About the job
We are looking for an early, high-caliber engineer to help architect and build the core DeepInspect platform.

You will work directly with the founder and have significant ownership over architecture, implementation, and technical direction. If you like ambiguity, hard problems, and building foundational systems from scratch, this role is for you.

What You Will Work On
Early system design decisions that will shape the product long-term, including data models, service boundaries, and failure semantics
Designing and building low-latency, high-throughput backend services that sit on critical request paths
Core backend and control-plane services with a strong emphasis on correctness, determinism, and predictable behavior under load
Security evaluation and enforcement pipelines where every decision must be explainable, auditable, and safe by default
Secure multi-tenant architectures with strict isolation guarantees and minimal trust assumptions
High-signal audit logging and evidence generation systems designed for regulated environments
Runtime systems that must fail closed, degrade gracefully, and behave consistently under partial failure
Performance tradeoff analysis across CPU, memory, network, and storage layers as the system evolves
Making deliberate tradeoffs between simplicity, performance, and extensibility in an early-stage system
What We Are Looking For
5–8 years of experience building backend or platform systems
Strong fundamentals in:

Distributed systems and concurrency
APIs and service design
Security concepts (authn, authz, isolation, trust boundaries)
Performance fundamentals (latency, throughput, backpressure, caching)
Comfortable reasoning about tradeoffs, not just writing code

Able to explain why a design works, not just what it does

Opinionated, but open to debate and evidence

High ownership mindset and comfort operating with incomplete information

You do not need to be an AI expert. You do need to be able to think clearly under complexity.

Tech Stack
Node.js
PostgreSQL
Redis
Docker / Kubernetes
Nginx
Stack will evolve.

Why Join This Early
Direct impact on product and architecture
Real ownership
Exposure to real enterprise security and AI governance problems
Build something that will be audited, regulated, and relied upon
