Jobs at Djinni

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 Software Engineer to design, build, and own significant components of the core query engine of a large-scale distributed data platform. You will lead work across query planning, optimization, and execution — driving architectural decisions, mentoring middle engineers, and pushing the platform's performance and scalability boundaries across all major clouds.

This is a systems-level, backend engineering role focused on distributed data processing internals — not application development or CRUD services.

Responsibilities:

• Architect, design, and implement significant components of the query engine — planner, optimizer, execution operators, memory management, and data access layers.
• Write and review high-quality, performance-critical code in Java and/or C++.
• Own end-to-end delivery of features from technical design through production rollout.
• Drive performance optimization work — profiling, benchmarking, and eliminating bottlenecks in latency- and throughput-sensitive paths.
• Integrate deeply with columnar formats, open table formats, and connectivity drivers.
• Mentor middle engineers, lead code reviews, and set technical standards for the team.
• Contribute to CI/CD architecture and quality processes across Jenkins, containerization, and multi-cloud deployment (GCP, AWS, Azure via Kubernetes / Docker).
• Debug complex, cross-layer issues spanning query planning, distributed execution, memory management, and I/O.
• Partner with US-based engineering leads on design reviews, architectural decisions, and roadmap execution.

Required Qualifications:

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Java or C++, with deep understanding of OOP, systems design, memory management, and concurrency. Candidates strong in both are especially valued.
• SQL & Data: Advanced SQL skills and strong understanding of query execution internals — planning, optimization, and operator implementation.
• Data processing systems experience: Demonstrated experience building or extending data processing systems — query engines, distributed databases, ETL/ELT frameworks, or analytical platforms.
• Engineering experience: 5+ years in backend/systems software engineering, with a track record of owning significant components.
• CI/CD & DevOps: Solid experience with Jenkins and modern engineering workflows.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes.
• 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 rigorous 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, leading technical designs, or owning components end-to-end.

Desired Skills:

• Deep experience with Apache Arrow (columnar in-memory format).
• Hands-on experience with Apache Calcite (SQL parsing, planning, optimization framework).
• Experience with Gandiva or LLVM-based expression compilation and code generation.
• Experience with open table formats — Apache Iceberg, Delta Lake, or Hudi.
• Deep familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Deep understanding of query planning, optimization (cost-based, rule-based), and execution internals.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Track record of performance optimization at the systems level — profiling, vectorization, cache/memory-conscious design.
• Prior experience contributing to open-source data infrastructure projects.

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.

• 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.

Project about building the payments infrastructure that merchants have been waiting for. A single integration, intelligent routing, and the kind of reliability that lets businesses stop thinking about payments and get back to running their business.
The platform is real, the merchants are real, and the problems are hard. We're integrating multiple payment providers, routing transactions intelligently across them, and doing it in a way that's secure, scalable, and maintainable.

Core Development
● You build the services that make payments move. Sessions, routing, provider adapters, webhooks; you work across the core of the platform, end-to-end, from database schema through to deployment.
● You integrate payment providers properly. Clean adapter patterns, consistent error handling, and abstractions that make the tenth integration as maintainable as the firstYou write code that handles real money. That means understanding the failure modes, thinking about idempotency, and never cutting corners on correctness because correctness is the product.
● You contribute to architecture, not just implementation. You raise design concerns early, engage in technical decisions, and leave things better than you found them.

Quality & Performance
● You test what you build. Unit tests, integration tests, E2E tests, and an understanding of what each is actually for. You don't hand things to QA hoping for the best.
● You debug with rigour. When something goes wrong in production, you trace it, understand it, and fix the root cause, not just the symptom.
● You review code seriously. You give feedback that improves the codebase, and you take feedback the same way.Collaboration
● You work closely with the Tech Lead. You implement architectural decisions together and contribute meaningfully to technical design conversations.
● You engage with the product function. You take time to understand what you're building and why. Acceptance criteria exist to be understood.
● You show up to Agile ceremonies and contribute to them. Standups, sprint planning, retros; they only work if people engage honestly.
● You support the team across deployment, observability, and incident response. Shipping doesn't end at the PR merge.

How You’ll Be Successful
● What you ship works, and keeps working. Test coverage is real, regressions are rare, and you're not the source of production surprises.
● Provider integrations are clean and maintainable. The team can extend them without unpicking your decisions six months later.
● You raise concerns before they become problems. Whether it's a design risk, dependency, or edge case, you flag it early with context for the team to act.
● Your code reviews make the codebase better. Not just caught bugs, but clearer thinking, better abstractions, and a higher collective bar.
● The team trusts you across time zones. Async communication is clear, commitments are kept, and you don't go quiet when things get complicated.

Requirements:
 

• 2+ years of experience in a fast-paced environment with a proven track record of delivering results (we’re also happy to consider exceptional candidates with less experience)
• Strong problem-solving skills — you dive deep into problems, identify root causes, and drive solutions from start to finish
• Strong analytical skills — you’re comfortable working with product metrics, data-driven hypotheses, and spreadsheets
• Fast learner — you quickly adopt AI and automation tools to accelerate the design, development, and launch of new user journeys
• Upper-Intermediate (B2+) English

Responsibilities:

• Conduct market and user research to identify growth opportunities
• Generate and prioritize product growth hypotheses
• Design, run, and analyze growth experiments to validate hypotheses

Would be a plus:

• Entrepreneurial experience
• Degree from a top university (e.g. KSE, KNU, NaUKMA, UCU)
• Interest in psychology
