Job summary

Hydron Holdings in Kuala Lumpur, Malaysia, is hiring a Senior Software Engineer (AI) to design, build, and ship AI-powered products across our FinTech portfolio, including eKYC and fraud detection. This hands-on senior role combines architecture ownership with technical leadership in a regulated environment.

You will work on AWS serverless systems, large language models, and AI observability while mentoring teammates and driving architectural decisions aligned with product goals.

Qualifications

• 3+ years backend or full-stack engineering with 2+ years AI/ML production experience.
• Strong Python skills with NoSQL, REST APIs, and AWS serverless architecture.
• Experience building LLM-based solutions: prompt engineering, agent-style architectures, and integration with providers such as AWS Bedrock, OpenAI, or Anthropic.
• Experience evaluating and monitoring AI systems—automated testing, quality metrics, and production observability.
• Proven track record designing scalable APIs and distributed systems.
• Understanding of applied ML integration (OCR, biometrics, document validation, or fraud/anomaly detection).
• Excellent problem-solving and communication skills; able to explain complex technical concepts to non-technical stakeholders.
• A team player in an Agile environment, balancing hands-on coding with technical leadership.
• Active interest in AI advancements and industry best practices.

Responsibilities

• Design and implement end-to-end AI systems — inference pipelines, agent workflows, and tool-calling architectures.
• Build LLM-powered features on AWS Bedrock: context orchestration, system prompts, memory, retrieval (RAG).
• Develop and optimize ML components for identity verification and fraud detection.
• Build, scale, and secure microservices on AWS serverless (Lambda, API Gateway, DynamoDB, S3, Bedrock).
• Own evaluation frameworks, guardrails, and AI observability — logging, tracing, and latency/cost-aware fallback strategies.
• Oversee model deployment and performance monitoring for ML and LLM components in production.
• Contribute to the technical roadmap; drive architecture decisions aligned with product and compliance goals.
• Evaluate and integrate third-party services — verification vendors, OCR engines, biometric SDKs, and LLM providers.
• Collaborate with Product Owner, BAs, UX/UI designers, and QA to deliver seamless product experiences.
• Mentor engineers through code review and CI/CD improvements; promote observability and cost efficiency.
