Intergrations Support Engineer, Fintech

Optasia is a fully-integrated B2B2X financial technology platform covering scoring, financial decisioning, disbursement & collection. We provide a versatile AI Platform powering financial inclusion, delivering responsible financing decision-making and driving a superior business model & strong customer experience with presence in 30 Countries anchored by 7 Regional Offices.

We are seeking for enthusiastic professionals, with energy, who are results driven and have can-do attitude, who want to be part of a team of likeminded individuals who are delivering solutions in an innovative and exciting environment.

As an Integration Support Engineer (ISE) you will evaluate operational changes proposed by third‑party systems integrated with Optasia, gauge their technical impact, and devise the corresponding rollout plans. You will also assume full responsibility for ensuring that every new or existing project meets the technical prerequisites required to start the System Integration Testing phase, working in close collaboration with — and under the architectural guidance of — a Solutions Architect.

This position is strictly focused on integration readiness: it excludes live production support, low‑level solution design, software development, and the upkeep of test environments.

What you will do

• Evaluate change requests—spanning platform upgrades, protocol migrations, and topology adjustments—by quantifying technical impact and rollback risk, defining mitigation steps, securing a jointly endorsed rollout plan with internal and external stakeholders, and consulting the Solution Architect whenever the change requires modifications to the solution design.
• Compile and convey the configuration and development prerequisites that third‑party systems must deliver for System Integration Testing readiness, liaising directly with their owners.
• Execute a concise suite of HTTP based API smoke tests (REST, SOAP, RPC etc.), troubleshoot anomalies, and escalate unresolved gaps to third‑party counterparts and the Solution Architect.
• Draft IAT test cases for execution by Optasia developers, under Solution Architect's guidance.
• Maintain clear traceability: update Jira and Confluence records for change requests and for SIT preparations.
• Drive continuous improvement by converting lessons learned into reusable templates — covering change‑request assessments, SIT readiness checklists, and smoke‑test scripts — so future integrations follow streamlined, standardised practices.
• Transition smoothly from ISE to Associate Solution Architect once you demonstrate design aptitude and business acumen.

What you will bring

• 1–3 years in system integration, API testing, technical support, or QA (fintech/telco a plus)
• Solid grasp of REST/SOAP, HTTP, JSON/XML; hands-on with Postman, SoapUI, or cURL
• Comfort with network basics (IPs, ports, TLS, credentials)
• Bachelor in Computer Science, Engineering, or related field
• Fluent written and spoken English for clear communication with international stakeholders
• Detail oriented, proactive communicator able to juggle parallel projects

Will be considered as plus

• Exposure to banking APIs, telecom OCS/charging interfaces

• Basic SQL or scripting for quick data checks

• Experience with Jira, Confluence, or comparable tracking/documentation tools

• Experience in linux, bash scripting etc.
