Senior Full Stack Developer Node JS/ React

Job Description

Tirnu is building a unified Embedded Banking and Digital Asset platform. Users connect multiple bank accounts, access tokenized and crypto investments, manage digital assets, and monitor spending in real time through intelligent automation.

We are bridging traditional finance and blockchain infrastructure through one secure, scalable system.

This is serious infrastructure. Not a prototype. Not a demo.

The Role

We are hiring a Senior Full Stack Engineer to take ownership of core fintech and crypto systems.

You will design, build, and scale backend and blockchain-integrated infrastructure that handles real financial transactions. This role requires execution strength, system thinking, and technical maturity.

You will be responsible for building systems that are secure, performant, and production-ready.

What You Will Build

• Banking integration services
• Crypto wallet infrastructure
• Blockchain transaction lifecycle management
• Tokenized asset modules
• High-performance APIs
• Data indexing and search services
• Scalable microservices architecture

You will work across the full stack but with strong backend and infrastructure responsibility.

Core Responsibilities

• Architect and develop backend services using Node.js and TypeScript
• Design secure and scalable APIs deployed on AWS (EC2, Lambda, API Gateway, S3)
• Integrate blockchain networks (EVM and non-EVM where applicable)
• Implement wallet logic, transaction monitoring, and asset tracking
• Build and optimize NoSQL database models (MongoDB / DynamoDB)
• Implement Elasticsearch for advanced indexing and search performance
• Structure services using modular microservices architecture
• Ensure high system reliability, observability, and logging standards
• Troubleshoot and resolve performance and infrastructure bottlenecks
• Maintain clean, structured, and production-grade code standards

Technical Requirements

• 4+ years experience building production-grade backend systems
• Strong expertise in Node.js and TypeScript
• Practical experience with blockchain integrations and crypto APIs
• Understanding of transaction lifecycle, gas models, and wallet systems
• Experience with AWS cloud infrastructure
• Strong NoSQL database design and performance optimization skills
• Experience working in structured Git workflows and CI/CD environments
• Familiarity with Elasticsearch and distributed system design

Mindset We Expect

• Very Strong ownership mentality
• Accountability for outcomes
• Ability to diagnose and solve problems independently
• High execution discipline
• Attention to detail in financial systems
• Clear and direct technical communication

We operate in fintech and digital assets.

 Systems must work.

 Testing must be thorough.

 Execution must be clean.

Why Join Tirnu?

You join Tirnu because you want to WORK.

No politics.

No time-wasting.

No comfort-zone engineering.

We want builders with energy, drive, and an awesome attitude.

People who:

• Take initiative
• Deliver results
• Thrive under responsibility
• Want to build serious infrastructure

If you want to operate at a high standard and build something meaningful in embedded finance and crypto this is your place.

Tirnu hires for execution.

If that’s you, apply.
