BUILD THE
INFRASTRUCTURE.
We're building the backbone of developer communication. Distributed systems. High-throughput messaging. Real-time infrastructure. No meetings. Ship code.
Hard Problems. Real Scale.
Distributed Email Relay
Multi-region SMTP relay network with intelligent routing, reputation management, and real-time deliverability optimization.
Real-time Messaging
WebSocket infrastructure handling millions of concurrent connections with presence, typing indicators, and message sync.
Multi-tenant Data Layer
Horizontally scalable PostgreSQL with row-level security, connection pooling, and automated sharding strategies.
Event-Driven Architecture
Kafka-based event streaming with exactly-once semantics, dead letter queues, and complex event processing.
Identity & Access
OAuth 2.0 / OIDC provider with WebAuthn passkeys, TOTP, session management, and enterprise SAML federation.
Edge Delivery Network
Global points of presence with intelligent caching, request coalescing, and automatic failover.
Engineering-First Culture
Code > Meetings
Async by default. We write RFCs, not slide decks. Stand-ups are optional. Ship code, not status updates.
Own Your Domain
Full ownership from design to production. You architect it, build it, deploy it, and monitor it. No handoffs.
Open Source Mindset
We contribute upstream, document everything, and build tools we'd want to use ourselves. Quality over velocity.
Remote & Flexible
Work from anywhere in India. We optimize for written communication and deep work. Overlap when needed, async otherwise.
