Jobs at Djinni

We're looking for a Senior Data Platform Engineer to architect and operate data infrastructure across the client's hybrid cloud (AWS + GCP). 

Our client is a fast-growing European fintech company in the business spend management space — corporate cards and related financial products — serving SME and mid-sized business customers across the EU and UK, in a regulated environment with GDPR compliance obligations. Engineering is organized into cross-functional squads, with platform/enabling teams providing shared tooling horizontally.

The client is currently in an AI transformation phase, transitioning to Agentic AI Development, and is seeking a Senior Data Platform Engineer to support this transformation. They run a hybrid cloud setup: AWS-first overall, with GCP (BigQuery as primary data warehouse) for data platform and analytics workloads. The Data Platform Engineer will set up and maintain the data infrastructure (data lakes, pipelines, IAM, observability, cost optimisation) that Data Engineers then use to operate on data. Work is expected to be a mix of existing codebase and new functionality.

Responsibilities:

• Architect and operate data infrastructure across hybrid cloud (AWS + GCP).
• Design data lakes; orchestrate pipelines (e.g. Airflow).
• Manage IAM/access management and cost optimisation.
• Maintain observability across the data platform.
• Work with both BigQuery and AWS data lake patterns (Athena, S3, Glue).
• Multiply the output and quality of the squad you join, and share patterns/practice beyond your immediate team so adoption compounds across the organisation.

• Embed directly into a client squad as a hands-on Individual Contributor (not a coaching/managerial role).

   

Requirements:

• Hybrid cloud: AWS and GCP.
• Data lake design.
• Orchestration, e.g. Airflow.
• IAM/access management.
• Cost optimisation.
• Observability.
• BigQuery and AWS data lake patterns (Athena, S3, Glue).
• Python.

Nice to have:

• Terraform.
• Familiarity with fintech-specific domains such as fraud/AML, transaction monitoring, and regulatory compliance.

Our client is a leading online car marketplace group operating across Europe and North America, bringing together market-leading brands to shape the future of our industry by combining the best of both regions.

About the Role: Join our client's Platform Engineering team, where they build the internal platform that 600+ developers rely on to ship software quickly and safely: centralized Kubernetes, managed CI/CD, project templates, and developer tooling running on AWS.
A big part of that today is making developers more productive with AI — secure environments for AI coding tools, AI-assisted CI, agentic workflows on AWS (Bedrock, Agent Core), and MCP-based integrations. AI is the means, not the end: what we care about is a faster, smoother day-to-day for every engineer.

We are looking for a Senior Platform Engineer who works fluently with modern AI tooling and uses it to move fast — someone who'd rather build something and learn from it than research it forever, and who brings solid infrastructure/AWS fundamentals along with the product thinking and communication skills to own a topic end to end.

Responsibilities: 

• Build and operate the internal AI platform: secure AI coding environments, AI in CI/CD, agentic workflows on AWS (Bedrock / Agent Core), and reusable building blocks teams adopt by default.
• Own products end to end — design, build, run, and improve them with a product mindset, treating fellow engineers as your customers and shaping interfaces that are genuinely easy to build with.
• Start from the developer's day: figure out where the real friction is, decide what would actually make their work easier, and measure whether people adopt it once it ships.
• Take ownership of a topic, plan the work, drive it to done, and keep stakeholders in the loop.
• Set the bar for how we build with AI — turn an interesting idea into tooling people can actually rely on, and bring the rest of the team along with you.
• Shape architecture and technology choices for our platform foundations (Kubernetes, CI/CD, IaC on AWS) and for the AI capabilities on top, and share your perspective in technical discussions.
• Keep the platform reliable, secure, observable, and cost-aware. You'll join the on-call rotation and help troubleshoot production incidents.

• Capture reusable patterns, templates, and blueprints so the whole organization moves faster.

   

Requirements:

• Senior-level experience (5+ years) building and operating infrastructure or platform products.
• Hands-on GenAI experience — you've built with LLM APIs, tool/function calling, retrieval, agents, or agent frameworks and put them into real workflows.
• Modern AI coding tools (e.g., Claude Code, Codex) are part of how you work day to day.
• Strong AWS fundamentals and a genuine appreciation for Infrastructure as Code and Pipeline as Code.
• A real feel for developer experience — you can look at a feature and tell whether it'll make a developer's life easier or just add another thing to learn, because you've lived that friction yourself.
• Strong communication and collaboration skills — you work well in a team, share your opinions clearly, and can move a topic forward with people across functions.
• Solid engineering fundamentals: testing, debugging, code quality, and getting things production-ready.
• Familiarity with SRE / DevOps principles and observability concepts (CloudWatch, Datadog, OpsGenie, or similar).
• Proficiency in at least one language, ideally Python, Go, or TypeScript.
• A bias for shipping — you're comfortable taking something ambiguous and turning it into a working solution with sensible scope.

