Engagement Format

• Full-time preferred
• Remote
• Direct communication with founder / product owner

Ven Commerce Ltd. is an international technology company founded in 2012, with offices in the USA, Israel, and Ukraine. We operate across two domains: e-commerce (Talisa, talisa.com — a global personalized jewelry brand) and telehealth (Balto, balto.com). Our team of ~65 people works remotely across multiple countries.

We're looking for a Frontend Magento 2 Developer. Most of your time will be spent building responsive, fast-to-ship e-commerce interfaces, but you'll own the full feature, not just the UI layer.

We operate multiple Magento 2 / Luma-based storefronts — and we're giving this person real ownership of the frontend direction: technology choices and modernization roadmap. If you're opinionated about frontend and want to actually drive change rather than execute tickets, this is that role.

You'll work closely with cross-functional teams and are expected to leverage AI-assisted development tools as a natural part of your daily workflow.

We value getting things shipped and working. Pragmatism over perfection.

Responsibilities:

• Develop and maintain Magento 2 solutions with a strong focus on frontend: themes, UI components, performance, and conversion-oriented interfaces.
• Build responsive, accessible, user-friendly storefronts based on design mockups in close collaboration with the design and PM.
• Turn business requirements into working Magento 2 solutions.
• Take an active role in A/B testing of UI features — from implementation to analyzing results and iterating based on data.
• Participate in code reviews — giving and receiving feedback with a focus on maintainability, scalability, and frontend best practices.
• Collaborate with the other engineering teams on diagnosing production issues, performance bottlenecks, and security concerns.
• Stay current with Magento, PHP, and frontend ecosystem trends — and bring relevant ideas back to the team.

Qualifications:

• Strong hands-on experience with Magento 2 storefront development.
• Solid experience with Luma-based frontend work: themes, templates, layout XML, RequireJS, jQuery, JavaScript, HTML, LESS/CSS.
• Strong proficiency in TypeScript/ReactJS/JavaScript/ES6+
• Ability to collaborate well with product/design teams and turn requirements into working solutions.
• Hands-on experience with AI development tools — Claude Code, GitHub Copilot, Cursor, or similar — used regularly, not just occasionally.
• English - strong intermediate and higher.

Bonus points:

• Degree in Computer Science, Engineering, or a related field.
• Magento certification(s).
• Experience with unit/integration testing in Magento.
• NodeJS backend experience.

Benefits:

• Competitive compensation based on your experience and skills.
• Fully remote with a flexible schedule.
• 20 working days of paid vacation per year.
• Conferences, workshops, webinars, and training — we invest in your growth.
• Exposure to a wide variety of technologies and international projects.
• A team that values engineering quality, initiative, and smart use of modern tools.
