Senior AI Native Software Engineer in London

At Remitly, we believe everyone deserves the freedom to access, move, and manage their money wherever life takes them. Since 2011, we've tirelessly delivered on our promise to customers sending money globally, providing secure, simple, and reliable ways to manage their money, ensuring true peace of mind. Whether it's supporting loved ones back home, growing a business across continents, or pursuing new opportunities abroad, we're not just here to move money— we're here to move our global customers forward.

We're looking for builders, reimaginers, and global thinkers who want to work at the intersection of technology, trust, and transformation. If that's you and you're ready to do the most meaningful work of your career—we invite you to join over 2,800 passionate Remitlians worldwide who are united by our vision to transform lives with trusted financial services that transcend borders.

About the Role: The Treasury team manages Remitly's global funding operations — optimising liquidity positions, managing funding corridors, and ensuring capital is available wherever it's needed. Reporting to the Head of Treasury Analytics & Data Science (London), this London-based (hybrid) role sits at the intersection of LLMs, Treasury operations, and data infrastructure.

We're looking for a builder who moves fast from idea to production — someone who can own agentic systems end-to-end and directly increase the operational capacity of the Treasury team.

You Will Build:

• Treasury Agent Automation
• Cash flow monitoring agents: intraday cash position tracking, reconciliation, variance flagging, and automated daily reports across accounts and currencies.
• Funding execution agents: instruction routing, approval workflows, payment scheduling, cut-off monitoring, and settlement tracking — encoded with business rules and risk parameters.
• Narrative agents: auto-generated end-of-day and intraday funding commentary, exception summaries, and context-aware alerts delivered to the right stakeholders.
• Discovery-to-deployment pipeline: structured sessions with Funding operators to identify manual tasks, then ship agents that eliminate them — reporting packs, utilisation dashboards, liquidity summaries.
• Embed within the Funding team at the outset — running existing workflows end-to-end alongside operators to develop a first-hand understanding of day-to-day processes, limitations, and pain points before a single agent is scoped or built.
• Agent Infrastructure & Growth
• Build reusable, modular agent components and tool libraries that scale as Remitly expands into new markets and corridors.
• Contribute to Treasury-wide agent governance standards, evaluation frameworks, and shared infrastructure.
• Research and recommend emerging LLM capabilities and agentic tooling to keep the Funding function ahead of the curve.
• Partner closely with the Treasury Engineering team to develop the data accuracy, completeness, and timeliness required by Treasury Agents.

You Have:

• Advanced proficiency with coding agents across complex development scenarios.
• Experience architecting multi-service systems, including complex persistence, integrations, and scaling.
• Understanding of distributed systems tradeoffs and cloud-based infrastructure design.
• AI tool fluency: orchestrators, automated workflows, comprehensive evaluation pipelines.
• Advanced systems architecture expertise across the full technology stack.
• Proficiency in customer discovery techniques and ability to connect technical work to business outcomes.
• Competence with design thinking, analytics tools, and funnel analysis.
• Experience guiding others on AI-first development approaches.
• Expertise in experiment modelling, funnel analysis, and data-informed decision making.
• Track record of mentoring others and elevating team capabilities.

Nice to Have:

• Treasury, fintech, or payments domain knowledge (cash positioning, FX, liquidity).
• LLM observability tools: LangSmith, Arize, Weights & Biases.
• AWS (S3, Glue, Redshift, Lambda); TMS/financial data providers (Bloomberg, Kyriba).
• Startup, founder, or cross-functional multi-product experience.

Our Benefits:

• Paid Vacation Days
• Health insurance
• Commuter benefit
• Employee Stock Purchase Plan (ESPP)
• Mental Health & Family Forming Benefits
• Continuing education and corridor travel benefits
