Technical Architect - Backend & AI
First seen by Alion on Sep 2, 2026.
About the Role :
This is a senior, high-impact role designed for a pragmatic, battle-tested Technical Architect with strong hands-on development experience. You will work amongst the sharpest minds in the financial fraternity to build a next-generation platform vision. At Mintoak, we embrace simplicity and evolutionary design over convoluted, heavy top-down architecture solutions. We maintain a strong preference for Open Source (FOSS) and building over buying wherever viable.
This role requires a hands-on Technical Architect who stays in the trenches. The individual will combine the absolute best traits of a technical visionary and an execution-focused leader, bringing the capability to structure robust backend engines while aggressively deep-diving into complex production environments to debug and resolve issues at the highest speed.
Key Responsibilities :
- Drive, own, and execute multiple next-generation platform initiatives.
- Ensure backend architectures are structurally designed for massive scale, extreme availability, and high performance using Java microservices and strict AI and API-first design principles.
- Act as the technical design authority ensuring seamless data flow, state management, and consistency across Java backend services, React Web platforms, and Mobile/POS applications (Android & C++ kernels).
- Personally lead the hands-on prototyping, design, and integration of AI/ML utilities into core production pipelines (e.g., smart reconciliation engines, fraud pattern recognition, and transaction optimization).
- Act as the go-to responder for high-priority production incidents.
- Personally drive down MTTR by debugging critical technical issues within a complex stack involving Spring Boot microservices, Docker containers, and AWS environments.
- Reinforce XP practices such as Test-Driven Development (TDD), refactoring, and clean code.
- Devise processes and mechanisms to ensure expected uptime and platform resilience.
- Partner closely with Product Management and clients to scope out releases, translate business goals into technical execution charts, and deliver high-quality outputs on predictable schedules without trading off quality for velocity.
Technical Skills :
- Core Language & Frameworks : Deep hands-on mastery of Java and the Spring Boot ecosystem.
- Cloud & Orchestration : Strong architecture and implementation experience with AWS services, Docker containerization, and Kubernetes for container orchestration.
- Data & Messaging Systems : Expertise in distributed system design using SQL & NoSQL databases and messaging fabrics like RabbitMQ & NATS.
- AI / ML Pipeline : Practical proficiency in integrating AI utilities, LLMs, or foundational frameworks into high-throughput backend infrastructure.
- Observability : Practical experience deploying observability frameworks such as Prometheus and Grafana.
Qualification :
- 10+ years of technical experience in Product-Led, Tech-First companies, with a significant background operating in fast-growing Fintech or transaction-heavy payment processing sectors.
- BE / B. Tech / MCA / M. Sc. from a premier or tier-1 / tier-2 institute.
