We are looking for a senior technical consultant with hands-on experience in mobile traffic infrastructure, backend routing, attribution, Keitaro, GEO segmentation, and anti-abuse systems.

Our current architecture is:

iOS App → AWS ECS / ALB → API → Keitaro

We need an expert to review the existing setup and help us design a reliable production-ready traffic routing and filtering architecture.

The main goal is to understand which traffic signals are realistically available within this stack, which of them are worth using, and how to structure the decision logic between the mobile app, backend, AWS infrastructure, and Keitaro.

Areas we would like to review include:

— IPv4 / IPv6
— GEO location and country-level routing
— ISP / ASN data
— VPN / proxy detection
— User-Agent
— Referrer data
— DNS-related signals
— suspicious or known-abuse IP databases
— request-rate limits and anti-bot / anti-abuse rules
— traffic attribution between different apps, sources, GEOs, and offers
— Keitaro tracking parameters, click IDs, subIDs, and postbacks
— offer routing, weighted distribution, caps, and fallback logic

We would also like an assessment of more advanced identification signals, including:

— device fingerprinting
— device-level signals available on iOS
— battery-related or environment signals
— third-party detection APIs / SDKs

We want to understand which of these signals are technically available on iOS, which require changes in the mobile application, what privacy or reliability limitations they have, and whether the additional complexity is justified.

Expected deliverables

We are initially looking for a technical consultation and architecture review, not immediate full-scale development.

We expect the specialist to provide:

— review of our current architecture;
— recommended traffic routing and filtering logic;
— recommended data sources, APIs, or services;
— assessment of accuracy and false-positive risks;
— expected infrastructure and third-party API costs;
— recommendations for Keitaro integration and attribution;
— QA / staging approach for testing the complete flow;
— clear implementation plan for our existing AWS + Keitaro infrastructure.

Preferred experience

Strong practical experience with several of the following is important:

— iOS mobile traffic infrastructure
— backend traffic routing
— AWS ECS / ALB
— Keitaro or similar tracking platforms
— mobile attribution
— server-to-server postbacks
— GEO / ASN / VPN / proxy detection
— anti-bot and anti-abuse systems
— affiliate traffic infrastructure
— high-volume traffic systems

Experience with real production mobile affiliate projects is highly preferred.

Please include a short description of similar systems you have worked with and explain what parts of this stack you personally designed or implemented.

We are open to starting with a paid 1–2 hour technical consultation.

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.

Overview 

We are supporting an international technology manufacturer with an established global IT team and infrastructure projects spanning the UK, North America, and Asia.
 

The client has recently secured strategic investment and entered a new phase of growth, creating strong long-term momentum across engineering and technology initiatives.
 

This role will provide oversight and practical governance for four ongoing infrastructure projects with a combined budget of approximately £1.1 million. The CEO has backed short-term support to help get delivery back on track.
 

The ideal candidate will have proven experience managing complex IT infrastructure projects across multiple sites, along with the technical understanding needed to engage confidently with specialists and challenge delivery assumptions.

About the Environment
Global Network and Server Infrastructure Projects (working title). Reliable timelines have been difficult to establish across the portfolio. The immediate need is to understand the actual delivery position, clarify ownership and dependencies, and establish credible plans.
 

The four projects are:
— Global network segmentation using Aruba ClearPass: An initial site implementation has been completed; the remaining international sites are outstanding.
— Global enterprise backup: Implementation of a new global backup system using Veeam and HP StoreOnce.
— Server refresh: A complete server refresh at a North American site.
— Legacy infrastructure migration: Migration of infrastructure services from Windows 2000 to Windows Server 2022 at an Asian site.

Early priorities are to establish each project’s status, risks, dependencies, owners and next steps; develop realistic plans with the teams; and introduce proportionate governance and reporting that gives the senior IT lead visibility of progress and decisions required.
These are intended priorities rather than agreed deliverables. Detailed scope, milestones and completion dates will be established once the project position has been assessed.

Existing Team Structure
The Programme Manager is expected to report to the client’s senior IT lead and work with the established global IT team, technical project teams, suppliers and local site stakeholders.

The detailed team structure, supplier involvement, reporting lines and decision-making arrangements are to be confirmed. The role requires the ability to operate with minimal supervision.
 

Must-Have Experience & Skills

Technical:
— Demonstrable experience managing complex IT infrastructure projects across

multiple sites.

Business & Delivery
— Experience introducing practical governance and clear progress reporting.
— Ability to identify risks, blockers and decisions, and escalate issues promptly.
— Strong written and verbal communication with technical teams and senior stakeholders.
— Self-sufficient and proactive; able to establish priorities with limited oversight.
— Comfortable working with evolving priorities and partially defined requirements.

Nice-to-Have Skills
— Network segmentation experience.
— Enterprise backup implementation experience.

— Clear communication of progress, risks and decisions.
— Effective collaboration with experienced technical teams and stakeholders across locations.
— Comfortable working independently and collaboratively.
— Able to shape workable responses to delivery blockers with limited oversight.

Responsibilities 
— Oversee the four projects and establish their current delivery status.
— Work with technical teams to clarify outstanding work, ownership and realistic timelines.
— Coordinate plans, dependencies and decisions across locations.
— Identify delivery risks and blockers and ensure they receive timely attention.
— Introduce practical governance and clear progress reporting.
— Give the senior IT lead visibility of progress, priorities and decisions required.
— Escalate delivery issues promptly and help shape workable responses.
— Operate independently while maintaining effective relationships with the global IT

team.
 

