Security Engineer (Infrastructure Security)

About 1mind

1mind is a platform that deploys multimodal Superhumans for revenue teams. These Superhumans combine a face, a voice, and a GTM brain equipped with deep technical and product knowledge. They can lead unlimited simultaneous conversations 24/7, meet buyers when they’re most active, qualify leads, book meetings, deliver interactive demos, handle objections, uncover pain points, build value models, provide support, and onboard customers across websites, inside your product, in live calls, and deal rooms. Our mission is to redefine how humans and AI collaborate at scale, creating high-impact AI teammates that drive measurable revenue outcomes.

About the Role

You’ll design, implement, and operate security controls across the stack, from physical hardware/firmware and host OS hardening to Kubernetes, networks, CI/CD, and data planes, defending against sophisticated adversaries and insider threats. You’ll partner with platform, backend, and ML/IR teams to raise the security bar for emerging AI workloads and sensitive data (including model artifacts and user data), balancing principled safeguards with product velocity.

Key Responsibilities

• Design and build layered security controls across OS, Kubernetes, networks, identity, and CI/CD to protect high-value assets.

• Drive deployment of security enhancements and policy changes across multi-region infrastructure.

• Lead high-impact initiatives: checkpoint/model artifact protection and encryption, network isolation and segmentation, secrets and machine identity, policy-as-code, and secure storage/access pathways.

• Automate detection, prevention, and response with guardrails and paved paths (IaC modules, validated baselines, admission controls).

• Embed security into developer workflows (shift-left reviews, SAST/DAST/SCA, SBOM, provenance), and instrument robust observability for security signals.

• Partner on risk assessments, threat modeling, and incident response; deliver postmortems and durable mitigations.

• Champion a healthy security culture that enables rapid iteration while meeting reliability, safety, and compliance expectations.

Qualifications

• Deep understanding of security principles, common vulnerabilities, and practical defenses across infra and application layers.

• 5+ years building and operating core infrastructure security or platform security at scale.

• Expertise securing cloud platforms (e.g., AWS/Azure/GCP), including cloud networking, identity, and cloud-agnostic abstractions.

• Experience with datacenter security from construction/bring-up to multi-tenant operations.

• Familiarity with container/Kubernetes security (workload identity, admission controls, policy engines, image supply chain).

• Proven track record delivering scalable, automated security solutions and moving organizations via tooling and paved paths.

• Strong analytical/problem-solving skills; crisp communication with technical and non-technical stakeholders.

• Plus: Service mesh and mTLS, HSM/KMS and envelope encryption, OPA/rego, attestation & provenance, TPM/PKI, confidential computing, GPU/accelerator security, compliance frameworks.

Why Join 1mind

• Secure the foundation behind multimodal Superhumans redefining enterprise GTM and support.

• High-ownership, small team: ship meaningful safeguards used across products and infrastructure.

• Work at the intersection of AI systems, platform engineering, and safety with measurable business impact.

• Global footprint and a culture that prioritizes responsible deployment over unfettered growth.
