Software Engineering – Front-End

We are seeking a Senior Front-End Software Engineer to build web and desktop user interfaces for scientific, laboratory, and instrument-related software. This front-end-focused individual contributor will own architecture and delivery using Angular, TypeScript, RxJS, and Electron. The role combines hands-on development, automated testing, and production-quality engineering in a complex enterprise environment, with Python as a supporting skill for automation and tooling.

·       Design, develop, and maintain Angular/TypeScript web applications and Electron desktop applications for data-driven and workflow-oriented scenarios.

·       Own front-end architecture, component boundaries, state management, and reusable components, services, and shared libraries; apply SOLID principles and clear separation of concerns.

·       Integrate REST APIs and back-end/native services with authentication, asynchronous requests, error handling, and data transformation; implement secure Electron main/renderer communication.

·       Build responsive, accessible, and usable interfaces; diagnose performance, reliability, browser/runtime compatibility, API, and desktop integration issues.

·       Own automated quality through unit, component, integration, API, and end-to-end tests; contribute to CI/CD pipelines and automated quality gates.

·       Lead technical design and code reviews, establish engineering practices, explain trade-offs, and mentor engineers; collaborate with back-end, UX, quality, product, application science, and distributed teams.

·       Own features from design through implementation, testing, delivery, and support; identify and resolve maintainability, scalability, security, and reliability risks.

• Strong production experience with modern Angular and TypeScript, including components, directives, services, dependency injection, routing, route guards, Reactive Forms, and HttpClient.
• Strong RxJS and reactive programming skills, including Observables, operators, and error handling; practical knowledge of Angular lifecycle, change detection, lazy loading, modularization, and performance optimization.
• Strong TypeScript, JavaScript, HTML5, CSS/SCSS, DOM, and browser fundamentals, including interfaces, generics, advanced types, modules, async/await, and Promises.
• Hands-on production Electron experience, including main/renderer processes, IPC, preload scripts, contextBridge, back-end/native integration, security boundaries, and safe exposure of desktop capabilities.
• Experience designing reusable UI components or libraries and medium-to-large, multi-module applications across teams; sound understanding of component-based architecture, SOLID, design patterns, dependency management, RESTful APIs, responsive design, accessibility, usability, and browser compatibility.
• Hands-on automated testing across unit, component, integration, API, and end-to-end levels using frameworks such as Playwright, Cypress, Jest, Jasmine/Karma, or equivalent browser/desktop tools. Experience with maintainable test architecture, Page Object Model or equivalent abstractions, isolation, repeatability, mocking/stubbing, CI execution, and flaky-test troubleshooting is required; Playwright is preferred.
• Basic to intermediate Python for reading code, writing automation/test/utility scripts, processing JSON, CSV, files, and structured data, and using virtual environments and package management. Dedicated Python development expertise is not required.
• Ability to independently architect a moderately complex Angular/Electron application or major subsystem, explain trade-offs, and own production delivery and support; collaborate across functions, review complex changes, establish coding standards, and mentor developers.

• Electron packaging, distribution, auto-update strategies, installers, or Windows desktop integration.
• Storybook, Web Components, reusable component libraries, or Angular animations.
• Scientific, laboratory, medical-device, industrial automation, or instrument-control software; C#/.NET back-end or desktop integration.
• OAuth 2.0, OpenID Connect (OIDC), JWT, authentication, and authorization.
• Docker, Nginx, CI/CD, or containerized services; Git-based workflows, pull requests, code reviews, and Agile/Scrum development.