Assessment Process
1. CV Review. 
2. Technical interview (45 mins) – Technical screening to understand experience. 
3. Final informal interview with client stakeholders (30 mins) – Cultural fit, collaboration instincts, MVP mindset.

• Comfortable working in agile environments and taking initiative to solve problems.

Nice to Have:

• Experience with SFTP, SharePoint, or other enterprise integrations.
• Experience integrating with PowerPoint, Excel, or working with Power Queries.
• AI is used as part of the daily engineering routine — e.g., for troubleshooting and root-cause analysis — so hands-on experience with AI tools is a plus, and any background in AI integration is welcome, though not required.
• Knowledge of monitoring and logging tools within AWS.
• Previous experience in the fintech or asset management domain.
• Awareness of security practices for serverless apps (IAM roles, API authorization, secret management).

Stages of Interview:

• Interview with a Recruiter (45 minutes).
• Internal technical interview (1,5 hour).
• Interview with the client (1 hour).

Gensoft is looking for a Senior Go Engineer for a long-term client project: a Go service that orchestrates cryptographic signing between distributed participants, including mobile clients. The service is already running in early production, and we need an engineer who can take ownership of it and bring it to a robust production baseline.

ABOUT THE PROJECT

- A Go-based service that orchestrates cryptographic signing between distributed participants, including mobile clients. It integrates with multi-party signing libraries, supports encrypted storage and must recover safely from interrupted sessions and other failures.
- The service works and is at an early production stage. There are open pull requests, observability improvements and concurrency issues to address. Handover from the previous team may be limited.
- You will work with backend and mobile engineers, QA and cryptography specialists. Collaboration across UK and North American working hours is important.
- Stack: Go, Linux, Docker, shared SDKs and bindings for mobile and web platforms.
- Initial focus: understand the codebase, resolve reliability and security issues, improve tests and support releases. Later work may include new product features and longer-term cryptography roadmap items.

RESPONSIBILITIES

Core service engineering
- Maintain and improve the Go service: signing orchestration, communication between participants, encrypted storage and failure recovery.
- Investigate concurrency, timeouts, interrupted sessions, network failures and service restarts; review open pull requests and fix race conditions.
- Improve logging and observability, assess the existing implementation critically and make careful, maintainable changes.
- Contribute to new features and future cryptography work as the roadmap develops.

Cryptography, SDKs and cross-platform integration
- Maintain integrations with multi-party / threshold signing libraries, working with cryptography specialists where changes affect protocol security.
- Contribute to shared SDKs and bindings connecting Go with mobile and web clients.
- Work with backend and mobile engineers to preserve API compatibility and consistent behaviour across releases.

Quality, testing and operations
- Improve automated tests for signing correctness, failure recovery and interoperability between server and mobile components.
- Support Linux and Docker deployments, dependency upgrades, monitoring, release processes and operational documentation.
- Investigate production issues and occasionally help with customer setup or logging problems.

Ownership and technical judgement
- Take primary ownership of a security-critical codebase and independently establish a robust production baseline.
- Assess technical risks and trade-offs, explain decisions clearly and make incremental changes with sound security judgement.
- Collaborate pragmatically with backend, mobile, QA and cryptography specialists across time zones.

REQUIREMENTS

- Strong hands-on production experience with Go: goroutines, channels, context cancellation, race detection, profiling and resource management.
- Experience owning production services, diagnosing complex failures and delivering well-tested fixes.
- Distributed systems knowledge: asynchronous messaging, retries, idempotency, state management and partial failures.
- Practical security engineering: authentication, encrypted storage, sensitive data handling and safe logging.
- Applied cryptography concepts: digital signatures, hashing, key management and signature verification.
- Automated testing, CI/CD, Linux, containers and production observability.
- Ability to understand an established codebase, make careful incremental changes and explain technical decisions clearly.
- English at Upper-Intermediate level or higher.

NICE TO HAVE

- SDK development for JavaScript/TypeScript or mobile platforms (Swift, Kotlin), including asynchronous APIs, packaging and Go interoperability.
- Cross-platform mobile development, secure storage or native modules.
- MPC or threshold signatures, distributed key generation (DKG).
- Blockchain transaction signing.
- Confidential computing and hardware-based attestation.
- Messaging protocols, Protocol Buffers, Prometheus or OpenTelemetry; interest in emerging signature schemes.

WHO WILL BE A GOOD FIT

- Experience with digital asset infrastructure or MPC is valuable, but the priority is strong production Go and sound security judgement.
- Relevant experience in other security-critical distributed systems also counts.
- You do not need experience with every "nice to have" technology. Evidence of ownership, careful delivery and learning across platform boundaries matters more.
- You are independent and can get up to speed on an existing repository with limited handover.
- You pay attention to correctness and take a careful approach to critical systems.
- You can assess implementation choices critically and explain risks and trade-offs clearly.
- You are pragmatic and collaborative with backend, mobile and cryptography specialists.
- You are comfortable diagnosing production failures and improving reliability through tested changes.
- You communicate effectively in a remote setup and are flexible to overlap with UK and North American working hours.

WHAT WE OFFER

- Fully remote work.
- Real ownership of the codebase and influence on technical decisions.
- Work alongside strong backend and mobile engineers, QA and cryptography specialists.
