Remote jobs in Europe

This is a part-time, remote, contract role for a Freelance Web Developer. You will build and maintain client websites in Webflow and WordPress, including full site builds, service and industry pages, landing pages, case study templates, and CMS work, supporting our clients' goals across multiple accounts. You will turn designs into responsive, fast-loading pages, wire up integrations and tracking, and collaborate with our creative and marketing teams on builds that connect to real campaign goals.

This is a largely async role. You will mostly work on your own schedule, so we want someone serious and capable who shows up reliably, manages their own work, and brings a strong point of view on what makes a site fast, clean, and built to last. We care about work that performs in the real world, not builds that look fine in the preview and fall apart on a phone.

This is also not a drag-and-drop, template-and-pray role. We expect you to use AI fluently as a tool, but the build has to be solid, the code clean, and the structure intentional. If your sites are bloated, slow, or held together with workarounds you can't explain, this is not the fit

What you'll do

- Build and maintain Webflow and WordPress sites that are responsive, fast, and structured properly, from full builds to landing pages, service pages, and CMS work.

- Turn Figma designs into pixel-accurate, mobile-first pages that look as good on a phone as they do on desktop.

- Wire up integrations and tracking, including HubSpot forms, GA4, and Google Tag Manager, so every site captures and measures what it should.

- Manage builds across several client accounts at once, switching platform, context, and brand cleanly between them.

- Handle the technical housekeeping that keeps a site healthy, including page speed, accessibility, schema, and clean URL structure.

- Drop into custom HTML, CSS, and light JavaScript, plus PHP on the WordPress side, when the platform alone won't get it done, and hit deadlines without hand-holding.

Part-time, remote, contract role for a Freelance Graphic Designer. You'll create work across brand, digital, and marketing: social graphics, ad creative, web and landing page visuals, lead-gen magnets, and pitch decks across multiple accounts. You'll design, art-direct, and produce polished, on-brand assets tied to real campaign goals.

This is a largely async role. You'll work on your own schedule, so we want someone reliable who manages their own work and has a strong point of view on what makes design good. We care about work that gets remembered, not assets that look like everyone else's.

This is not a drag-a-template-into-Canva role. Use AI fluently as a tool, but the work has to show real taste, craft, and intention. If your designs look generic or templated, this isn't the fit.

What you'll do

Design the full range, from brand identity and social to ad creative, web visuals, lead-gen magnets, and pitch decks.

Switch cleanly across client brands without losing each brand's visual system.

Build ad creative for Meta, LinkedIn, and Google that stops the scroll 

and earns the click.

Design lead-gen assets like ebooks, guides, and one-pagers that feel premium and on-brand.

Source and art-direct imagery that's conceptual and editorial, not generic stock.

Deliver production-ready files and hit deadlines reliably.

Qualifications

Strong portfolio across brand, digital, and marketing with range and taste

Expert in Figma, strong in Adobe Illustrator and Photoshop

Strong grasp of typography, layout, hierarchy, and brand systems

Experience designing for paid social and display, with an instinct for what performs

Fluency with AI design tools, paired with the judgment to keep work original

Comfort building and handing off editable Canva templates for clients

Meticulous about detail and QA your own files before shipping

Able to work independently and meet deadlines in a fast-paced async environment

Degree in Graphic Design or related field preferred, or equivalent experience

We are looking for an Ethical Hacker / Penetration Tester who can work closely with QA (or as a part time QA), engineering, and product teams to test web applications, APIs, authentication flows, permissions, infrastructure exposure, and overall application security.

This is a hands-on role. The main expectation is to find real risks, reproduce them clearly, document them properly, and help the engineering team validate that fixes are effective.

Role

We are looking for a Security QA Engineer / Ethical Hacker / Penetration Tester who will take ownership of security testing across application, API, and platform layers.

This person should be comfortable working as part of a QA-oriented delivery process while bringing deeper security expertise into the team. The role requires practical knowledge of penetration testing, vulnerability assessment, secure testing methods, and clear communication with developers.

Key Responsibilities

• Perform manual security testing of web applications, APIs, user flows, and admin panels.
• Conduct penetration testing against staging and production-like environments.
• Identify, reproduce, document, and validate security vulnerabilities.
• Test authentication, authorization, permissions, session management, password flows, and access-control logic.

• Practical experience with authentication and authorization testing.
• Ability to discover, reproduce, and explain vulnerabilities clearly.
• Experience using security testing tools such as Burp Suite, OWASP ZAP, Nmap, Wireshark, Metasploit, or similar.
• Understanding of HTTP, HTTPS, cookies, headers, sessions, JWT, OAuth2, MFA, and role-based access control.
• Ability to write simple scripts or proof-of-concept checks when needed, preferably in Python.
• Strong documentation skills and ability to produce actionable vulnerability reports.
• Good communication skills and ability to work directly with engineering and QA teams.
• Upper-intermediate or better English for written and spoken communication.

Nice to Have

About the Role

We are transitioning from React Native to fully native development: Swift/SwiftUI for iOS and Kotlin/Jetpack Compose for Android. We are looking for a Senior Mobile Engineer who will take ownership of both platforms and lead the migration effort.

• Lead the migration from React Native to SwiftUI and Jetpack Compose.
• Build paywalls, subscriptions, and monetization features using RevenueCat, StoreKit 2, and Google Play Billing.
• Develop AI-powered features, including chat, response streaming, and LLM integrations.
• Improve application performance, stability, and overall user experience.
• Manage App Store and Google Play releases.
• Leverage AI agents to accelerate development and maintain two codebases efficiently.

Our Ideal Candidate

• Has 5+ years of experience in mobile development.
• Is confident working with Swift/SwiftUI and Kotlin/Jetpack Compose.
• Has published apps in both the App Store and Google Play.
• Uses AI tools as part of their daily development workflow.
• Has experience with subscriptions, payment systems, and monetization.

• Has English proficiency at a B2 level or higher.

   

Nice to Have

• RevenueCat.

• Experience with fintech or SaaS products.

• Experience building custom AI agents, Claude Code Skills, or MCP servers.
