Hybrid
This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Treasury Engineering Team Lead based in France.
As a Treasury Engineering Team Lead, you will lead the engineering team responsible for building and scaling the financial infrastructure that supports complex global money movements.
You will oversee the systems connecting banking partners, processing financial data, reconciling transactions, and ensuring accurate accounting across thousands of bank accounts.
Leading a multidisciplinary team of approximately 10 engineers across backend, frontend, and QA, you will shape technical direction, drive delivery, and support individual growth.
You will play a critical role in strengthening financial controls, improving reconciliation accuracy, and ensuring reliable financial reporting in a high-growth fintech environment.
Working closely with Finance, Accounts Payable, and other engineering teams, you will translate business needs into scalable technical solutions.
You will also champion AI-powered engineering and automation, introducing intelligent tools to improve monitoring, investigation, and operational efficiency.
This is an opportunity to combine hands-on technical leadership, fintech expertise, and strategic influence while building systems that support the future of global financial operations.
Lead, develop, and grow a multidisciplinary Treasury Engineering team of approximately 10 professionals across backend, frontend, and QA.
Define team structure, hiring priorities, and recruitment processes to attract and retain strong engineering talent.
Coach engineers through regular feedback, individual development plans, and opportunities to strengthen their technical expertise and production ownership.
Establish priorities, coordinate delivery plans with Finance and Engineering stakeholders, and ensure the team focuses on measurable business outcomes.
Oversee the development, maintenance, and scalability of banking integrations, transaction reconciliation systems, and data pipelines supporting money movements, tax payments, and cash management.
Ensure end-to-end visibility of financial transactions, from the initial user request through settlement and final accounting entries.
Develop monitoring and reconciliation mechanisms to identify and prevent financial discrepancies, duplicate transactions, processing delays, mismatched balances, and integration failures.
Lead complex technical investigations across payment service providers, ledgers, wallets, payouts, cards, and cryptocurrency payment infrastructure.
Address technical incidents at their root cause by improving code, data models, and integrations rather than relying solely on temporary fixes.
Ensure financial operations are reliable, observable, idempotent, and safe to retry, translating post-incident findings into preventive controls, automated tests, and monitoring solutions.
Drive the adoption of AI agents and automation tools to support alert triage, investigation, troubleshooting, and resolution verification.
Design safe AI-driven workflows with appropriate human oversight, maker-checker validation, escalation mechanisms, and comprehensive audit trails.
Act as the bridge between Finance and Engineering, translating financial requirements into technical priorities and communicating engineering constraints in business-friendly terms.
Balance operational urgency with long-term engineering quality, ensuring that financial systems remain reliable as transaction volumes and business complexity increase.
Monitor team performance through key indicators, including financial close timelines, reconciliation accuracy, transaction completion rates, and alert quality.
Participate in a shared on-call rotation and help maintain the reliability and availability of critical financial systems.
Significant professional experience in software engineering, including at least 1 year of experience leading engineering teams and managing delivery in complex technical environments.
Mandatory experience building fintech systems or working within the financial technology sector.
Proven experience hiring, mentoring, and developing engineers, providing constructive feedback, and supporting professional growth.
Strong backend engineering expertise, ideally with Node.js and TypeScript. Candidates with other server-side technology backgrounds are welcome, provided they are comfortable working with Node.js and TypeScript.
Solid SQL and database engineering knowledge, including practical experience with PostgreSQL.
Strong understanding of production systems and experience troubleshooting high-volume applications, identifying root causes, and resolving complex technical incidents.
Good knowledge of concurrency, idempotency, retry mechanisms, queues, and eventual consistency.
Experience designing and maintaining reliable, scalable, and observable financial or transactional systems.
An AI-native engineering mindset, with practical experience using AI coding assistants and agent tools such as Claude Code, Cursor, or Codex.
Ability to orchestrate multiple AI agents, create clear technical specifications and reusable agent instructions, and critically review AI-generated outputs while understanding when human intervention is necessary.
Excellent cross-functional communication skills, with the ability to explain complex technical and financial issues to both engineering and finance stakeholders.
Strong leadership and organisational abilities, particularly when managing broad scopes, setting priorities, and balancing urgent business requirements with long-term technical quality.
A proactive, solution-oriented mindset, with a strong sense of ownership and the ability to build resilient teams that perform effectively under pressure.
A customer- and people-focused approach, recognising the importance of reliability and accuracy in every financial transaction.
Comfortable working in an international environment, with core working hours overlapping with the EMEA Treasury team. Candidates based in EMEA are preferred, with openness to candidates in India.
Willingness to participate in a shared on-call rotation.
Additional experience that would be an advantage:
Experience with payment systems, financial ledgers, double-entry accounting, transaction reconciliation, card issuing, stablecoins, or cryptocurrency payment infrastructure.
Familiarity with payment service provider and banking integrations, including webhooks, settlement files, and payment returns.
Experience building and deploying LLM-based agents, tool servers such as MCP, evaluation frameworks, or retrieval systems in production.
Previous Site Reliability Engineering (SRE) or on-call experience within regulated industries or financial services.
Competitive, market-aligned salary based on experience, skills, and geographical location.
Salary offers are localised to the candidate's country and currency, using market-aligned conversion rates.
Equity and stock grant opportunities, depending on role, employment status, and location.
Additional perks and benefits tailored to local employment arrangements and country-specific requirements.
Access to optional flexible office membership through IWG.
Opportunity to work in a globally distributed, multicultural environment alongside international engineering and finance professionals.
Career development opportunities through exposure to complex fintech challenges and large-scale financial infrastructure.
Opportunity to influence technical strategy, build and develop an engineering team, and drive AI-powered innovation.
Flexible working arrangements aligned with the team's international operating model.
