Apply security best practices as a first-class concern in every feature you ship, and help raise the bar for authentication reliability, observability, and incident response across the team's services. * Code Quality & Engineering Craft: Write high-quality, maintainable code with strong test coverage, following team best practices around code reviews, CI/CD, and documentation. Contribute to the health of the codebase by identifying and addressing technical debt and improving shared components. * Third-Party & Internal Integrations: Integrate with MFA providers, email/SMS delivery services, internal identity services, and downstream relying parties. Proactively raise issues or opportunities discovered during integration work. * Cross-Functional Collaboration: Partner with Product, Design, Security, Identity, and adjacent engineering teams to deliver cohesive auth experiences. Participate actively in planning, retrospectives, and cross-team discussions - bringing your perspective to help shape the team's roadmap. ## Related Videos - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [The Laravel Core - Demystify The Beast](https://www.wearedevelopers.com/videos/98-the-laravel-core-demystify-the-beast) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [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) - [Slopquatting, API Keys, Fun with Fonts, Recruiters vs AI and more - The Best of LIVE 2025 - Part 2](https://www.wearedevelopers.com/videos/1765-slopquatting-api-keys-fun-with-fonts-recruiters-vs-ai-and-more-the-best-of-live-2025-part-2) - [Lessons learned from observing a billion API requests](https://www.wearedevelopers.com/videos/1574-lessons-learned-from-observing-a-billion-api-requests) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 119 - ❤️ === ❤️](https://www.wearedevelopers.com/magazine/454-dev-digest-119) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift)
