About the Role:

We are building systems that operate at scale - high write volumes, real-time state sync, and burst traffic that doesn’t politely warn before it arrives. We are looking for engineers who love owning systems end-to-end, care deeply about performance and reliability, and want to build things that don’t just work - but last. This is not a ticket-execution role, its a system ownership role.

Responsibilities:

Frontend Integration:

• Ship modular Vue 3 UIs that efficiently consume APIs
• Optimize realtime updates and state management (Pinia)
• Improve Core Web Vitals and perceived performance

Observability & Production Ownership:

• Instrument logs, metrics, traces, and alerts
• Participate in on-call
• Debug real production issues
• Drive post-mortems to meaningful closure (not just documents)

Mentorship & Leverage:

• Review code thoughtfully
• Support junior engineers
• Raise engineering standards across the team

Requirements:

• 4+ years of professional engineering experience
• Strong backend-heavy fullstack background
• Deep comfort with Node.js + TypeScript

• CI/CD and containerization familiarity

Nice to Have:

• Pub/Sub or message queue experience
• Event-driven systems exposure
• Domain-driven design familiarity
• Performance optimization work
• Experience reducing infra costs

Sound technical exposure in React, Node, API, Java, JPA, Hibernate, Kafka, REST API,

Postgre DB.

• Strong experience in systems design principles.

• Must have strong exposure in PSQL queries and stored procedures.

• Experience in Lending/Fintech domains will be preferable.

• Design, implement and maintain Java-based applications that can be high-volume and

low-latency.

• Familiarity with browser testing and debugging.

• Analyze user requirements to define business objectives.

• Identify and resolve any technical issues arising.

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.
