Overview

Ultra is looking for a

Senior Software Infrastructure Engineer

to design and implement industry standard company data infrastructure and tooling, along with airtight information security and architecture, to enable multiple mission-critical projects for Ultra’s long-term growth. As Senior Infrastructure Engineer, you'll own the company's data infrastructure and information security architecture end to end: auditing what exists today, closing the gap to industry-standard practice within six months, and building the authZ/authN foundation that makes AI tooling and enterprise customers trust us with their data. You'll also own the platform that lets engineers and vibe-coders across Ultra get safe, compliant data access without waiting on you for every request. This is an in-person NYC role with direct line of sight to top-line business goals.

Who You Are

• You have 7+ years in infrastructure/security engineering, with real ownership of authn/authz systems in production


• You're proficient in Python; a software generalist who knows when to build vs. buy


• You’ve led or heavily contributed to a SOC2 (or equivalent) compliance effort — you know what auditors actually look for


• You're comfortable auditing legacy systems and making the call on what to fix, replace, or leave alone


• You have experience designing data infrastructure that scales to onboard new data sources without re-architecting each time


• You're dangerous with LLMs because you know when they're wrong; you've thought hard about misbehaving agents and what it takes to secure AI tooling


• You can look at a backlog of "we need access to X" requests and pick the highest-leverage platform investment


• You have a bias toward shipping durable systems over quick patches; you document decisions so others can build on them

What You’ll Do

• Audit existing authn/authz infrastructure and produce a gap analysis against industry standards


• Design and execute a roadmap to bring infrastructure to industry-standard within 6 months


• Drive SOC2 compliance workstream — controls, evidence, remediation; turn compliance requirements into enforceable platform controls


• Build scalable systems/tooling for onboarding new data sources


• Design and implement authorization architecture that securely enables AI tooling across the company


• Support software engineers and vibe-coders so everyone can ship code safely and quickly


• Partner with engineering leadership on architecture decisions that support enterprise-market expansion

Bonus Points

• You've built a comprehensive authentication and authorization system at another company


• You have strong opinions about the best way to implement RBAC (and its limitations)
