01Key Responsibilities
- Solution design, end-to-end. You'll own how the chat interface, the AI orchestration layer, and the backend all fit together not just one piece of it.
- Integration design across three systems: (1) The existing mobile app (credential/session handling, secure authentication hand-off, native navigation hand-off) (2) The LLM/AI provider (the language model powering the conversation), & (3) Backend service APIs (account actions, balance enquiry, transaction history, request management, support workflows, and more)
- Setting the technical bar for session security, data privacy, response speed, and system resilience and making sure the team builds to it.
- Approving the tech stack and deployment approach, and designing how every chat-driven action gets logged for audit purposes.
- Hands-on delivery Take direct ownership of the most complex and high-stakes components of the solution, including (1) Secure credential hand-off: Design and implement secure authentication flows that ensure the chat interface never collects, accesses, processes, or stores users sensitive authentication credentials. This is a strict, non-negotiable security requirement. (2) AI guardrails: Build robust guardrails to protect and mask personal/sensitive data, keep AI interactions within defined boundaries, and handle ambiguous, incomplete, or unclear user requests safely and effectively.
- Running the day-to-day engineering process: breaking work into sprint-ready tasks, running design/code reviews, unblocking developers, and owning the CI/CD (build & deployment) pipeline.
- Being the primary technical voice - explaining design decisions and trade-offs in plain terms, gathering requirements, and building confidence that the solution is being built the right way.
- Mentoring the team this is a lead role, not a purely individual-contributor one. You'll be reviewing code, unblocking teammates, and raising the technical bar for the group.
What We're Looking For
Must-haves:
- 8+ years of hands-on software engineering experience, including real experience leading a technical team (not just contributing to one).
- Flutter hands-on, production mobile development experience. This is a build-and-review role for the mobile chat module, not just high-level oversight.
- Solid backend development in Node.js or Python comfortable designing how a system routes requests, calls external APIs, handles errors and retries, and logs everything for compliance.
- WebRTC experience real-time audio/video/voice streaming, since this interface needs to support live voice interaction end-to-end, not just text.
- AI Speech-to-Text (STT) and Text-to-Speech (TTS) hands-on experience integrating STT/TTS so the interface can convert spoken input to text and generate natural spoken responses.
- Comfort owning security-sensitive design session management, data masking, audit logging even if you haven't worked specifically in this industry before.
- Proven client-facing communication skills real experience explaining technical decisions to non-technical stakeholders, running requirement discussions, and getting sign-off on deliverables.
- Agile delivery experience comfortable breaking down work, running or contributing to sprint ceremonies, and managing a live backlog.
Strongly preferred:
- Experience in banking, fintech, or another regulated industry you don't need to know any specific payment standard, but experience working under strict compliance/data-handling rules is a major plus.
- Direct, hands-on experience integrating LLM/Generative AI APIs into a real product prompt design, intent recognition, guardrails, and handling AI responses safely and reliably.
Nice-to-haves:
- Chatbot building experience prior work building a conversational/chat interface for financial or transactional workflows.
- Experience with Kubernetes/Docker and CI/CD pipeline ownership. .
