Jobs at Djinni

We're looking for an experienced Go Backend Developer to build a server-side slot game engine from scratch on a Go-based GDK. This is a 3-month freelance project with full ownership of the engine — from math model to RGS integration and certification readiness.

You'll be the game-logic authority on the project, working closely with a Game Designer, Mathematician, and Frontend Developer.

What you'll be doing

• Building the slot engine end-to-end: lifecycle interfaces (spin generation, keep-generate, history replay), win evaluation, and RGS integration contract
• Owning the game mathematics: RTP structure, reel strips, paylines / clusters / Megaways / avalanche, and probabilistic outcome modelling
• Implementing the full feature set: free spins, buy bonus, ante bet, max-win validation
• Externalizing all math configuration (reel sets, RTP, volatility, paytable) so Game Design and math can update values without code changes
• Running RTP simulation and validation harness; attaching simulation reports to each submission
• Driving builds through platform integration review and remediating findings until accepted
• Maintaining backend documentation: math/game-logic spec, config format, architecture records, README
• Actively using AI tools (Claude, ChatGPT, Gemini) to accelerate scaffolding, math modelling, and documentation — with reproducible, documented workflows

What we're looking for

• 3+ years of Go backend experience, layered service design, unit-testable game logic
• SDK lifecycle interfaces: spin, keep-generate, deterministic history replay
• Server-authoritative slot math: RTP, reel strips, paylines, Megaways, cascades, free spins, buy bonus
• All math in config — no hardcoded values; integer/fixed-point arithmetic only, no floating-point on monetary ops
• RNG exclusively via SDK-injected client
• Deterministic replay, idempotency, SDK compliance discipline, OWASP Top 10 awareness
• RTP simulation with reproducible reports; Go profiling, structured logging, clean SAST/DAST

Nice to have

• Production experience shipping slot or iGaming titles with server-authoritative math
• RGS or aggregator SDK integration experience
• Certification experience (GLI-19 or equivalent)
• Mathematics or probability background for RTP modelling
• gRPC alongside HTTP transport
• CI/CD pipeline experience
• TypeScript sufficient to read client-side SDK and reproduce frontend defects
• PixiJS / Spine familiarity

What we offer

• Strong mid-senior team — you'll work with experienced engineers, not learn on the job alone
• Real architectural influence — this is a greenfield engine, your decisions shape the product
• Flexible schedule — we care about results, not hours logged
• No micromanagement — you own your scope end-to-end and are trusted to deliver

About you

You’re an expert software engineer with outstanding attention to UI/UX. When you need to ship backend features, you don’t need someone else to step in. We don’t expect a backend ninja, but simple CRUD shouldn’t intimidate you.

The definition of "expert" varies, so let’s narrow ours down:

• Elite communication: You set expectations accurately and you live up to them. No surprises. Our team works in Russian & English*
• Deep resilience: Bugs, crises, or tough discussions - you have a massive buffer before stress impacts your output. You don't crack under pressure.
• No ego: We are here to win, not to manage insecurities.
• Product mastery: You understand the engineering principles behind the greatest software products ever made. Be ready to discuss under the hood of your tools.

Engineering culture

• Optional code reviews: We trust you. Merge when you're ready. If you want a second pair of eyes, just ask.
• Radical autonomy: We don’t second-guess your decisions. You own the call.
• High-bandwidth collaboration: We talk constantly, so everyone has context without needing formal gates to catch up.
• Direct feedback: When we do review code, comments are blunt, concise, and respectful.
• Ruthless efficiency: We aggressively adopt any tool (AI included) that increases leverage and speed.
• Limited test coverage on FE: We supplement that with good architecture and top talent.
   

About the role

• This is the second seat on our mobile team. Today, one engineer owns our entire mobile codebase end-to-end: live on iOS & Android, paying customers, real subscription revenue.
• You'll partner closely with our founder, our PM, our backend engineer, and our designer. 
• AI is woven through the product itself, not just our build process: features that take real action on the user's behalf, conversational interfaces, LLM-driven recommendations. That means staying close to the models, prototyping fast, and being comfortable shipping into surfaces where the underlying capability is still moving.
• We care deeply about craft, the details that make the product feel polished and trustworthy on a 60fps thread. But we ship fast and learn in the open. We'd rather get a paywall variant in front of users this week than perfect it for a month.
• This role is fully remote with morning Chicago overlap (10am–2pm CT) for standups and demos.

Benefits

1. You’ll learn a lot: Steep learning happens outside of your comfort zone. If you’re eager to learn, it means you’re hungry for uncertainty and discomfort. We only hire people like that. We promise to push you out of your comfort zone and give you access to extract as much knowledge as possible from the environment we’ve created.
2. You’ll get rich: A startup environment often feels like eating glass. And if someone decides to eat glass with us, they deserve their slice of the pie. That’s why besides equity, we also have profit share for core team members as part of our compensation package.
3. Earning your first $1M means enduring $1M worth of pain, but if you’re up for it, we’re here for you. We don’t hire people that aren’t obsessive, so the main question shifts from if to when .
4. You’ll own your slice of the pie: You’ve probably heard stories from corporates about "extreme ownership" that turned out to be capped by a manager. We don’t have managers, you are the one responsible. You’ll have the entire team’s trust.
5. The only limit is business reality: we want to earn money, not just be around.
6. You’ll have our back: Our recruitment philosophy is similar to the Navy Seal’s one. We have a culture where entrepreneurs can thrive. We know exactly what “tough” really means, so we watch each other's backs.

It should feel like a steal

You’ll join a team of experienced builders to create the next massive success. In your first six months, you’ll learn more - while getting paid - than you have in the last few years combined. You will be trusted, respected, and heard. If it doesn’t feel like a steal for you, it’s probably not be what you’re looking for at the moment.

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.
