Web3 Security Sysadmin Jobs in United States, North America

Tempo is a layer-1 blockchain purpose-built for stablecoins and real-world payments, born from Stripe’s experience in global payments and Paradigm’s expertise in crypto tech.

Tempo’s payment-first design provides a scalable, low-cost predictable backbone that meets the needs of high-volume payment use cases. Our goal is to move money reliably, cheaply, and at scale. Our north star is simplicity for users: fintechs, traditional banks, merchants, platforms, and anyone else looking to move their payments into the 21st century.

We're building Tempo with design partners who are global leaders in AI, e-commerce, and financial services: Anthropic, Coupang, Deutsche Bank, DoorDash, Mercury, Nubank, OpenAI, Revolut, Shopify, Standard Chartered, Visa, and more.

We’re a team of crypto-optimists, building the infrastructure needed to bring real, substantial economic flows onchain. We like to move fast and swing for the fences — join us!

The Role

You'll own and build Tempo's corporate IT infrastructure — identity, device management, endpoint security, and the automation that ties it all together. This is a hands-on engineering role, not a help desk seat. You'll bring software-engineering rigor to IT systems and help secure a company operating at the frontier of crypto.

Responsibilities

• Architect and automate the full identity lifecycle — HRIS → Okta → SaaS apps — eliminating manual provisioning and off boarding gaps

• Complete and maintain SSO/SCIM integrations across the entire SaaS stack

• Own Jamf Pro end to end: PreStage enrollment, configuration profiles, software updates, certificate distribution

• Deploy and tune endpoint security (SentinelOne) — policy management, MDM-driven deployment, alert triage

• Expand SIEM coverage and write detection/alerting rules with a detection-as-code approach

• Build toward infrastructure-as-code management of all IT tooling (Terraform, GitHub Actions)

• Resolve hard identity, device, and access escalations that get past first-line support

• Drive SOC 2 readiness — unified audit trails across identity, device, and security systems

Qualifications

• 4+ years in IT engineering roles

• Hands-on Okta administration: SSO, SCIM, SAML/OIDC integrations, lifecycle policies, Okta Workflows. Understands HRIS-as-source-of-truth (Rippling or similar)

• Production Jamf Pro experience: PreStage enrollment, configuration profiles, software update management, certificate distribution. macOS-first

• Deployed and operated an EDR platform (SentinelOne or comparable) — policy tuning, MDM deployment, alert triage

• Strong scripting (Python/Bash/Go preferred), comfortable with REST APIs, webhooks, JSON, auth flows, and event-driven workflows

• Git-based config management, CI/CD pipelines (GitHub Actions), Terraform or equivalent

• Solid grasp of DNS, certificates/PKI, ZTNA (Tailscale or similar), and modern access control models

Nice-to-Haves

• Crypto/blockchain security exposure — multisig/hardware-wallet workflows (Fireblocks or similar), phishing/lookalike-domain campaigns, high-value signer threat models

• Detection-as-code: SIEM detections as version-controlled rules (Panther Python models, Sigma, or equivalent)

• Apple platform depth beyond basic Jamf — DDM, MDM protocol internals, notarization/signing/packaging, macOS security frameworks (TCC, system extensions)

• Mapped controls to SOC 2, ISO 27001, NIST CSF, or CIS — understands what audit-ready evidence looks like

• Built Slack-driven workflows, bots, or self-service internal tooling

• Public open-source contributions to IT/security tooling
