Job summary

BytesBrains is seeking a senior architect to own how Cruise, domains, and business email fit together under real load. You will translate product intent into durable boundaries, contracts, and failure modes, treating agents as first-class customers.

You will lead design reviews and shape APIs that return structured errors for agents, while guiding integrations with external providers and ensuring cost-aware, fail-closed choices.

Qualifications

• 10+ years building production software with architecture ownership.
• Proven system design under load with multi-tenant boundaries.
• Experience with cloud backends and services.
• Ability to write precise technical prose and lead design reviews.
• Strong TypeScript/Node.js and web frontend collaboration.

Responsibilities

• Design end-to-end architectures for multi-product SaaS staying available under load.
• Set availability, operability, retries, and runbooks.
• Write and review architecture decisions (APIs, auth, secrets, billing) to keep trade-offs explicit.
• Shape OpenAI-compatible APIs so agents get structured errors, not prose-only failures.
• Guide integrations with external suppliers and fail-closed switches.
• Review critical designs for security, cost, scale.
• Raise ADR quality, diagrams, and handoffs for ship-ready knowledge.

Job description

Own architecture for high-scale, high-availability products - Cruise, domains, and business email - with agent-first contracts and fail-closed trade-offs.

Work mode Remote (India)

Experience 10+ years

Compensation ₹45-65 LPA

Employment Full-time

About the role

You will own how BytesBrains’ products fit together under real load: Cruise (our LLM API gateway), domains, and business email - plus the surfaces humans and AI agents both call. You have designed and operated high-scale, high-availability systems before, and you turn product intent into durable boundaries, contracts, and failure modes - not slide decks. The work matters because we treat agents as first-class customers: every design must be machine-usable, cost-aware, and fail closed when the supplier or the budget says no.

What you will do

• Design end-to-end architectures for multi-product SaaS that must stay available under load - tenancy, trust boundaries, and how callables, gateways, and UIs share one contract
• Set the bar for high availability and operability: failure domains, retries, degradations, observability, and runbooks that a human or agent can act on
• Write and review architecture decisions (APIs, auth, isolation, secrets, billing/ledger) so trade-offs and refusals stay explicit
• Shape OpenAI-compatible and reseller-facing APIs so agents get structured errors they can branch on, never prose-only failures
• Guide integrations with external suppliers (LLM providers, OpenSRS, email hosts) using environment-scoped credentials, rate limits, and fail-closed switches
• Review critical designs and PRs for security, cost, scale, and “absence means unknown” - not silent defaults
• Raise the quality of ADRs, diagrams, and handoffs so the next person can ship without tribal knowledge

What you will need

• 10+ years building production software, including ownership of architecture on high-scale, high-availability products or services
• Proven system design under load: tenancy, authn/authz, idempotency, async workflows, capacity, and clear API contracts (OpenAPI or equivalent)
• Hands-on experience keeping production systems available - SLOs, incident response, graceful degradation, and supplier or dependency failure
• Strong judgement on cloud backends (e.g. Firebase/GCP or similar): rules, secrets isolation, and what must never sit on a customer-readable document
• Ability to write precise technical prose and lead design reviews without hiding risk behind jargon
• Comfort collaborating in a small remote team that ships TypeScript/Node services and modern web front ends

Nice to have

• LLM gateways, agent tooling, or OpenAI-compatible proxy experience (routing, spend controls, multi-provider fallback)
• Registrar, hosted-email, or other reseller API integrations at production volume
• Next.js (or similar) + Cloud Functions (or equivalent serverless) in production
• Public technical writing, ADRs, or open-source architecture work

How we hire

• A 10-minute introductory call.
• A practical task: you commit work to a public GitHub repository and share the pull request.
• A 25-minute final conversation.

What we offer

• Ownership of real product architecture on systems that must stay up - not advisory theatre
• Direct impact on Cruise and the platforms agents can buy from and call
• Remote-first India work with a small, high-context team
• Compensation in the published ₹45-65 LPA band, negotiated in the final round within that commitment
