Jobs at Djinni

About the Role

We’re looking for a Senior Software Engineer to join a newly forming team that will own one of the most specialised and business-critical domains in our technology landscape — Game Engine.

This role sits at the intersection of engineering, game mathematics, platform, and compliance. You’ll work on the tools, frameworks, and services that enable our mathematicians and game teams to build, validate, run, and monitor game logic in production.

This position is about deep ownership of a very specific technical domain: game engines, mathematical packages, simulation data, RTP monitoring, round details, and integrations with games developed both internally and by external studios.

You’ll be part of a small, experienced team with a high level of responsibility. The impact of this work is direct: incorrect game logic, missing round details, or inaccurate RTP monitoring can affect game delivery timelines, business performance, and regulatory readiness.

If you enjoy working close to complex domain logic, reviewing technical implementations, understanding how games work under the hood, and owning systems where precision matters — this role will feel like home.

Key Responsibilities

• Own, maintain, and evolve Playson’s Game Engine domain
• Work on internal frameworks and libraries used by mathematicians to implement game logic and mathematical packages.
• Review and validate code written by mathematicians, ensuring quality, correctness, maintainability, and proper usage of internal frameworks.
• Contribute to the development and support of game engines used to run mathematical logic within our platform.
• Support integrations with external game studios by helping build wrappers and bridges between third-party game implementations and Playson’s platform.
• Work with data structures and protocols that connect game logic with frontend and backend systems.
• Contribute to RTP monitoring processes, including validation of production transaction data against simulation data and expected mathematical behaviour.
• Support and evolve tools used for mathematical review, simulations, data files, monitoring, and alerting.
• Implement and maintain round details logic required for regulated markets, ensuring that detailed game round information can be correctly provided to partners and regulators.
• Collaborate closely with mathematicians, backend engineers, platform teams, compliance stakeholders, and product representatives.
• Participate in code reviews and technical discussions to ensure a high engineering standard across the Game Engine domain.
• Investigate issues related to game logic, mathematical validation, monitoring, and engine behaviour.
• Participate in minimal on-call responsibilities related to the systems owned by the team, mainly around monitoring, alerts, and domain-specific incidents.
• Take ownership of a highly specialised area where quality, accuracy, and attention to detail are essential.

Requirements

• Strong software engineering experience, ideally in backend, game engine, gaming, gambling, betting, or simulation-heavy environments.
• Solid experience with Node.js/TypeScript, or strong expertise in another OOP language such as C++, Java, C#, Go, or Python.
• Good understanding of software architecture, code quality, testing, debugging, and maintainability.
• Experience reviewing complex code and providing clear technical feedback.
• Ability to understand domain-specific logic and work with technical systems where business rules, mathematics, and engineering are closely connected.
• Strong problem-solving skills and ability to work with complex, non-standard technical challenges.
• Experience working with production systems where reliability, accuracy, and correctness are critical.
• Understanding of backend systems, APIs, data flows, and service-to-service communication.
• Ability to collaborate closely with non-engineering technical experts, especially mathematicians or domain specialists.
• Strong ownership mindset and willingness to become a key expert in a narrow but highly important technical domain.
• Product-oriented thinking, with an understanding that games are the core product and engineering decisions directly affect delivery, quality, and compliance.
• English communication skills sufficient for working in an international environment.

Nice to Have

• Experience in iGaming, gambling, betting, game development, or casino games.
• Experience working with game engines, mathematical engines, simulation tools, or game logic frameworks.
• Background in C++ or experience working with legacy C++ systems.
• Experience with mathematical models, probability-based systems, simulations, random generators, or RTP-related logic.
• Understanding of regulated markets and compliance requirements in iGaming.
• Experience with ClickHouse or other analytical/columnar databases.
• Experience with monitoring, alerting, and production diagnostics.
• Experience with AI-assisted code review or automated validation tools.
• Knowledge of microservices architecture and distributed systems.
• Familiarity with Kafka, gRPC, Kubernetes, or AWS.
• Experience integrating third-party games, external studio products, or wrapper-based solutions.
• Ukrainian language skills would be a plus.

🚀 We're Hiring: CRO Specialist / Funnel Manager

We're a high-volume performance marketing company — and we're looking for someone who is obsessed with conversion data and knows how to act on it fast.

This isn't a "build pretty pages" role. We need a ruthless optimizer. Someone who lives inside tracker dashboards, runs aggressive A/B tests, and knows exactly when to cut a losing funnel and scale a winner.

What you'll own:
→ Daily management, setup, and optimization of landing pages, offers, and traffic flows inside Keitaro (or equivalent trackers like Voluum / Binom)
→ Formulate hypotheses, launch split tests (headlines, layout, CTA, angles), and decisively cut losers while scaling winners
→ Work directly with media buyers — align funnel adjustments with incoming traffic sources, angles, and target audiences
→ Feed performance data and market trends back to copywriters and designers to brief high-converting creative assets
→ Monitor core KPIs (CTR, Conversion Rate, ROI, CPA) and translate raw data into strategic creative briefs

You're the right fit if you have:
✅ Hands-on experience with Keitaro (highly preferred) or equivalent self-hosted/cloud affiliate trackers — redirect rules, lander protection, and postbacks are second nature to you
✅ A background in direct-response marketing, affiliate marketing, or high-volume media buying (brand marketers or corporate UX designers — this role is not for you)
✅ True data literacy — you can open a tracker dashboard or spreadsheet, spot statistically significant trends instantly, and make decisions without hand-holding

Bonus points if you have:
⭐ Basic front-end skills (HTML / CSS / JS) to make quick landing page tweaks without waiting on a developer
⭐ Experience with spy tools (Adspy, Anstrex, or similar) to track competitor funnel trends

Comp: Base salary + performance-based commission

If you've diagnosed a sudden campaign drop, rebuilt a funnel from scratch, or turned a losing angle into a winner with data — we want to talk.
