design and deliver production-ready pipelines from the ground up, guided by reusable workflows, strong security, and clear documentation. I’ll start by mapping the current blockers (artifact access, secrets vaults, and internal tooling), then architect end-to-end pipelines (Android Gradle/AGP, iOS Xcode, Flutter), integrate Artifactory/JFrog, replace public deps with internal repos, implement OPA-style policy checks, and wire in SonarQube, Detekt, SwiftLint, and test gates. I’ll configure multi-environment builds (DEV/STAGE/PROD), automate Play/Store/App distributions, and establish robust monitoring and rollback strategies. Documentation will be prepared for trial onboarding, with a migration path from legacy CI to GitHub Actions, and a risk-aware rollout plan. 1) What is the current state of artifact repositories and access controls, and which repositories must be used for all builds? 2) Which internal secrets vaults and access methods are approved, and how should secrets be injected into CI workflows? 3) What corporate policies must be enforced (OPA, policy checks) and which guardrails are required for each pipeline stage? 4) Which distribution channels (Play Store, App Store, Firebase) must be automated, and what are the prerequisites for sign

⏱ Timeline: 55 days | Cost:$15 / huor |Proven experience I’ve successfully completed similar projects, specifically rebuilding mobile CI/CD ecosystems in governed enterprise environments using GitHub Actions, Artifactory, Vault, and policy-enforced workflows, and can provide relevant examples of my work. I’m confident I can deliver fully operational Android, iOS, and Flutter pipelines within 55 days. Based on my past experience, the real challenge is not writing workflows—it’s aligning pipelines with enterprise guardrails, artifact restrictions, and policy enforcement without constant breakage. In a recent GitLab-to-GitHub migration, early failures stemmed from unaligned internal repositories and OPA checks. By redesigning dependency resolution, secrets injection, and reusable workflow standards upfront, we achieved stable multi-environment builds and compliant deployments with zero post-trial blockers. To proceed, I’ll need access to current repositories, guardrail documentation, artifact repository structure, secrets management architecture, and clarification on milestone deadlines for the trial run. This is a straightforward ownership role for me, and I’m confident in delivering a production-ready, enterprise-grade CI/CD ecosystem. I’m ready to collaborate and start immediately — let’s make this happen.

Hi, As per my understanding: You need a Senior DevOps lead to take full ownership of a greenfield mobile CI/CD migration, resolving blockers in Android, iOS, and Flutter pipelines within a strictly governed enterprise environment. My approach: * Architecting modular GitHub Actions workflows integrated with internal JFrog repositories and OPA policy enforcement. * Implementing automated code-signing and secrets management using enterprise vault injection and Fastlane. * Hardening pipelines with SonarQube quality gates and multi-environment matrix deployments (QA/STAGE/PROD). Are the internal runner environments already provisioned for macOS builds? Also, is the existing OPA policy set accessible for pre-deployment validation? I will share my portfolio on your first message and am sure about the delivery after this first meeting. Best regards,
