About Us 

We're hiring on behalf of our partner — a company that powers the operations behind regulated and high-risk industries. 

They give fast-moving businesses in these spaces the structure, compliance and talent they need to scale — without slowing down.

Some things don't show up in a report until it's too late. Our partner is looking for someone who spots them anyway.

About the Role

They're hiring an AML & Compliance Analyst with hands-on experience in KYC/AML operations within crypto, iGaming, or FX.

This isn't a purely strategic or audit-only role — you'll be in the day-to-day: reviewing customer files, checking transaction alerts, verifying due diligence, screening for sanctions and PEPs, and making judgment calls on what needs to be escalated. On top of that, you'll help build and refine the quality processes that make all of this faster and more accurate over time.

You'll work closely with Compliance, Operations, and Management, owning both the daily casework and the bigger-picture improvements. If you've operated in high-speed, high-volume environments before and know how to stay sharp when things move fast, keep reading.

What We're Looking For

This is a role for someone who's hungry to build, not just maintain. You'll get the most out of it if you:

• Come from crypto, iGaming, or FX and have real, hands-on experience with KYC and AML operations — not just theory
• Take high ownership by default — you don't wait to be told, you see what needs doing and do it
• Are proactive, spotting risks and gaps before they're flagged by someone else
• Thrive under pressure in fast-moving, high-volume environments with constant case queues and shifting priorities
• Have a genuine appetite to learn — regulations, red flags, and industry tactics evolve fast, and you want to stay ahead of them, not catch up
• Are adaptable, comfortable moving between casework, investigations, and process improvement without losing accuracy
• Want to build something real — a stronger AML function because you were in it

What You'll Own

• Handle day-to-day KYC/AML casework — review customer onboarding files, verify identity and source-of-funds documentation, and conduct ongoing due diligence in line with risk-based procedures.
• Monitor transactions & detect red flags — review alerts, transaction patterns, and customer activity to identify unusual or potentially suspicious behavior in real time.
• Screen for sanctions, PEPs, and adverse media — run and assess screening results, resolving true/false positives accurately and efficiently.
• Investigate & escalate — assess suspicious activity, document findings, and escalate cases (including SAR/STR-level decisions) in line with internal procedures and regulatory requirements.
• Build & improve quality controls — develop, implement, and maintain QA processes that keep casework accurate and consistent as volume grows.
• Identify risks before they escalate — conduct regular audits and reviews of internal processes and controls to catch gaps early.
• Strengthen AML processes — work with Compliance and Operations to refine controls, procedures, and reporting accuracy based on what you see in the day-to-day.
• Own compliance communications — monitor incoming compliance-related emails, flag what's urgent, and escalate to management without delay.
• Manage multiple priorities — juggle live casework, investigations, and QA projects simultaneously, without losing accuracy or organization.
• Stay ahead of change — continuously build your knowledge of AML/KYC regulations, risk indicators, and best practices specific to crypto, iGaming, or FX.

What You Bring

• 2+ years of hands-on experience in KYC/AML operations, transaction monitoring, or financial crime prevention — ideally within crypto, iGaming, or FX
• Practical, working knowledge of KYC procedures, customer due diligence, sanctions/PEP screening, and SAR/STR processes
• Solid understanding of AML regulations, risk-based approaches, and compliance best practices in fast-moving financial environments
• A sharp, analytical, investigative mindset — you notice inconsistencies and patterns others miss
• Comfort operating with high ownership and autonomy, proactively identifying what needs to happen next
• Strong organizational skills and the ability to prioritize under pressure and tight deadlines
• Exceptional attention to detail
• A genuine self-learner mindset — curious, adaptable, and always looking to sharpen your regulatory and technical edge
• Strong written and verbal communication skills, with the confidence to raise findings and escalate concerns clearly
• Bachelor's degree in Finance, Accounting, Business Administration, or related field (relevant industry experience weighed heavily)

What You'll Get

• Competitive salary aligned with your experience
• Comprehensive benefits package
• Continuous professional development in a space that never stops evolving
• A fast-paced, high-ownership environment where initiative is rewarded and compliance is treated as a competitive edge, not a formality
• Direct collaboration with Compliance, Operations, and Management, with real influence over how casework and controls evolve
• A role built for people who want to build, not just maintain

Think You Have the Eye for Risk?

If you come from crypto, iGaming, or FX and know your way around a KYC file as well as you know AML regulation — if you question procedures instead of just following them, and you're hungry to build something stronger — this is your next challenge.

Who We Are:

Compare The Carrier / CTC Stack is a U.S. focused company building marketing, sales, analytics, automation, and AI solutions that help businesses grow and optimize their operations.

We have an established business in the logistics industry and are actively expanding into new products, services, and verticals.

Position: Head of New Business Sales & GTM — U.S. Market

We’re looking for an experienced, hands-on Sales & GTM leader who can build and scale new revenue streams for CTC Stack.

This is not a role for someone who only manages an existing sales team or waits for a finished sales playbook. We need someone who can identify commercial opportunities, build pipeline, personally close B2B deals, manage a sales team, and turn successful sales approaches into repeatable growth systems.

Key Responsibilities:

• Build and scale new B2B revenue streams in the U.S. market.
• Develop and manage a qualified sales pipeline across CTC Stack products, services, and new verticals.
• Personally lead discovery calls, proposals, negotiations, and closing of strategic B2B deals.
• Build, manage, and improve the performance of SDR / BDR / Sales team members.
• Develop sales processes, qualification criteria, pipeline stages, KPIs, and sales playbooks.
• Work with the CEO and internal teams on ICP, positioning, offers, pricing, and GTM strategy.
• Turn market research and discovery insights into actionable sales opportunities.
• Test new sales approaches, messaging, verticals, and channels.
• Identify new partnerships and business development opportunities.
• Analyze lost deals, objections, market feedback, and conversion data to improve the sales process.
• Build structured forecasting and maintain strong CRM and pipeline discipline.
• Help turn successful commercial experiments into scalable revenue systems.

Key Qualifications:

• 3+ years of experience in B2B Sales, Business Development, GTM, or Revenue Growth.
• Strong experience selling to the U.S. market.
• Proven track record of personally closing B2B deals, not only generating meetings.
• Full-cycle sales experience: prospecting → discovery → proposal → negotiation → close.
• Experience managing and developing SDR / BDR / Sales teams.
• Proven experience growing revenue and building sales pipelines.
• Experience selling to business owners, founders, CEOs, or senior decision-makers.
• Strong consultative and solution-based sales skills.
• Ability to build sales processes in an environment where not everything is already structured.
• Strong commercial thinking and ability to identify new revenue opportunities.
• Fluent English.

Would be a Plus:

• Experience selling AI, automation, SaaS, CRM / RevOps, MarTech, or technology solutions.
• Experience with performance marketing, lead generation, high-ticket agency services.
• Experience selling custom software or business process automation.
• Experience launching new products or entering new verticals.
• Experience in logistics, healthcare, dental, or other U.S. service industries.

Who We’re Looking For:

We’re looking for someone who wants to build, not simply maintain.

You should be comfortable working with evolving products, testing new approaches, challenging offers when the market is not responding, and taking real ownership of commercial results.

You should be equally comfortable leading a team and personally closing important deals.

Success in this role will be measured by new revenue, qualified pipeline, closed clients, sales team performance, and the ability to build repeatable GTM and sales systems.

Please apply with your CV, examples of B2B deals you closed, measurable revenue or pipeline results, and your expected compensation!
