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.
