Lead Fullstack Developer

Mira is building the foundational trust and verification layer for agentic commerce - the emerging landscape where autonomous AI agents interact, transact, and deliver value across modern digital systems. Our work extends into next-generation consumer finance, blending intelligent automation, verifiable execution, and new forms of digital value movement.

We operate as a senior, high-caliber engineering team that ships foundational infrastructure for intelligent consumer experiences, where correctness, reliability, and clarity of execution matter deeply.

We are building a consumer-facing financial product at Mira.

Think crypto-native neobank + agentic automation, where large parts of money movement, compliance, and execution are stitched together via existing providers - but orchestrated with strong guarantees, clear invariants, and excellent user experience.

This is a 0 to 1 product. Architecture decisions made early will compound for years.

We’re looking for a Lead Architect / Lead Full-Stack Engineer to act as a technical owner for this product.

You will define and build the core product architecture across backend, integrations, and frontend surfaces. This role is not about inventing new primitives - it’s about correctly and safely stitching together high-risk systems (money movement, KYC, wallets, verification, agent flows) into a coherent, scalable product.

You’ll work closely with product leadership to shape the technical direction, while staying deeply hands-on in production code and also support in building and leading the technical team.

WHAT YOU WILL DO:

Your primary responsibility is to design, build, and own the core full-stack system end to end.

Specifically, you will:

• Architect and implement backend systems for correctness-critical workflows, including ledgers, balances, transaction state, and orchestration logic.
• Design and build integration-heavy systems, stitching together KYC, wallet providers, verification services, vaults, and external financial APIs.
• Own system invariants and failure modes: ensuring money movement, retries, reconciliation, and edge cases behave safely under stress.
• Build and evolve agentic automation flows that coordinate execution across multiple systems while remaining observable and debuggable.
• Develop core frontend surfaces (web, admin, internal tools) and collaborate closely with React Native engineers for the consumer app.
• Set up and maintain DevOps foundations: environments, CI/CD, monitoring, alerts, and operational playbooks.
• Act as a technical decision-maker and mentor, raising the bar for system design, code quality, and reliability across the team.
• Collaborate with the broader engineering and product team on shared primitives around verification, correctness, and trust.

WHAT YOU BRING:

You are a senior engineer who has built and owned real systems where failure is expensive.

You likely have:

• 5–8+ years of full-stack engineering experience, with strong depth on the backend.
• Prior experience in consumer fintech, payments, wallets, or financial infrastructure, where ledgers and state correctness mattered.
• Deep experience with schema design, data modeling, consistency models, and fault-tolerant systems.
• Strong systems thinking: you naturally reason about invariants, race conditions, retries, idempotency, and data integrity.
• Hands-on experience integrating and operating third-party APIs in production (KYC, payments, identity, compliance, etc.).
• Solid DevOps instincts - comfortable owning deployments, infra decisions, and operational reliability.
• Frontend experience with modern JS/TypeScript frameworks (React); enough to build and reason about product UX, even if you’re backend-leaning.
• Comfort operating in ambiguity and 0→1 environments, where the problem is still being shaped alongside the solution.
• A strong sense of ownership - you don’t wait for specs; you help define them.

NICE TO HAVE:

• Experience working with crypto or blockchain-adjacent systems, even if via integrations rather than protocol design.
• Familiarity with React Native or close collaboration with mobile teams.
• Prior work building consumer-scale systems or financial-grade infrastructure.
• Prior exposure to agent-like workflows, automation engines, or distributed orchestration systems.

WHY THIS ROLE MATTERS:

This is a keystone hire.

The person in this role will:

• Shape how money moves through the system
• Define early architectural patterns
• Prevent painful rewrites later by getting fundamentals right now

If you enjoy building serious systems with real-world consequences - and want to operate at founder-level ownership inside a small, elite team - this role will stretch and reward you.

WHAT WE OFFER:

• Competitive compensation.
• High ownership and the opportunity to shape product direction.
• Direct impact on foundational cryptographic and blockchain infrastructure.
• A collaborative team that values clarity, autonomy, and velocity.

Note: This role can be remote; however Bengaluru or Mumbai candidates will be prioritized.

Note: We are looking for real, hands-on experience—not certifications or copy-paste portfolios. Selected candidates will be given a short real-world task to evaluate skills before interview.

Key Responsibilities

• Design, build, and maintain scalable full-stack applications using MongoDB, Postgresql, Express.js, React.js, and Node.js
• Develop RESTful APIs and integrate them with frontend systems
• Collaborate with designers and project managers for timely project delivery
• Optimize code for performance and scalability
• Troubleshoot, debug, and upgrade applications as needed
• Follow Git-based workflows for version control

Must-Have Skills

• Strong hands-on experience in:
• React.js with hooks, context API, component architecture
• Node.js with Express.js
• MongoDB (CRUD operations, schema design) & Postgresql
• API development and integration
• Strong JavaScript fundamentals (ES6+)
• Basic understanding of deployment (e.g., cPanel, Vercel, Heroku, or VPS)
• Git and GitHub for code versioning

Good-to-Have Skills

• Knowledge of Redux or any other state management tools
• Experience with Next.js or TypeScript
• Familiarity with Tailwind CSS or Material UI
• Experience integrating third-party APIs (e.g., payment gateways, social logins)

Who Should Apply

• You’ve worked on real client projects or have built and shipped working applications.
• You are disciplined and take ownership without constant follow-up.
• You are not here to "fake it till you make it"—you’re here to grow with a real team.

Experience: 2-3 years of experience in Python, NodeJS, MySQL, ReactJS, NextJS technologies.
