Job description

Team: Fimple Delivery

Fimple is a product company building a cloud-native, highly composable and extendible platform. It covers the full platform needs of digital, disruptive and new financial players who need to move fast. Our solution is modern, API-native and built around an ecosystem with strong marketplace support, so financial institutions can grow in a fast-changing market.

We are looking for an Implementation Engineer to join our Fimple Delivery team in Istanbul. You will take part in core banking implementation projects from start to finish. You will work closely with our clients to understand their business needs, set up the Fimple platform to match their banking products and processes, and help them go live successfully.

We are not looking for a traditional core banking implementer. We are looking for agile, openminded people who are curious to learn and improve, don’t just repeat old methods, and always look for a better, faster way to get things done. You should use AI tools in your daily work and turn complex banking needs into simple, practical solutions.

Who You Are

• Open to innovation: you enjoy new technologies and new ways of working, and you don’t cling to old methods

• AI-savvy: you already use AI tools (e.g., ChatGPT, Claude, Copilot) to analyze requirements, write documents, prepare test scenarios, investigate issues and speed up your work

• Solution-oriented: you focus on solving the problem, not on listing obstacles

• Flexible and practical: you adapt quickly when priorities change and look for the simplest solution that works, not the most complicated one

• Ownership mindset: you take responsibility and carry things through to the end

• Fast learner: you pick up new products, domains and tools quickly

Key Responsibilities

• Take part in end-to-end core banking implementation projects, from requirement gathering to go-live and post-go-live support

• Run workshops with clients to understand their banking products, business processes and regulatory needs

• Configure and set up banking products and parameters on the platform, such as accounts, deposits, loans, payments, cards, customer onboarding, fees and charges, and accounting rules

• Use AI-powered tools and automation to speed up analysis, documentation, testing and issue resolution

• Write clear, concise functional documents, including business requirements, functional specifications, configuration workbooks and process flows

• Prepare test scenarios and support SIT and UAT phases with clients

• Support data migration activities by mapping and validating legacy data against the platform’s data model

• Work with product, development and QA teams to deliver solutions and handle change requests

• Train client users and create user guides

• Analyze and troubleshoot functional issues during implementation and after go-live

• Suggest improvements to our delivery processes and help build a faster, smarter way of implementing core banking

Qualifications

• Must be currently living in Istanbul, Türkiye

• Bachelor’s degree in Computer Engineering, Software Engineering, Management Information Systems, Banking or a related field

• 3+ years of experience in banking, in banking operations, core banking implementation, functional consulting or business analysis

• Solid knowledge of banking business processes, such as retail and/or corporate banking, deposits, lending, payments, general ledger and accounting, and customer lifecycle

• Core banking business knowledge is a must: you understand how core banking products, accounts, transactions and accounting work end to end

• Understanding of how banking systems work, including products, parameters, end-of-day processes and integrations

• Hands-on experience with one or more core banking systems

• Hands-on use of AI tools in your daily work

• Examples of how you used AI or automation to improve a process or save time

• Basic technical skills: reading APIs (REST/JSON), writing SQL queries, understanding system integrations
