About the Role

We are looking for a strong Digital Designer who can turn strategy, product information, customer insights, and creative briefs into high-quality designs that communicate clearly and drive action.

You will work across the entire e-commerce customer journey, including:

• Amazon and marketplace listings
• Shopify website design
• Landing pages and product pages
• UI design
• Paid social advertising
• Promotional and campaign assets
• Email and retention creative

You should have a strong understanding of visual hierarchy, e-commerce design, conversion principles, mobile-first design, and direct-response creative.

The ideal person is both creative and commercially minded. You care about whether a design looks great, but also whether the customer understands the message and takes action.

Key Responsibilities

E-commerce & Marketplace Design

• Design Amazon listing images, A+ Content, storefront graphics, comparison charts, infographics, and other marketplace assets.
• Translate product benefits, ingredients, use cases, reviews, and positioning into clear visual communication.
• Continuously improve listing creative based on customer feedback, performance data, and testing.

• Create clean, intuitive, mobile-first layouts that improve the customer journey.
• Work closely with the e-commerce/CRO team on website tests and conversion improvements.
• Turn briefs, wireframes, or ideas into polished designs ready for development.
• Maintain consistency across desktop and mobile experiences.

Paid Advertising Creative

• Design static and graphic-based creative for Meta, TikTok, and other paid channels.
• Create multiple creative variations for testing different hooks, offers, messaging, formats, and concepts.
• Adapt winning concepts into new iterations quickly.
• Work with the creative and performance teams to understand what is working and improve future designs.

Campaign & Retention Design

• Create promotional graphics for launches, offers, seasonal campaigns, and major sales events.
• Support email/SMS campaigns with on-brand, conversion-focused creative where required.
• Resize and adapt assets across channels while maintaining quality and consistency.

Brand Consistency

• Follow and help evolve MyMagicHealer's visual identity.
• Maintain consistent typography, layout, imagery, colors, product presentation, and design standards across channels.
• Organize design files and maintain clean working files that other team members can easily access and use.

What Success Looks Like

Within this role, you should be able to:

• Consistently deliver high-quality design work on deadline.
• Turn briefs into strong creative with minimal hand-holding.
• Produce designs that are visually strong while clearly communicating the intended message.
• Understand the difference between branding design and conversion-focused e-commerce design.
• Create multiple strong concepts rather than relying on one execution.
• Iterate quickly based on feedback and performance data.
• Maintain excellent attention to detail across every customer touchpoint.
• Improve the overall quality and consistency of MyMagicHealer's digital presence.

Required Qualifications

• Strong portfolio demonstrating e-commerce and digital design experience.

About us

Lime Vizio is an eCommerce company operating floral and gifting brands across the US and Canada. We’re looking for a CRM Email Marketing Manager to turn our customer base into a consistent source of repeat purchases and profitable growth.

About the role

You will own CRM and email marketing strategy, from identifying growth opportunities and planning customer journeys to evaluating results and driving improvements.

Your focus will be increasing retention, customer lifetime value, and revenue through relevant campaigns, segmentation, and automated lifecycle communications. You should be comfortable setting priorities independently and turning customer data into clear marketing decisions.

Key responsibilities

• Develop and own the CRM and email marketing roadmap aligned with business goals, customer behavior, and seasonal demand.
• Build customer segments based on purchase history, engagement, lifecycle stage, and buying occasions.
• Plan and improve lifecycle journeys, including welcome, cart recovery, post-purchase, repeat purchase, occasion reminders, and win-back flows.
• Own the email campaign calendar, audience selection, messaging direction, offers, and performance.
• Maintain a prioritized testing backlog covering segmentation, offers, content, timing, frequency, and customer journeys.
• Run structured A/B tests, document findings, and turn results into actionable decisions.
• Track CRM revenue, repeat purchase rate, customer lifetime value, and the contribution of automated flows.
• Explain performance changes through campaign, flow, segment, and cohort analysis.
• Protect deliverability and customer trust through list hygiene, relevant communications, and monitoring of complaints and unsubscribes.
• Coordinate with creative, technical, and marketing teams to deliver campaigns and automation accurately and on time.

