Jobs at Djinni

Requirements:

• Strong backend development experience with C++ (the bulk of the backend is built on a custom in-house framework)
• Hands-on experience with AWS, particularly S3
• Proficiency with Protobuf
• Experience deploying and operating services on Kubernetes, including performance-driven traffic routing to pods
• Performance engineering skills — hash-based routing, SSD-based caching, and memory-mapped files
• Solid systems / low-level fundamentals (there is no off-the-shelf framework to rely on — much of the stack is custom)
• Ability to work highly autonomously and drive work forward with minimal supervision
• Strong communication skills and experience working in distributed teams (Europe/Ukraine time zone; ~1–2 hours of daily overlap with a US-based team)
• Hands-on experience with AI-assisted development tools — e.g. Claude Code and Codex — including AI skills, plugins, and MCP (Model Context Protocol), with a clear understanding of how to boost personal productivity and code quality using AI tooling

Nice-to-Have:

• Familiarity with OpenTelemetry / observability tooling
• Understanding of LevelDB SSTable concepts and sorted, time-keyed data structures
• Familiarity with Python (used only for a small metadata/auth service)
• Basic DevOps skills

Key Responsibilities:

• Optimize the performance of the C++ data-streaming backend — efficient delivery of large recorded datasets to the browser
• Work on infrastructure-level optimizations: traffic routing to Kubernetes pods, hash-based routing, SSD-based caching, and memory-mapped files
• Operate within a custom data-handling stack — a C++ framework, a custom HTTP server, and a proprietary data format built on top of LevelDB SSTables and Protobuf
• Take ownership of performance work end-to-end, proactively identifying bottlenecks and driving solutions independently
• Collaborate with a primarily US-based team with ~1–2 hours of daily overlap, while working largely independently
• Participate in code reviews and design discussions

About the Project:

You'll join the engineering team of a leading technology company building autonomous mobility and robotics systems. The team develops an internal data visualization platform — a "video and data player" that renders 3D scenes, lidar, and audio recorded by autonomous vehicles. This role sits on the performance work stream: the backend reads on-vehicle data stored in S3, deserializes it from a custom, time-keyed format, and streams it to the browser. The data-transfer service is implemented in C++, and most of the platform's performance gains are expected to come from the backend.

This is a long-term engagement for a strong systems engineer who enjoys low-level performance work and is comfortable ramping on a heavily custom stack with high ownership and minimal supervision.

• Generate and integrate AI-generated backgrounds and characters into final creatives
• Create dynamic motion graphics with strong visual impact and high CTR focus

Requirements

• Mandatory experience in iGaming / Gambling niche
• Strong understanding of casino visual style and promo mechanics
• Experience creating high-converting advertising creatives
• Strong skills in Adobe Photoshop, Adobe Illustrator, Adobe After Effects, Premiere Pro (or analogues)

• Ability to create not just “beautiful visuals”, but creatives that attract attention and drive clicks
• Experience working with AI tools for image/background generation is a strong plus
• Ability to work fast without losing quality

Important Style Expectations

We are looking for someone who can create visuals that feel premium, dynamic, and aggressive in a good way.

Expected style includes:

• powerful text animations
• neon glow
• cinematic smoke
• sparks and particles

Portfolio

Portfolio with gambling/iGaming cases is mandatory. Applications without relevant examples (banners, videos, promo creatives) will not be considered.

Conditions

• Payment per creative or per creative pack
• Long-term collaboration opportunity
• Stable task flow for strong performers
