This role is responsible for enabling reliable, repeatable, secure, and compliant software delivery through modern DevSecOps practices, including CI/CD pipeline automation, Infrastructure as Code, container platform support, cloud security controls, automated testing and scanning, observability, release automation, and operational readiness. The Platform Engineer / DevSecOps Engineer will work closely with Product Owners, Scrum Masters, software engineers, solution architects, security teams, vendors, executive leadership, and Federal stakeholders to ensure the modernized platform is scalable, resilient, secure, maintainable, and aligned to program objectives. What You Will Do: We are seeking a strong Platform Engineer / DevSecOps Engineer to support the GrantSolutions platform modernization effort by building and improving the cloud engineering, automation, deployment, security, and operational capabilities needed to deliver modern software at scale. This role will help establish and operate the AWS-based platform patterns, shared DevSecOps services, pipelines, controls, and automation that enable multiple Scrum teams and vendor partners to deliver securely and consistently while supporting continuity of the legacy system throughout the transition. The Platform Engineer / DevSecOps Engineer will support cloud platform engineering, CI/CD implementation, infrastructure automation, security integration, environment management, release enablement, observability, and operational readiness in an iterative modernization environment. This individual will help deliver a secure and automated engineering platform that enables new vendor-delivered capabilities to integrate with legacy components as the modernized platform is built out over time. The role requires hands-on AWS cloud experience, strong automation skills, practical DevSecOps judgment, and close collaboration with Product Owners, Scrum Masters, project managers, solution architects, security teams, vendors, executive leadership, and Federal stakeholders to align platform delivery with architecture standards, governance expectations, release readiness, compliance requirements, and long-term modernization objectives. * Design, build, automate, secure, and operate AWS cloud platform capabilities that support a large-scale GrantSolutions platform modernization program delivered through iterative agile execution. * Implement and maintain modern DevSecOps practices, including secure CI/CD pipelines, automated build and deployment workflows, quality gates, vulnerability scanning, secrets management, policy enforcement, and release automation. * Develop, maintain, and improve Infrastructure as Code using tools such as Terraform, AWS CloudFormation, AWS CDK, or comparable technologies to support repeatable, auditable, and compliant environment provisioning. * Support cloud-native application delivery patterns using AWS services, container platforms, serverless services, managed databases, networking, identity and access management, logging, monitoring, and security services. * Partner with software engineering teams to standardize reusable pipeline templates, deployment patterns, environment configurations, shared libraries, and automation scripts that improve delivery speed, consistency, and reliability. * Embed security early and continuously across the software delivery lifecycle through automated static analysis, dependency scanning, container/image scanning, infrastructure scanning, configuration validation, and compliance evidence generation. * Implement and support observability practices, including centralized logging, metrics, dashboards, alerts, tracing, operational health checks, and production readiness monitoring across modernized and legacy-integrated capabilities. * Support secure environment management, including configuration management, access control, network segmentation, encryption, secrets handling, backup considerations, disaster recovery support, and change/release coordination. * Collaborate with solution architects, security teams, vendors, and Federal stakeholders to ensure platform capabilities align with enterprise architecture guidance, FedRAMP Moderate expectations, NIST controls, governance standards, and program security requirements. * Troubleshoot platform, pipeline, deployment, integration, performance, and operational issues; identify root causes; implement automation or process improvements; and support continuous improvement of the engineering platform. ## Related Videos - [Enabling automated 1-click customer deployments with built-in quality and security](https://www.wearedevelopers.com/videos/83-enabling-automated-1-click-customer-deployments-with-built-in-quality-and-security) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again)
