Role: Sr Full Stack Engineer

Location: Reston, VA

Requires: US Citizens/Green Card Holders

Job Description

Oteemo is looking for a Full-Stack Engineer to support a major application modernization initiative for our client. In this role, you will work closely with a UX/UI designer, product owners, and engineering teams to modernize a critical enterprise application by transforming legacy workflows into a scalable, intuitive, and cloud-ready experience. A core focus of this engagement is decomposing a monolithic frontend into a microfrontend architecture using Angular 20, enabling independent deployability, team autonomy, and long-term scalability. The ideal candidate is a hands-on engineer with strong front-end and back-end development skills, deep experience with Angular and microfrontend patterns, a background working in Agile environments, and a passion for building clean, reliable, and high-performing software.

Key Responsibilities

• Architect, implement, and maintain microfrontend solutions using Angular 20, leveraging module federation or similar composition strategies to enable independently deployable UI modules.
• Work with UX/UI designers to translate modern designs and user journeys into high-quality, responsive interfaces built on Angular 20's latest primitives (signals, standalone components, deferred loading).
• Define and enforce microfrontend integration contracts, shell application design, and shared library standards across teams.
• Implement full-stack features, including front-end components, APIs, integrations, and back-end business logic.
• Modernize and refactor legacy application components into modern Angular-based frameworks and microfrontend architectures.
• Ensure all development aligns with security, compliance, and quality standards.
• Contribute to automated testing frameworks, including unit, integration, and regression testing, with coverage across microfrontend boundaries.
• Collaborate with DevOps and platform engineering teams to support CI/CD pipelines configured for independent microfrontend builds and deployments.
• Participate in Agile ceremonies—stand-ups, sprint planning, grooming, and reviews.
• Provide guidance on best practices, design patterns, and modernization techniques, with particular depth in Angular and microfrontend ecosystems.
• Document technical decisions, microfrontend integration workflows, and code to support long-term maintainability.

Qualificati

• 5+ years of full-stack software engineering experience
• Strong, hands-on Angular expertise (Angular 15+; Angular 20 preferred), including signals-based reactivity, standalone components, and the modern Angular CLI toolchain
• Demonstrated experience designing or implementing microfrontend architectures, including module federation (Webpack/Native), shell/remote application patterns, and cross-microfrontend communication strategies.
• Strong back-end experience (e.g., Java, .NET, Node.js, or similar).
• Hands-on experience building and consuming RESTful APIs'
• Experience working with cloud environments (AWS preferred)
• Proficiency with Git, CI/CD pipelines, and modern DevOps practices — including pipelines structured for independent microfrontend deployments.
• Solid understanding of software engineering best practices and design patterns.
• Experience collaborating with UX/UI designers and product teams.
• Strong communication skills and ability to work in a client-facing environment.

Preferred Qualifications:

• Experience leading or contributing to enterprise-scale frontend modernization, particularly monolith-to-microfrontend migrations.
• Familiarity with Angular 20 features including zoneless change detection, incremental hydration, and signal-based inputs/outputs.
• Familiarity with cloud-native architectures, microservices, or containerization (Docker, Kubernetes), especially as they relate to microfrontend hosting and orchestration.
• Exposure to financial services or regulated environments
• Experience with accessibility and usability standards (WCAG 2.x)
• Familiarity with relational databases, specifically PostgreSQL
• Experience with shared component libraries, design systems, or cross-team UI governance in a microfrontend context.
• Document technical decisions, code, and integration workflows to support long-term maintainability.
