We are looking for a Junior Frontend Developer who already has real hands-on experience building complete, non-trivial web applications and wants to grow into a strong mid-level engineer.

• at least 6 months of hands-on experience building full-featured, production-like websites or web applications;
• strong knowledge of HTML, CSS, JavaScript;

The Role

You’ll build and maintain the backend services behind our automations. What sets this role apart is how you work: we expect you to ship fast and efficiently by driving AI coding tools rather than hand-writing everything. You frame the problem, point the model at the right inputs and context, own the plan, and run a rigorous final code review. The AI writes most of the code — you’re the engineer who makes sure it’s correct, fast, and production-ready.

We’re looking for someone genuinely strong with modern AI tooling — treating it as a core part of the workflow, not a side experiment — including a solid AI harness with strong automated code validation and verification built in.

Responsibilities

• Design, build, and maintain backend microservices for process automation
• Deliver features fast using AI coding agents: scope the task, prepare inputs/context, define the plan, and review the output critically
• Investigate and reverse-engineer the behaviour of private/third-party APIs
• Integrate automations across the platforms and keep them reliable in production
• Optimize systems for performance, scalability, and reliability

• Collaborate with the team on architecture and technical decisions.

   

Required Expertise

• Solid engineering judgment: able to read, review, and correct AI-generated code and catch subtle bugs
• Strong Node.js / TypeScript backend background for scalable, high-load systems
• Microservices design with high availability and fault tolerance
• Experience with time-series/PostgreSQL workloads (TimescaleDB)
• Event bus and message queue familiarity (Kafka, RabbitMQ, SQS)
• Cloud platform knowledge (AWS, GCP) and containerization (Docker, Kubernetes)
• Problem-solving mindset for high-traffic systems
• Strong, hands-on AI-assisted development skills — daily use of coding agents (Claude Code, Codex, etc.) to write and ship code efficiently

• A robust AI harness with strong code validation/verification, so AI-generated changes are automatically checked before they land.

   

Requirements

• 5+ years of backend engineering experience (Senior level)
• Node.js, TypeScript, JavaScript proficiency
• Proven experience shipping code with AI coding tools
• Ukrainian language: native speaker level
• Full-time, fully remote position

• Global candidates considered

   

Benefits

• 20 vacation days + 10 sick days
• Flexible schedule, fully remote
• Sports, psychology, and health insurance budgets
• Education and English course funding
• Team-building events
• Personal Development Plans

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.

Project Information:
The project focuses on building a complex, real-time, multi-component system with deep hardware integrations, strict scope control, and high reliability requirements.

Requirements
● 3+ years of experience as a Business Analyst in IT, with hands-on work on complex systems or integration-heavy projects across multiple domains.
● Strong understanding of the software development lifecycle, with a particular focus on system analysis and integration-driven solutions.
● Proven experience in eliciting and structuring requirements in technically complex environments (interviews, deep-dive sessions with engineers, document and specification analysis).
● Ability to quickly understand complex domains, hardware-related constraints, and evolving system behavior, and translate them into clear, structured requirements.
● Solid stakeholder management skills, including working with technical and non-technical stakeholders under time and responsibility constraints.
● Strong experience in defining and documenting functional and non-functional requirements, including:
— system flows;
— integration requirements;
— business rules and automation algorithms;
— simulation systems;
— constraints and assumptions.
● Experience working with multiple requirement formats: user stories, acceptance criteria, system specifications, sequence diagrams, BPMN/UML, state diagrams.
● Ability to decompose complex end-to-end system flows into clear, testable, and implementation-ready components.
● Confidence in change management: identifying impacts, managing dependencies, and maintaining system consistency when requirements evolve.
● Strong focus on scope control: ability to work strictly within the approved scope, clearly distinguish scope from assumptions, and prevent uncontrolled scope expansion.
● Strong collaboration skills with cross-functional teams: backend, system engineers, embedded/hardware-related teams, QA, and product/project management.
● Ability to reason about business value and risk when working with different solution options in responsibility-heavy and technically complex domains.