• Proactively identify opportunities, flag risks, and recommend next steps.

   

What we’re looking for

• Hands-on experience in CRM, email marketing, or lifecycle marketing within eCommerce.
• Strong understanding of retention, customer journeys, segmentation, and commercial marketing principles.
• Proven examples of improving repeat purchases, CRM revenue, or customer lifetime value.
• Ability to interpret campaign and customer data, assess attribution limitations, and distinguish meaningful improvements from surface-level metrics.
• Experience designing A/B tests and applying the findings to future decisions.
• Sound commercial judgment: balancing revenue, margins, promotional intensity, and customer fatigue.
• Ability to write clear briefs and evaluate messaging, offers, and calls to action.
• Ownership, attention to detail, and the ability to move work forward without constant direction.

Experience with a specific CRM or email platform is not a prerequisite. Strong marketing judgment, CRM expertise, and the ability to work effectively with technical implementation support matter most.

What success looks like

• CRM delivers measurable growth in repeat purchases and profitable customer revenue.
• Automated journeys generate a meaningful, growing contribution to CRM performance.
• Testing consistently produces useful insights and informs priorities.
• Reporting clearly explains results, their drivers, and recommended actions.
• Revenue growth is supported by healthy deliverability and customer engagement.
• You independently manage the CRM roadmap and take responsibility for agreed outcomes.

Metamindz is a UK-based technical consultancy - CTO-led software development, fractional CTO services, and technical recruitment for startups and scaleups across the UK, US, and Middle East. Every project is run by real developers and CTOs rather than non-technical account managers, so engineers here work directly on real products and real technical problems.

We're looking for a Fullstack Engineer to join our work with UK-based smart locker technology company building software and hardware systems for automated collections, returns, and asset handovers.

This is a hands-on product engineering role where backend reliability matters as much as frontend quality. You'll be working across the application stack, while also dealing with the interesting boundary between software and physical hardware. The role is best suited to someone who is technically solid, easy to work with, and comfortable taking ownership without needing to be micromanaged.

Who we're looking for:

• Strong backend experience first - Ruby on Rails is the key requirement
• Solid fullstack experience with React and Next.js
• Comfortable working with ERB templates, as they are still heavily used in the product
• Good understanding of databases and data integrity - PostgreSQL preferred, MySQL also fine
• Basic AWS and DevOps knowledge - you should be comfortable deploying and operating applications, but you won't be expected to rebuild Kubernetes clusters
• Good understanding of APIs and integrations, with the ability to reason about how software communicates with external systems and hardware
• 3-5+ years of commercial development experience is ideal; strong candidates with around 2 years can also be considered based on their experience and client feedback
• Strong communication and a good attitude are essential - we'd take a great communicator who solves problems over a more senior developer who is difficult to work with
• Comfortable working independently, responding reliably, and collaborating closely with the wider team

What you'll work on:

• Building and maintaining Ruby on Rails backend functionality
• Working across React, Next.js and ERB-based frontend code
• Designing and working with APIs that connect the platform to external systems and hardware
• Working with PostgreSQL and ensuring data remains reliable and consistent
• Deploying and maintaining applications in AWS
• Debugging issues across the full stack, from frontend behaviour through to backend logic, databases and hardware integrations
• Working on features that interact with real-world locker hardware, where software reliability has a direct operational impact
• Collaborating with the development team to solve problems and ship production software

Nice to have:

• MQTT or other messaging / IoT experience
• Previous experience working with connected hardware or physical devices
• Experience with other cloud platforms or DevOps tooling
• Experience working in a startup, agency or product consultancy environment

What we offer:

• The opportunity to work on a real product combining software and connected hardware
• Direct collaboration with experienced engineers and CTOs
• Real production work used across retail, warehouse and workplace environments
• A role with genuine ownership across the stack rather than a narrow frontend or backend position
• A technically interesting mix of web development, APIs, databases, cloud infrastructure and hardware integrations
• A collaborative environment where communication and problem-solving matter as much as technical seniority
• The opportunity to work on a product where software directly controls and tracks real-world operations