We're looking for a 3D Artist for Roblox projects who can fully own the 3D side of a title.

You will be the only 3D artist on the project, responsible for environments, characters/creatures, props, rigging, animation, asset import, and optimization in Roblox Studio.

Code and UI design are handled internally — we need someone who can take a written specification and deliver the complete 3D side of the game.

Tech Stack:

• Blender — modeling, UVs, rigging, animation, baking
• Roblox Studio — MeshParts, SurfaceAppearance/PBR, MaterialVariants, terrain, lighting
• FBX → Roblox pipeline — skinned meshes, deform-only export, maximum 4 bone influences per vertex
• Substance Painter / Photoshop / Krita — textures and baking
• AI 3D and texture generation — Meshy, Hyper3D-Rodin, Hunyuan3D, and similar tools — required

What We're Looking For:

• 2+ years of professional 3D game development experience
• A portfolio demonstrating a stylized low-poly / cartoon art style
• Clean topology, sensible UVs, and the ability to maintain a consistent art style and defined color palette
• Experience baking procedural/toon materials into textures using Cycles/Eevee and building materials for Roblox
• Rigging and skinning experience:
  • bone-based rigs
  • squash & stretch
  • deformation without scaling bones
  • looped animations such as idle, jump, and reaction
• Strong understanding of performance budgets:
  • polygon count
  • texture size and quantity
  • draw calls
  • CollisionFidelity / RenderFidelity
  • assets must perform well on mobile devices
• Environment art experience:
  • building complete themed locations
  • terrain
  • islands/biomes
  • props and decoration
  • readable silhouettes and strong composition
• AI-first workflow — you use AI to generate base shapes and textures, then refine and finish them manually. Manually blocking out assets from scratch when AI can handle the initial work is considered unnecessary overhead.

• Nice to have:
  • published Roblox games
  • mobile F2P experience

Responsibilities:

• Own the entire 3D production of a title:
  • themed environment set
  • roster of creatures/characters and variations
  • props and decorative assets
• Create rigs and looped animations for creatures
• Export and import assets into Roblox Studio, including checking:
  • scale
  • orientation
  • materials
  • deformation
• Optimize and reuse assets through:
  • modular kits
  • shared texture atlases
  • color/material variations instead of creating new meshes
• Work from a written specification and deliver the result already assembled and tested in Roblox Studio, not just a collection of .blend files
• Work in short, fixed release cycles — the complete art pass for a title should fit within a single cycle, with the next title already in the pipeline

What You Won't Have to Do:

• UI design
• Icons, thumbnails, and marketing art — handled internally
• Scripting or gameplay programming

What We Offer:

• 💰 $2,000+
• 🌍 Fully remote
• 🎨 Full ownership of the visual side of your project, with no micromanagement
• 🤖 AI tools are paid for and expected to be used to their full potential
• 📈 Live projects with real players and real revenue

Hiring Process:

We use a paid technical test.

You'll create one asset based on a written specification:

• either a creature with a rig and looped animation
• or a small environment set

The final result must be imported and properly assembled in Roblox Studio.

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 Middle-level Software Engineer to work on the core query engine of a large-scale distributed data platform. You will develop features across query planning, optimization, and execution, contribute to performance-critical components, and help evolve the platform's ability to process massive analytical workloads across heterogeneous data sources.

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

RESPONSIBILITIES

• Develop and maintain features across the query engine — planning, optimization, execution, and data access layers.
• Write high-quality, performance-conscious code in Java and/or C++.
• Work with SQL semantics, query plans, and execution operators over large-scale distributed data.
• Integrate with columnar formats, open table formats, and connectivity drivers used across the platform.
• Contribute to CI/CD pipelines and automated testing — participate in build, test, and release workflows in Jenkins.
• Deploy and validate work in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker.
• Debug complex issues spanning query planning, distributed execution, memory management, and I/O.
• Collaborate closely with US-based engineering teams on design reviews, code reviews, and technical decisions.

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 solid OOP and software design fundamentals. Candidates comfortable with both are especially valued.
• SQL & Data: Strong SQL skills and solid understanding of relational and analytical data systems, including query execution concepts.
• Data processing systems experience: Hands-on experience with data processing systems — query engines, distributed databases, ETL/ELT frameworks, or analytical platforms.
• Engineering experience: 3+ years in backend/systems software engineering.
• CI/CD & DevOps basics: Practical experience with Jenkins pipelines and modern development workflows.
• Containers: Working knowledge of Docker and basic Kubernetes (running workloads, debugging pods, kubectl fluency).
• Cloud: Comfortable operating in at least one major cloud (GCP, AWS, or Azure).
• Version Control: Confident with Git / GitHub workflows.
• 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.

DESIRED SKILLS

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.
• Please note: We can consider only candidates currently residing in the EU, EEA, or the UK
