• Working knowledge of cloud infrastructure primitives: Virtual Private Cloud (VPC), IP Address Management (IPAM), IAM, Observability, and Billing.
• Proven track record of independently navigating complex, legacy, or partially documented codebases, delivering meaningful contributions within the first 4–6 weeks.
• Rigorous written communication and documentation hygiene: writing thorough pull request descriptions, architecture decision records, clear READMEs, and structured handoff documentation.
• Time zone flexibility with sufficient working overlap during US Eastern Time (ET) business hours.

Nice to have:

• Hands-on experience with modern observability stacks: OpenTelemetry (OTEL), Grafana, Loki, and VictoriaMetrics.
• Exposure to configuration management platforms (particularly SaltStack).
• Experience with distributed task queues, event-driven architectures, and high-availability database replication.

Turn messy workflows into simple apps

Fully remote  ·  CET working hours  ·  Employment or freelance contract

A customer needs a better way to track requests, route approvals, or see what’s holding up a process. You’ll find out how the work gets done today, then use ELWIS, Softacus’s low-code platform, to build an app that makes it easier. You’ll take it from the first conversation to a solution people can use.

What you’ll work on

· Build customer apps. Configure data models, business rules, and workflows. Create the forms, pages, and dashboards people use to get their work done.

· Test and refine your solutions. Check that the app fits the way customers work, help them use it, and adapt it as their needs change.

· Show what’s possible. Build prototypes and demos, and work with developers when a solution needs custom code.

What you bring

You learn new tools by experimenting, ask good questions when requirements are unclear, and can break a messy process into rules and steps. You’re comfortable owning a solution from idea to delivery and bringing in teammates when needed.

Experience we especially value

· Web building and prototyping. Building web pages with WordPress or similar tools, or using vibe coding with MCP server to turn ideas into working prototypes with AI.

· Workflow automation. Connecting tools and automating tasks with n8n or similar platforms. Experience with VBA or robotic process automation (RPA) is also welcome.

· Process and system modeling. Mapping business processes using business process modeling (BPM) or describing how a system works with UML.

Experience with Power Apps, Retool, or another low-code platform is a plus. 

You can start without prior ELWIS or programming experience.

Own the affiliate programme of a fast-growing US sweepstakes casino.

Epic Play Holding is scaling fast across the US, Canada and other Tier-1 markets, and our affiliate programme is one of the main engines of that growth. We're looking for an Affiliate Manager to take it over: grow the partners we already have, bring in new traffic sources and make sure every partnership delivers quality traffic that pays off.

You'll have the tools, the product and the freedom to decide how the programme grows. This isn't partner support. You'll run the programme and own the results.

What you'll own

• Existing partners. Build strong relationships with current affiliates and find ways to grow their volume and revenue.
• New partners. Research new traffic sources, then attract and onboard affiliates across the US, Canada and other Tier-1 markets.
• Performance. Track traffic, volume, conversion, revenue and profitability for every partner, and spot drops before they become problems.
• Traffic quality. Catch and stop fraudulent, low-quality or non-compliant traffic, and act fast when a partner stops meeting expectations.
• Deal terms. Negotiate and manage commercial terms, mostly RevShare.
• Affilka. Use it every day for onboarding, tracking and performance analysis.
• Clear reporting. Keep partner reports and documentation accurate and up to date.
• Industry presence. Represent Epic Play at affiliate conferences and industry events and build your network.

You're a great fit if you have

• proven experience in affiliate management, ideally in iGaming;
• hands-on experience with Affilka (this is a must for the role);
• a solid understanding of affiliate traffic, partner performance and RevShare models;
• experience with conversion, revenue, profitability and ROI;
• experience spotting fraudulent or low-quality traffic;
• strong negotiation and communication skills;
• English at B2 level or higher and confidence working with international partners;
• readiness to travel internationally for conferences;
• an analytical mind and attention to detail;
• ownership and drive: you find new partners and ways to improve results without being asked.

You'll stand out with

• an existing network of US or Canadian affiliates;
• experience with Tier-1 traffic;
• experience with US casino or gambling products;
• a track record at affiliate conferences;
• deep knowledge of affiliate operations and traffic monetisation.

Why Epic Play

• Salary + bonuses. Market-level base, and bonuses tied to your results.
• Real ownership. You run the affiliate programme, not a small part of it.
• Direct impact. Your partnerships drive traffic growth and revenue you can see.
• Tier-1 partners. Work with international partners in the strongest markets.
• Conferences. Attend the major affiliate events and grow your network.
• Autonomy and growth. Freedom to make decisions and room to grow with the company.
• Fully remote. Work from wherever you do your best work.
