ARKION PlatformStandard

For Executives

Built for boards, CIOs, and audit committees

• Executive Brief

A non-technical overview of the NHI governance gap and how Arkion closes it. Built to forward to your board.

• Compliance Crosswalk

DORA, NIS2, ISO 27001:2022, SEC Cyber-Disclosure — mapped to exactly which Arkion capability satisfies each control.

• Cost of Inaction

Translate NHI exposure into dollars. The cost of a credential-related breach measured against the cost of governing one.

• Trust Center· soon

Security architecture, sub-processors, DPA / MSA / BAA templates, attestation roadmap. Built for procurement.

Learn

Field notes, principles, and the Standard

• The NHIG Standard

Version 1.0 of the Non-Human Identity Governance Standard. Principles, vocabulary, maturity model. Open for comment.

• Field Notes

Regulatory updates, principle additions to the Standard, breach post-mortems. Slow, considered writing from inside the category.

• AI Agent Governance

What it means to govern an AI agent's identity — provisioning, scoping, revoking. Topic explainer.

• Certificate Lifecycle

From issuance through rotation to revocation. The cryptographic primitives Arkion is built on.

• Identity Registry

The single system of record for every non-human identity in your enterprise.

• Why Now

DORA. NIS2. SEC Cyber-Disclosure. The 2024–2026 timeline that turned NHI governance from optional to required.

Tools

Estimate, scan, and act

• Risk Estimator

Two minutes. Seven questions. A directional estimate of how many non-human identities are operating outside any governance boundary.

• Discovery Scan

A read-only scan of one environment. Every NHI found, named, scored. Delivered to your inbox. No agents installed.

• Implementation Timeline

Day 1 scan. Week 1 findings call. Week 2–3 pilot. Week 4 governed estate. The path from first call to first audit answer.

About the Role

We are looking for a Backend Software Engineer with strong Rust expertise to build secure, scalable, and high-performance services for our Next-Gen Human Identity (NHI) Platform.

You will play a key role in designing and implementing backend services, APIs, and cryptographic workflows, working closely with the Software Architect, Frontend Engineer, and Cloud & Deployment Engineer.

This role requires someone who is both strong in systems programming and backend development, and comfortable working on security-focused systems (TLS, certificates, identity).

Responsibilities

What you’ll own.

• Design and build high-performance backend services in Rust.
• Develop REST/gRPC APIs for certificate management, identity workflows, and system operations.
• Implement asynchronous and concurrent systems using Rust best practices.
• Write clean, maintainable, and testable code.

Security & cryptography

• Work with TLS/SSL, X.509 certificates, and secure communication flows.
• Implement or integrate certificate lifecycle management (issuance, rotation, revocation).
• Ensure secure handling of keys, secrets, and authentication flows (mTLS, token-based).

Cloud-native & distributed systems

• Build services designed for containerized environments (Docker).
• Work with Kubernetes-based deployments.
• Collaborate on scalability, observability, and reliability.
• Integrate with cloud services (AWS, Azure, or GCP).

Data & persistence

• Design and implement PostgreSQL schemas.
• Optimize queries and ensure performance at scale.
• Handle transactional workflows and consistency.

Collaboration

• Work closely with the Software Architect on system design.
• Partner with the Frontend Engineer on API contracts.
• Partner with the Cloud Engineer on deployment and runtime concerns.
• Contribute to technical discussions and design decisions.

Required Skills

What you’ll bring day one.

Core backend & Rust

• 3 to 6 years of backend development experience.
• Strong proficiency in Rust.
• Experience with async programming (tokio, async/await).
• Experience with Rust web frameworks (Axum, Actix, Warp).
• Solid understanding of ownership, concurrency, and memory safety.

API & systems design

• Experience building RESTful or gRPC APIs.
• Understanding of microservices architecture.
• Ability to design clean, versioned APIs.

Database

• Strong experience with PostgreSQL.
• Knowledge of indexing, query optimization, and schema design.

Cloud & DevOps awareness

• Experience with Docker and Kubernetes basics.
• Familiarity with CI/CD pipelines.

Security awareness

• Understanding of TLS/SSL fundamentals.
• Secure coding practices.
• Experience with certificate management is a strong plus.

Nice to Have

• PKI systems, certificate authorities, ACME protocol.
• KMS / HSM integrations.
• Identity & access management systems.
• Next.js frontend integration exposure.
• Experience in security or infrastructure platforms.
