Aerchain - Senior Architect

Role : Senior Architect

Employment Type : Contractual

Location : Bangalore Work From Office (WFO)

About Aerchain :

Were rewriting the rules of procurement with an AI-first platform that powers $20B+ in enterprise spend. From $4M ARR today to $25M ARR and beyond, our mission is to build enterprise-grade, AI-first procurement software for global enterprises across manufacturing, FMCG, and services.

About the Role :

You own the architecture of assigned source-to-pay domains on an AI-first procurement platform. You make the structural calls in your domains, define the standards product managers build inside, and take the hard architectural problems from framing through to production. In our model, product managers build with AI and architects define the guardrails they build inside, so your standards directly shape how quickly and safely the product ships. You work closely with the Lead Architect, the CTO and the module owners in your domains. You report to the Lead Architect.

What Youll Drive :

Domain Architecture Ownership :

- Own the architecture of your assigned source-to-pay domains: data models, service boundaries, integration patterns.

- Make the structural calls in your domains and carry them through to production.

- Know your domains deeply enough to say where they will break next, and act on it.

Architectural Problem Delivery :

- Take architectural problems end to end: cutting response time on a module, reworking a data model, removing a structural bottleneck.

- Propose the work, make the case, and own it through implementation and into production.

- Pressure-test your own recommendations before they reach review.

Standards & Guardrails :

- Define and maintain the patterns and standards product managers build inside your domains.

- Keep guardrails proportionate so they catch real problems while delivery stays fast.

- Review what is being built against those standards and identify the gaps.

- Decide exceptions quickly where a module genuinely requires one.

Working With Product :

- Work directly with module owners: understand what they are building and why, and make the architecture serve it.

- Demonstrate the standard by building to it, so product managers have a reference to work from.

- Support the Lead Architect on platform-wide stability, roadmap and security where they touch your domains.

Technical Skills & Expertise :

- Programming : Java and Python.

- Backend : Spring Boot and Microservices Architecture.

- Cloud : AWS.

- Architecture : System Design, Distributed Systems, and API Integrations.

- Database : PostgreSQL and MySQL.

- AI : LLMs and Agentic AI architectures.

Youll Thrive Here If :

- 812 years in engineering with real architectural ownership of a domain or product area.

- You go deep on problems others route around, and you finish them.

- You hold a standard while delivery keeps moving.

- You are comfortable in a model where product managers build with AI and architects set the guardrails.

- You use AI as a core part of how you work, and raise the bar for those around you.

- You stay with an architectural decision until it is proven in production.

- Bonus: exposure to enterprise SaaS, complex B2B environments, or procurement tech.

Whats In It For You :

- Architectural ownership of real source-to-pay domains, with authority over the structural calls.

- A direct line to the Lead Architect and CTO, with no bureaucracy between your judgment and the decisions that matter.

- A build model to shape: AI-first product managers building inside guardrails you define.

- A culture where problem solving
