Frontend Developer Government information

What unique challenges might a Frontend Developer face when working on government projects?

Frontend Developers in government settings often encounter challenges related to strict accessibility and security requirements. Projects must comply with standards like WCAG for accessibility and follow government-mandated security protocols, which can introduce additional testing and development steps. Collaboration is typically cross-functional, involving policy experts, backend developers, and legal teams to ensure the final product meets all regulatory guidelines. These factors can extend timelines but also provide opportunities to develop expertise in high-impact, large-scale public service platforms.

What are the key skills and qualifications needed to thrive as a Frontend Developer in government, and why are they important?

To thrive as a Frontend Developer in government, you need a solid understanding of HTML, CSS, JavaScript, and accessibility standards, often supported by a relevant degree or equivalent experience. Familiarity with frameworks like React or Angular, version control systems such as Git, and compliance with government digital service guidelines are typically required. Strong problem-solving, attention to detail, and effective communication skills help you navigate collaborative projects and address diverse user needs. These competencies are critical to delivering secure, accessible, and user-friendly digital services that meet public sector requirements.

What are Frontend Developer Government jobs?

Frontend Developer Government jobs involve designing and implementing user interfaces for government websites and applications. These professionals ensure that digital services provided by government agencies are accessible, user-friendly, and compliant with relevant standards and regulations. They typically work with technologies like HTML, CSS, JavaScript, and various frameworks, collaborating with designers, backend developers, and stakeholders to deliver secure and efficient digital solutions for the public sector.

What is the difference between Frontend Developer Government vs Frontend Developer Non-Government?

AspectFrontend Developer GovernmentFrontend Developer Non-Government
Work EnvironmentPublic sector, government agencies, federal or state institutionsPrivate companies, startups, tech firms
Required CredentialsOften requires security clearances, government-specific certificationsStandard web development skills, certifications like HTML, CSS, JavaScript
Industry UsageGovernment projects, public service portals, official websitesCommercial products, consumer websites, enterprise solutions

Non-government Frontend Developers focus on commercial projects, emphasizing innovation and user experience. Both roles require strong frontend skills but differ mainly in work environment and credentials.

Frontend/UI Developer

Larus Technologies

Full-time

Medical, Dental, PTO

Posted 16 days ago

Job description

Job Summary
Full-time: 37.5 Hours per week, Monday to Friday
Location: Ottawa Office (Up to 3 days per week), 70 Laurier Ave West, Suite 310, Ottawa, ON K1P 5V5 and Ottawa-based Home Office, or, remote if located outside of the National Capital Region.
Reporting To: Director of Technology
Salary Range: $80,000-90,000
Type of Vacancy: New
We are looking for a UI/Frontend Developer to join the Larus team. You will design and build the interfaces through which military planners, analysts, and decision-makers make sense of complex, high-stakes information, interactive maps with NATO symbology, AI-powered workflows, rich text and code editors, and collaborative scenario planning tools. This is not a dashboard role: you will build decision-support tools where clarity and responsiveness directly impact outcomes. 
You will own features end-to-end, from gathering requirements with domain experts, through architecture and implementation, to shipping tested code. We expect you to have opinions about how frontend applications should be structured, and the experience to back them up. You will influence technical direction, mentor junior developers, and contribute to a codebase built on Feature-Sliced Design, headless UI primitives, and a custom design system. 
Key Responsibilities
  • Gather requirements from subject matter experts (including defence and military specialists), design user flows, and deliver working software; 
  • Architect and build complex, interactive React/TypeScript applications, geospatial interfaces, editors, data-dense views, and AI-integrated workflows; 
  • Design and maintain frontend state effectively, choosing the right patterns for client, server, and UI state; 
  • Build and extend a custom design system with headless primitives, scoped styling, and design tokens; 
  • Plan and conduct user studies (usability testing, A/B experiments, surveys) and use findings to iterate on designs; 
  • Write tests at every level, unit, integration, and end-to-end; and participate in code reviews; 
  • Present designs and demos to stakeholders; and 
  • Collaborate across disciplines, backend engineers, data scientists, and product managers, within an agile process. 

Qualifications
Some individuals are less likely to apply for a job unless they consider they are a perfect match. At Larus Technologies, we welcome motivated individuals to our diverse and inclusive workplace. Thus, if you are excited about this role but do not have every qualification, we encourage you to apply anyway.  
Expected qualifications include:
  • University degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience; 
  • Required to meet qualifications to obtain a Canadian Government security clearance (typically requires Canadian citizenship or permanent residency); 
  • At least 2 years of professional frontend development experience; 
  • Strong proficiency with React and TypeScript; 
  • Experience with modern state management (Zustand, Redux Toolkit, or similar) and server state patterns (TanStack Query, SWR, or equivalent); 
  • Experience with REST API integration and generated API clients; 
  • Experience writing unit, integration, and end-to-end tests (Vitest or Jest, Testing Library, Playwright or Cypress); 
  • Working knowledge of Git workflows and CI/CD pipelines; 
  • Strong communicator comfortable gathering requirements from domain experts and presenting to both technical and non-technical audiences; and 
  • Genuine interest in the product, understanding what we're building and why. 
Technical Skill Requirements, working knowledge of: 
  • GIS/geospatial interfaces-  MapLibre GL, Mapbox, Leaflet, or OpenLayers; GeoJSON and spatial analysis; 
  • Rich text editors (TipTap, ProseMirror, Slate) or code editors (CodeMirror); 
  • AI/ML-powered UX- Integrating LLM services, building chat interfaces, or designing human-in-the-loop features; 
  • User research- Planning usability studies, A/B tests, or surveys and translating findings into design improvements; 
  • Docker, Azure DevOps, or similar deployment and CI/CD platforms; 
  • Familiarity with Python for cross-team collaboration; 
Desired Higher-Level Skills:
These are not required, but will set you apart and open pathways to seniority:
  • Frontend architecture - modular methodologies (Feature-Sliced Design or similar), clear module boundaries, incremental migration planning; 
  • Design system ownership - design tokens, accessible components, visual consistency across themes and responsive layouts; 
  • UI/UX design and validation - wireframing and prototyping (Figma), designing and interpreting user studies, accessibility standards (WCAG 2.1 AA); 
  • Performance engineering - profiling React applications, bundle analysis, lazy loading, code splitting; 
  • Technical communication - design diagrams, architecture decision records, documentation; and 
  • Security awareness - OWASP top 10 frontend vulnerabilities and secure development practices. 
What You Can Expect
  • A collaborative team working on problems that matter in the defence and security domain; 
  • A modern tech stack - React 19, TypeScript, Zustand, TanStack Query, Vite, MapLibre GL, TipTap, Playwright, and a custom design system; 
  • A well-structured codebase following Feature-Sliced Design; 
  • Opportunities to shape architecture and technical direction; and 
  • Room to grow into more experienced roles 
Benefits 
  • Competitive compensation package; $80,000-90,000
  • Comprehensive Health and Dental insurance package; 
  • Competitive vacation and paid time off; 
  • Company-sponsored team-building events; and
  • Learning and development opportunities.
