We are seeking a commercially driven and highly technical Chief Technology Officer (CTO) to lead the evolution of a fast-growing iGaming and fintech ecosystem operating across multiple brands and regulated markets. This role is particularly suited to senior technology leaders coming from large-scale iGaming operators, platform providers, or game studios, who are looking to transition from managing a function to owning an entire technology ecosystem end-to-end.

Role Overview

This is a hands-on, high-impact role in a fast-moving environment where technology is central to commercial success, combining end-to-end ownership of engineering delivery with the strategic orchestration of a complex third-party platform ecosystem.

You will also lead the design and development of new products from scratch, combining internal engineering capabilities with third-party platforms to accelerate time-to-market while maintaining long-term control over core systems.

You will define and execute the company’s technology strategy across iGaming, trading, and fintech verticals—ensuring scalability, performance, regulatory compliance, and strong alignment with commercial objectives.

Key Responsibilities

• Drive engineering velocity, reliability, and accountability 

Product Build & Platform Ownership

• Define what is built in-house vs integrated via third-party platforms 
• Ensure scalable, future-proof foundations for all new products 
• Balance speed (via vendors) with long-term ownership (via internal systems)

Vendor & Platform Ecosystem

• Own the vendor landscape, including gaming providers, aggregators, payment systems, trading platforms, CRM, and KYC/AML tools 
• Evaluate, select, and negotiate vendors based on performance, scalability, and cost efficiency 
• Optimize build vs buy decisions to balance speed, control, and margin 

Platform Integration & Ecosystem Delivery

• Own the integration and delivery of all platform components into a unified ecosystem 
• Ensure seamless interoperability between internal systems and third-party platforms 
• Drive consistency, reliability, and performance across all integrations 
• Partner with product and commercial teams to align platform capabilities with business goals 
• Ensure a seamless user experience across brands, products, and markets 

Security, Compliance & Risk

• Own system security, infrastructure resilience, and data integrity 
• Ensure compliance across regulated markets (iGaming, CFDs, brokerage) 
• Manage operational and vendor-related risk 

Data & Performance

• Establish scalable data pipelines and real-time reporting infrastructure 
• Enable data-driven decision-making across trading, gaming, and marketing 
• Ensure tracking accuracy and performance visibility across all systems 

Team & Leadership

• Build, scale, and lead a high-performing engineering organization across backend, platform, DevOps, data, and integrations
• Define team structure, hiring strategy, and leadership layer as the organization scales
• Foster a high-performance engineering culture focused on ownership, quality, and delivery
• Act as a key member of the executive leadership team, contributing to overall business strategy

Key Requirements

Environment

• Multi-brand operator spanning multiple fintech verticals
• Hybrid ecosystem of third-party platforms and in-house services  
• High-volume, real-time systems across trading, gaming, and payments 
• Scaling organization with significant growth ambitions
• Complex integration landscape across PAM, aggregators, trading platforms, and payment systems

Why This Role

• Opportunity to move from functional ownership to full platform ownership

SKELAR is a venture builder that builds international IT product companies according to the rules of the venture capital world. Together with our co-founders, we assemble strong teams to launch tech businesses and win in global markets.

We are currently looking for a Infrastructure Engineer.

We are Leaply, an ecosystem of digital and physical products designed to help people build healthy habits and improve their quality of life. We operate in global markets - the US, Tier 1, Europe, and beyond.

In June 2024, we launched an app focused on habit-building, using a subscription-based monetization model and a performance-first marketing approach (Meta, Google, TikTok). Within the first two months, we achieved positive unit economics and are now on track to grow 10x by the end of the year.

Our team is building its third business together, with successful exits behind us and a deep understanding of our niche and target audience. We move fast, communicate openly, and set ambitious goals.

What you’ll do:

— Become the first hire in a new Platform team and build the infrastructure function from scratch - from strategy to execution, with full ownership and impact across the business;

— Transform infrastructure that has grown alongside the product into a mature, well-structured platform — with clear service maps, dependencies, and ownership areas;

— Take Terraform and Kubernetes to the next level of maturity: modular IaC architecture, standardized deployments, autoscaling — ensuring every release is predictable and reliable;

— Build a full observability system: metrics, logs, traces, alerting — so the team can proactively monitor system health instead of reacting after issues occur;

— Strengthen security practices: access management, secrets handling, protection from external threats — and make security an integral part of the engineering culture;

— Optimize data infrastructure — ensuring stable and efficient pipelines for analytics and business decision-making;

— Create platform templates for new services — so product teams can focus on features instead of infrastructure;

— Work across three core business domains — Product, Growth/Marketing, and Payments — building solutions that scale the entire business, not just individual teams.

This role is for you if...

Must-have

— 3+ years of commercial experience in Infrastructure / DevOps;

— Strong experience with Kubernetes + Helm (clusters, deployments, autoscaling, health checks);

— GCP — projects, networking, services, access management;
— Terraform — infrastructure as code, modules, state management;

— CI/CD — building and maintaining pipelines;

— Observability — monitoring, logging, alerting (Prometheus/Grafana or similar);

— Security — access control, secrets management, protection from external threats;

— Ability to write production-level code — not just scripts (Bash/Python), but also capable of contributing to backend (Node.js/TypeScript) to solve engineering challenges;

— Ownership mindset — proactively identifying risks, driving solutions, and thinking in terms of business impact;

— Actively using AI tools in your workflow to move faster and think broader.

Nice-to-have

— Experience with data tooling — building and maintaining data pipelines;

— FinOps — infrastructure cost optimization, budgeting, cost monitoring.

SKELAR is an environment for self-realization of people who are able to create successful companies. We call such companies the next big everything. We believe in their power and scale.

To do this, we have created all the opportunities within our venture builder:

— 8 SKELAR Platform teams that help businesses close any issues: from recruiting and communications to finance and legal issues;

— A community of founders who have already launched more than one business and can share practical experience;

— Internal clubs by professional areas: marketing, development, finance, recruiting, brand ambassadorship;

— Trainings, courses, attending conferences;

— Health insurance.
