Frontend Developer

Front-end Software Engineer, Marketing Projects

SecureFlag is a fast-growing London-based company with a mission to improve application security training for developers. We have created an innovative platform for developers to learn, practice, and internalize modern secure coding practices through real-world exercises.

Our objective is to offer highly immersive, intuitive training so attuned to the developer’s individual needs that the overall experience is genuinely natural and enjoyable and, as a result, directly helpful and immediately applicable to their everyday job.

Position

We’re hiring a hands-on Front-end Software Engineer to build and take ownership of marketing-related web projects, working closely with the Marketing team to evolve our web presence.

In this role, you’ll write production-quality code and own the technical delivery of projects such as landing pages, campaign pages, website updates, and other marketing content. You’ll also help plan and drive these projects from idea to release, defining scope, managing priorities, coordinating stakeholders, and working with external agencies where needed.

You’ll collaborate with marketing specialists, designers, and developers to ensure our digital experiences are fast, scalable, accessible, and aligned with our brand.

We support remote working in the UK and European Union with flexible working hours.

What you'll do

• Ship code daily: Implement features, fix bugs, and jump on hot-fixes to keep the website fast and reliable.
• Own marketing front-end projects: Take responsibility for the technical delivery of marketing-related web projects, from implementation and quality to performance, accessibility, and design-system usage.
• Own technical SEO health: Proactively monitor and improve the site's technical SEO like page speed, crawlability, structured data, meta tags, redirects, Core Web Vitals, flagging issues and opportunities to Marketing rather than waiting to be asked.
• Be framework-practical: Work in Angular 13 today and guide us toward modern patterns; React experience is welcome. What matters is your willingness to get your hands dirty and deliver.
• Use agentic coding: Use AI-assisted and agentic coding to speed up implementation, prototyping, testing, and iteration while maintaining high standards for quality, security, and maintainability.
• Connect Marketing and Engineering: Partner closely with Marketing, front-end, and other development teams to translate business needs into clear technical requirements and deliver high-quality web projects.
• Own UX/UI quality: Champion a holistic view of UX and UI, prototype quickly, validate with users, and ensure consistent, accessible experiences.
• Coordinate partners: Scope and manage external agencies and contractors; review their output for quality and maintainability.

What you’ll bring

• 4+ years of hands-on front-end experience building production web apps, better if in marketing-related roles.
• Strong software project ownership skills, with experience planning work, managing scope and priorities, coordinating with external agencies, and driving projects through to delivery with limited supervision.
• Working knowledge of technical SEO best practices (site performance, semantic HTML, structured data, crawlability). You don't need to be an SEO specialist, but you should be able to spot issues and suggest fixes without being asked.
• Strong proficiency in JavaScript/TypeScript, HTML5, CSS3, and Angular 13. Willingness to work with other frameworks as required.
• Solid grasp of UX concepts and UI design principles; experience with design systems and rapid prototyping.
• Familiarity with tooling such as Git, Docker, and CI/CD pipelines.
• Excellent English communication skills: able to distill complex topics and align cross-functional teams.
• Familiarity with static website generators such as Jekyll.
• Bonus: exposure to application security concepts or a strong interest in learning them.
