• Investigate complex, cross-layer failures and drive root-cause analysis with engineering.
• Mentor middle SDETs, review test designs, and set quality standards across the team.
• Partner with US-based development leads on shift-left practices, testability, and release readiness.

Required Qualifications:

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Python, including pytest, with deep understanding of OOP, software design principles, and test framework architecture.
• SQL & Data: Advanced SQL skills and strong understanding of relational and analytical data systems, including query execution internals.
• Data-intensive testing experience: Demonstrated experience testing data-intensive systems — query engines, ETL/ELT pipelines, streaming platforms, or analytical databases. Candidates with only web/UI QA backgrounds are not a fit.
• Testing experience: 5+ years in backend/system test automation, with demonstrated ownership of test strategy and infrastructure.
• CI/CD & DevOps: Solid experience architecting and maintaining Jenkins pipelines and test environments.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes (running workloads, debugging pods, deploying complex environments).
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.
• Leadership: Prior experience mentoring engineers, defining test strategy, or leading a QA/SDET function.

About Us
Mamma Mia Covers is a US-based DTC company serving the American and Canadian markets, and the exclusive distributor of the Italian brand PAULATO by GA.I.CO in the US and Canada. Since 2018, we've built a recognizable brand in the slipcover category — patented product, two sales channels: Shopify (DTC website) and Amazon US. Featured in Inc. 5000, team of 40+ people, own warehouses in the US.

We're expanding into new product lines, new categories, and a growing volume of visual content. Content is one of our core sales drivers, and we're looking for someone to join our design team and help generate visuals end to end.

The Role
This is a hands-on production role with real ownership. You'll work closely with our design team to create product visuals using AI generation tools, then bring them to commercial quality in Photoshop and Figma. You'll take a visual from idea to final, publish-ready asset — from AI generation through retouching, color correction, and layout.

What We Offer
Financial Stability: 

• $1,500/month — open to discussing a higher rate for strong candidates.
• Transparent, paid 2-month probation period 

Work Format: 

• Remote, full-time, flexible schedule

Learning & Development:

• Hands-on training in AI generation, Photoshop, and Figma tailored to our product
• Freedom to implement new tools and processes
• Professional courses and certifications as needed

Paid vacation: 

• 21 days + extra days off for important personal events

What You'll Do

AI-Assisted Content Creation

• Generate product visuals in different angles, interiors, and use-case scenes
• Create hero images, lifestyle content, and visuals for infographics
• Edit generated images: swap backgrounds, textures, and individual objects
• Locally edit specific areas of an image while keeping the rest of the scene intact (inpainting)
• Build sets of the same product in different colors and formats
• Test different generation approaches and pick the strongest result
• Upscale and prepare images at the resolution needed

Post-Production

• Retouching and fixing AI artifacts
• Color correction of the product against real photos and approved color swatches
• Adjust shape, proportions, perspective, lighting, and shadows for a natural result
• Recolor the product into collection colors while keeping texture, folds, and light consistent 
• Realistically add people, pets, or objects into finished scenes 
• Combining generations, photos, and 3D renders into one finished image 
• Preparing final images for the website, ads, and marketplaces

Graphic Design

• Building infographics, product cards, and comparison layouts in Figma
• Assembling layouts from generated, retouched, or 3D visuals
• Adapting layouts across different formats, platforms, and sizes
• Working within our existing visual style and brand guidelines

Task & Team Work

• Working from briefs, references, and product requirements
• Preparing a couple of options when a task calls for choosing a direction
• Revising work based on internal review feedback
• Tracking tasks, deadlines, and status updates in Asana

What We're Looking For
 Must have

• 1+ year of relevant experience (design, retouching, AI-generated content, or similar) — commercial, in-house, or strong freelance projects
• Practical experience generating and editing images with AI tools, including prompt writing and image-to-image / inpainting workflows
• Confident working knowledge of Photoshop: layers, masks, retouching, and color correction
• Comfortable working in Figma — able to assemble infographics and product layouts independently
• A portfolio with relevant examples, and the ability to explain your contribution and process
• Intermediate+ English — enough to work with interfaces, prompts, and technical documentation
• Willingness to complete a short test task close to real team work

Nice to have

• Any experience with video generation, motion design, or ComfyUI
• Any exposure to 3D (Blender)
• Understanding of fabrics, materials, and realistic texture rendering
• Experience with packaging, labels, instructions, or other printed materials
• Experience creating content for Amazon or other marketplaces
• Basic understanding of UX/UI and landing/sales page structure
• Skills in automating repetitive tasks in Photoshop, Figma, or ComfyUI

If this sounds like you:
You're curious about AI tools and not afraid to experiment. You take feedback well and use it to improve. You want to grow from executing tasks to owning your own visual work — and you're ready to put in the work to get there.
Apply and share a few examples of your work. We review every application personally and get back within 3 business days.
