Your Contribution to Our Growth
We are looking for a technical, detail-oriented API Integration Specialist to help connect Aquanow's platform with banks, payment processors, custodians, and digital asset providers around the world.
In this role, you'll serve as the primary technical point of contact during partner integrations. You'll work directly with external technical teams to understand their APIs, obtain sandbox access and credentials, review documentation, test endpoints using tools like Postman, and determine how their systems integrate with Aquanow's platform. You'll document technical requirements, define data mappings, identify implementation considerations, and work closely with engineering to ensure integrations are delivered successfully.
Rather than building production software, you'll own the technical discovery, validation, and coordination required to bring each integration to life. Every integration is different, so you'll play a key role in solving technical challenges, coordinating with internal and external stakeholders, and helping automate financial workflows such as account balances, deposits, withdrawals, and treasury operations.
This is a full-time, permanent, hybrid position based in either Dubai or Downtown Toronto. Candidates located in Dubai should be comfortable participating in evening stand-up meetings with our North American engineering team several times per week.
What You'll Do
- Engage directly with clients, client banks, financial institutions, payment processors and crypto partners to gather, clarify and document technical and operational requirements.
- Review, evaluate and interpret thirdparty API specifications and banking/crypto interface documentation (OpenAPI/Swagger, vendor docs, JSON).
- Produce detailed data mappings and transformation specifications (field-level mappings, types, validation rules) between our API models and bank/FI, payment processor, and crypto/custody/wallet schemas.
- Implement adapter rules and middleware configurations (mapping tables, transformation scripts, routing logic) in integration platforms or API gateways; maintain reusable adapter libraries and templates.
- Translate client requirements into engineering-ready artifacts: OpenAPI specs, sequence diagrams, acceptance criteria, user stories, and change requests; prioritize and hand off work to engineering and integration teams.
- Design integration architectures and API contracts, including authentication/authorization patterns (OAuth2, JWT, mTLS, client certs), error handling, idempotency, retry/backoff strategies and rate limits.
- Create and maintain integration runbooks, sample code/SDKs, Postman collections, test harnesses, and sandbox environments for partner onboarding and testing.
- Define and execute test plans and acceptance testing with partners: unit, integration, regression, security and performance testing; run partner UATs, capture defects, and coordinate remediation with engineering.
- Coordinate connectivity and security setup with partners and internal TechOps (IP whitelisting, VPNs, TLS/mTLS cert exchange).
- Monitor and validate production integrations, investigate incidents, perform root cause analysis, and coordinate fixes with engineering and external contacts; update adapter rules and mappings as needed.
- Drive onboarding programs for new partners: scoping, effort estimation, timelines, acceptance criteria, go/no-go readiness and postgolive handoff to operations/support.
- Support compliance and security review processes: consent flows, data retention, audit trails, AML/KYC considerations for fiatcrypto rails, and participate in penetration test and vulnerability remediation activities.
- Liaise with product, sales and customer success to clarify integration scope, provide technical input for RFPs/SOWs, and deliver technical onboarding and training to clients and internal stakeholders.
- Stay current on banking and crypto standards (ISO 20022, SWIFT, ACH/SEPA/Fedwire, token standards) and recommend improvements to integration patterns and platform capabilities.
We'd Love to See
- Bachelor's degree in Computer Science, Engineering or equivalent experience; relevant certifications a plus.
- 4+ years handson experience integrating with bank or FI systems and/or crypto services; proven experience working directly with client FIs to elicit requirements and own integrations endtoend.
- Demonstrated ability to translate client business and technical requirements into detailed technical specifications, acceptance criteria, and engineering tasks.
- Handson experience implementing adapter/transform rules in middleware, iPaaS or API gateway platforms (MuleSoft, Boomi, Apigee, Kong, custom mapping scripts).
- Deep experience with RESTful APIs and API design: OpenAPI/Swagger, versioning and backward compatibility.
- Strong data skills: JSON and XML, data modeling, schema validation, fieldlevel mapping and transformations; familiarity with ISO 20022 and payments schemas a strong plus.
- Solid knowledge of authentication and security standards: OAuth2, JWT, mutual TLS/client certificates, HMAC, PKI, TLS 1.2/1.3.
- Practical experience bridging modern REST/RPC interfaces with legacy banking protocols (SOAP, ISO 8583) and implementing middleware translations.
- Proficiency with integration/testing tools: Postman, SoapUI, Swagger Editor, API gateways, CI/CD pipelines, and container basics (Docker); familiarity with monitoring/observability tools for production integrations.
- Excellent communication and stakeholder management skills—comfortable running technical workshops, conducting partner walkthroughs, and conveying technical requirements to engineering and nontechnical teams.
- Strong problem solving, analytical skills and attention to detail; ability to manage multiple concurrent onboarding projects and meet deadlines.
- Willingness to participate in occasional offhours/oncall support and coordinate crosstimezone work with external partners.
- Nicetohave: domain knowledge of DeFi/DEX integrations, MPC/HSM certifications, smart contract development/auditing experience, and cloud platform experience (AWS).
These are not strict requirements to thrive in this role. We believe that people can learn and understand technologies if they are willing. We encourage you to still apply if some of the requirements are missing or lacking.
