We operate across the UK, US, UAE, Hong Kong, Singapore, and Europe, giving founders a single point of access to banking, payments, and legal searvices that would otherwise take months to assemble.

The Role

We're looking for a Chief Operating Officer to run the day-to-day engine of BankStore: the operational backbone connecting our clients to banks, acquirers, payment providers, and incorporation partners across multiple jurisdictions. You'll own operational strategy, scale our partner network and onboarding processes, and turn a fast-moving fintech marketplace into a predictable, efficient, and compliant operation. You will report directly to the CEO, sit on the leadership team, and work closely with Legal, Compliance, Product, and Partnerships.

What You'll Do

• Manage and grow relationships with partner banks, acquirers, payment providers, and incorporation agents across the UK, US, UAE, Hong Kong, Singapore, and Europe.
• Design and monitor operational KPIs (onboarding time, approval rates, turnaround SLAs, partner performance) and drive continuous improvement.
• Partner with Legal and Compliance to ensure operational processes meet KYB/KYC/AML requirements across all jurisdictions of operation.
• Lead and scale operations, customer success, and partnerships teams as the company grows headcount.
• Own the operating budget and resource planning across departments, working closely with Finance.
• Drive process automation and tooling improvements in partnership with Product and Engineering to reduce manual work in onboarding and account management.
• Oversee vendor and partner contract performance, escalations, and renewal strategy in coordination with Legal.
• Represent operations in leadership planning: pricing, market expansion (new jurisdictions/currencies), and new product launches (e.g., Web3 payments, banking cards).
• Build contingency and risk-mitigation plans for partner outages, compliance holds, or banking relationship disruptions.

• Report operational performance and business metrics to the CEO and board.

   

What We're Looking For

• 8+ years of operations leadership experience, with at least 3+ years in a senior operating role (COO, VP Ops, Head of Ops) at a fintech, payments, or banking-as-a-service company.
• Proven track record scaling multi-jurisdictional operations involving banking partners, payment providers, or acquirers.
• Working knowledge of KYB/KYC/AML onboarding processes and how they intersect with operational workflows.
• Experience managing partner and vendor relationships with financial institutions.
• Strong analytical skills with a track record of building KPIs, dashboards, and SLAs that drive measurable operational improvement.
• Experience building and leading cross-functional teams (operations, customer success, partnerships) in a fast-growing startup environment.
• Comfortable operating with ambiguity, building processes from scratch, and iterating quickly.
• Excellent written and spoken English; additional languages are a plus.
• Strong stakeholder management skills, able to work closely with Legal, Compliance, Product, and Finance leaders.

Nice to Have

• Experience with Web3/crypto client operations or compliance considerations.
• Prior experience at a banking-as-a-service, embedded finance, or fintech marketplace company.
• Experience operating across the UK, US, UAE, Hong Kong, Singapore, or EU markets specifically.

An early-stage IT consultancy is looking for an experienced Power Platform developer to join our team delivering software solutions.

You'll act as a trusted technical partner to non-technical business stakeholders, turning their challenges into automated workflows, user-friendly interfaces, and well-modelled data stores.

This is a client-facing role, so we're looking for someone with strong communication and business analysis skills alongside solid technical ability.

You'll work closely with the solution architect to understand business needs and bring the solution to life.

If you enjoy solving real business problems and want to interact with the people who use your work, we'd love to meet you.

2. Contribute to overall solution architectures.
3. Develop and implement Power Automate flows, transforming complex business logic into efficient solutions.

5. Design and develop Canvas and Model-driven Power Apps to meet client needs.
6. Troubleshoot problems and provide support to existing solutions.

This is a client-facing role that solves problems that require real technical depth. So we're looking for someone who is deeply technical and has strong communication skills.

Technical skills

• Low-code development with Power Platform (Power Automate, Power Apps)
• Pro-code development with TypeScript/Node.js, C#, or similar languages
• Data modelling and database design
• Fluent in API integrations
• Comfortable working with unfamiliar technologies

Communication skills

• Upper-intermediate/advanced English
• Clear and concise communication
• Able to elicit requirements and manage expectations
• Able to express yourself well in writing
• Comfortable communicating using Loom videos

🔹 Hiring process

1. Intro interview
2. Tech interview
3. Final interview
4. Offer stage

🔹 What we offer

• Competitive compensation based on your skills & experience
• 18 days of paid time off + 11 local national holidays every year
• Independence and support to do your best work
• Sponsorship of professional certifications

• Work where you want, remotely

No office traps.

We don't offer things like football tables, catered meals in the office, and other "perks" designed to keep you at work for all of your waking hours.
