Hraymo is a product game development company creating slot games for the global market. We focus on building visually strong and engaging in-game experiences for players worldwide.

We are looking for a Senior 2D Designer who will create in-game visual elements for slot games: logos, pop-ups, symbols, frames, UI elements and other in-game graphics.

The role works within an established visual style and art direction.
This is not a marketing or promo design role — the focus is on in-game production design for slot games.

     Requirements:

• 2+ years of experience as a Game Graphic Designer / 2D Designer (must in slots or gaming);
• Strong portfolio with examples of in-game UI, slot elements, symbols, pop-ups or game logos;

• High attention to detail and visual quality;

• Intermediate English or higher.

   

• Soft Skills (important for this role)
• Proactive and initiative-driven approach;
• Ability to suggest improvements and visual solutions, not just execute tasks;
• Ownership of visual quality inside the game;
• Structured and responsible working style;

• Good communication and teamwork skills.

  
  Responsibilities:

• Create and adapt in-game visual assets for slot games: logos, symbols, UI panels, pop-ups, counters, frames, buttons and win indicators;
• Improve and refine existing in-game content (polishing, reskins, adaptations);
• Prepare and optimize graphic assets for developers and animators (layers, formats, export, naming);
• Adapt visuals to different themes and styles (seasonal versions, variations, reskins);
• Create supporting promotional materials related to the games (banners, simple promo visuals, marketing assets when required);
• Collaborate closely with Artists, Game Designers and Developers to ensure high-quality in-game implementation;
• Maintain visual consistency and quality across all game features and interfaces;

• Work with tasks and feedback using Jira and Miro.

  
  We offer:

• A competitive rate fixed in EUR with an annual review;
• Flexible time off to rest and recharge;
• Additional days off and public holidays observed by the company;
• Health-related time off when needed;
• Medical insurance coverage after the trial period;

Who are we searching for?

We're looking for a Head of Engineering who's already been the senior technical person at a small startup — writing code, making architecture calls, and keeping founders in the loop without being asked. 

You'll own engineering fully — the team, the delivery, the architecture, the quality bar, and the overall engineering state of the company. This is not a coordination role. You'll write production code daily on the hardest problems: AI agents, MCP infrastructure, forecasting systems, and financial analytics. You'll be the person who says what's doable, shapes scope, and decides how the team works.

The team is 4 engineers, 1 QA, and 1 Product Owner. The direction is set — we're looking for someone to run the room.

If that matches your experience, let's talk.

What are your responsibilities?

• Build and maintain the forecasting agent and financial analytics platform
• Develop MCPs and the agent orchestration layer
• Own dashboards, access controls, and reporting infrastructure
• Build the AI coding culture across the team — by example, not by policy
• Drive end-to-end engineering delivery: planning, estimation, and accountability
• Own technical architecture across the full stack and AI layer
• Negotiate and control scope — before it reaches the team
• Maintain code quality, CI/CD, automated testing, and deployments
• Run 1:1s, give feedback, and support engineer growth
• Lead hiring as the team scales
• Send engineering reports proactively — blockers, throughput, what changed, and why
• Translate technical constraints into business language for founders and non-technical stakeholders

What are the preferred requirements for the role?

• 5+ years of engineering experience, 2+ years as Tech Lead or Head of Engineering at a startup under 50 people — still writing code daily
• TypeScript / Node.js · React, ideally NestJS knowledge
• Shipped AI in production: LLM integration / RAG, agents, MCP — real users, not demos
• Daily AI tooling: Claude Code, Cursor, Augment, or equivalent 
• People leadership experience: 1:1s, feedback, hiring
• B2B SaaS experience, preferably in fintech or a data-heavy domain
• Clear and proactive communication with C-level executives
• C1 English

Good to have:

• Financial API integrations: QuickBooks, Xero, Stripe, or similar
• FP&A domain: P&L, forecasting, budget vs. actuals
• Side projects or open source built with AI tooling
• Experience with MCPs and agent orchestration

Reporting Structure: reporting to the CEO

Recruitment Process:

1. Recruiter interview 
2. Tech fit & live coding session with Fuel engineers 
3. System Design and Behavioural interview with Fractional CTO 
4. Culture fit interview with the CEO

Why work with us?

• You'll own engineering fully — not inherit someone else's decisions
• Work on real AI: production agents, MCP infrastructure, financial intelligence that SMBs actually depend on
• Small team, high trust — no politics, no layers, no meaningless meetings
• Competitive salary + equity 
• Freedom to define how engineering works — tooling, process, standards are yours to set
• Flexible schedule and async-friendly culture
• 18 days paid vacation per year + paid sick leave
• You'll see the impact of your work directly — in the product, in the team, and in the businesses we serve
