About the Client:

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

About the Role:

We are looking for a Senior SDET to lead the design of automated test frameworks and testing strategy for a large-scale distributed data platform. You will own the quality of the query engine, connectivity layer, and backend services end-to-end — from framework architecture through CI/CD infrastructure across all major clouds — and mentor middle engineers on the team.

This is a data-heavy, backend-focused role. We are not looking for web/UI QA engineers — the work centers on validating distributed query execution, data correctness at scale, connectivity drivers, and backend microservices.

Responsibilities:

• Architect, design, and evolve automated test frameworks in Python / pytest for backend services, REST APIs, and distributed data components.
• Define testing strategy for new features and platform components — coverage, risk assessment, and quality gates.
• Own end-to-end, integration, performance, and regression testing covering SQL query execution, data correctness at scale, and platform APIs.
• Lead performance and load testing efforts with JMeter, including workloads over JDBC / ODBC / Arrow Flight drivers.
• Design and validate large-scale data testing scenarios — query plans, result correctness across heterogeneous data sources, metadata consistency, and behavior under high concurrency.
• Own CI/CD test pipelines in Jenkins — architect, maintain, and continuously improve.
• Provision and manage test environments in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker; drive automation and reproducibility.
• 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.

Desired Skills:

• Deep experience testing REST APIs and backend microservices at scale.
• Hands-on with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Strong understanding of modern data lakehouse concepts, open table formats (Apache Iceberg), and data warehousing.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Performance testing with JMeter or comparable load-testing tools at production scale.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Deep understanding of query plan generation, query acceleration / materializations, and metadata integrity in distributed data systems.
• Prior experience leading a QA/SDET function in a data-platform or database engineering environment.

About Us

We are a US-founded early stage start-up with an R&D team located in Europe. Our mission is to make learning accessible, relevant, and individualized to keep up with the changing world. We are developing a personalized virtual trainer experience, integrating generative AI and learning engineering to build a VR simulator for immersive hands-on skills training. Our learning engineering approach customizes content and feedback in real-time, directly improving learning outcomes.

We're looking for a Senior Unity engineer to help build the client-side infrastructure of our training platform. This is not just one-off application work. You will build the client foundation that powers VR training simulations today, and additional client targets over time, connecting it to our server according to a defined client-server architecture. The role demands strong application architecture, on-device services, and performance optimization skills.

The Role

This is a hands-on individual contributor role focused on building and evolving key components of our platform's client-side architecture. You will build client infrastructure against a defined server-client architecture in which the server owns authoritative simulation state and logic, connecting the client to the server per spec and reflecting server-owned behavior faithfully on the device.

Key Responsibilities

• Own and drive key components of the Unity VR client architecture so they generalize across training simulations and, over time, additional client targets, rather than serving a single application.
• Build client-side infrastructure that connects to the server according to defined contracts and reflects server-owned state and behavior on the device.
• Co-design the client-server API with the backend, defining the data contracts.
• Develop tooling that supports content creators and other developers working on the platform.
• Use AI coding assistants as part of day-to-day development, and build and maintain the pipelines and validation that make their output reliable.
• Make pragmatic architectural decisions and manage technical priorities effectively in a fast-paced, ambiguous startup environment.

Requirements

• Demonstrated professional Unity and C# experience, ideally 5+ years, with a track record of shipping complex applications or products.
• A portfolio demonstrating experience architecting and refactoring large-scale Unity projects.
• Direct experience building for VR, in particular Meta Quest.
• A track record of building generic, reusable infrastructure and frameworks, not just one-off features.
• Comfort working within a defined client-server architecture and with established API contracts.
• A proactive and adaptable mindset suited for the dynamic and evolving environment of an early-stage startup.
• Excellent communication and collaboration skills in English, with experience working effectively in a remote, culturally diverse team.
• A genuine interest in using technology to enhance learning and education.

Nice To Have

• Experience targeting additional client platforms such as WebGL.
• Experience with data-driven or reactive component systems.

What We Offer

• A high-ownership role with direct influence on product direction, architecture, and user experience, and on company culture.
• A senior opportunity to build a platform from the ground up and contribute to its growth and commercialization.
• The flexibility of a fully remote position, with working hours flexible across European time zones rather than tied to US hours.

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.

What You'll Do

AI-Assisted Content Creation

• Generate product visuals in different angles, interiors, and use-case scenes

• 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
