# Senior Software Infrastructure Engineer at Ultra

- **Company:** Ultra
- **Location:** Brooklyn, NY
- **Compensation:** $160k–$250k
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2026-08-28
- **Last confirmed live:** 2026-09-05
- **Apply:** https://jobs.gem.com/ultra/am9icG9zdDoXAZrFog9hru15AsdeyrV5

## Job description

## 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)

## About Ultra

## Company Overview
- **One-liner**: Ultra builds practical, general-purpose industrial AI robots that automate repetitive warehouse tasks like packing, sorting, and kitting, with zero integration and rapid deployment.
- **Entity Type**: Private (Seed stage; $625K total funding)
- **Headquarters**: New York, NY, United States
- **Founded**: 2024
- **Founders**: Jon Miller Schwartz (CEO), Max Friefeld (COO), Chetan Parthiban (Co-Founder & Chief Scientist), Oliver Ortlieb (Co-Founder & CTO)

## Core Business
- **Primary industry**: Robotics Engineering / Industrial Automation
- **Target customers**: B2B – warehouses, fulfillment centers, and logistics operators (enterprise and SMB)
- **Mission or purpose**: To deploy practical, general-purpose robots that generate immediate ROI by handling repetitive, high‑volume work, and to scale intelligence through real‑world data.

## Products & Services
- **[Operator](https://www.ultra.tech/)**: A stationary industrial AI robot designed for e‑commerce order packaging, sorting, and kitting. It operates up to 24 hours a day, requires no fixed infrastructure, installs in hours, and covers a 5×5 ft footprint with a 10 ft vertical reach. The robot learns new tasks from example data and improves fleet‑wide as more units are deployed.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of $625K (Seed: $125K in Aug 2024; Pre‑Seed: $500K in Sep 2024 led by Y Combinator)
- **Notable Investors/Partners**: Y Combinator (lead investor), three additional investors in Pre‑Seed round
- **Growth Signals**: 14 total employees (as of early 2025), 19 employees (latest) – **333% YoY headcount growth**; robots already deployed in real warehouses generating revenue and data; launched the Operator robot in April 2026 with 184 LinkedIn reactions; actively hiring across engineering, research, deployment, and people operations.

## Competitive Advantages
- **Zero‑integration deployment**: Robots can be rolled in, plugged in, and turned on within hours – no expensive infrastructure or lengthy integration.
- **Stationary, safe design**: No tipping risk, no battery swaps, no charging breaks – designed for continuous operation in real warehouse conditions.
- **AI trained with examples**: Uses neural nets trained on teleoperation data (≈2 hours) to learn new tasks, enabling rapid adaptation to variable items and changing workflows.
- **Fleet learning**: Every deployed robot feeds data back to improve the entire fleet – a data‑scale moat that compounds with more deployments.

## Strategic Focus
- Rapidly scale deployments across the US in 2025‑2026, building on proven field traction.
- Continue improving robot foundation models for faster, more robust task learning and execution.
- Expand from e‑commerce packaging into adjacent warehouse workflows (e.g., kitting, returns).
- Grow the team (targeting engineering, research, deployment, and people functions) to support production scaling.

## Why Work Here
- **Early‑stage impact**: Join a YC‑backed startup founded by three‑time entrepreneurs (previously founded Layer By Layer, Voodoo Manufacturing) with a decade of collaboration.
- **Fast‑paced, hands‑on culture**: Engineers and researchers directly own firmware, hardware, ML models, and deployment – from design to field support.
- **Real‑world robotics**: Work on robots that are already generating revenue in customer warehouses, not just lab prototypes.
- **Growth trajectory**: 333% headcount growth in the past year, with ambitious plans to scale from 19 to hundreds of employees.
- **Location & flexibility**: Based in New York City; roles span HQ (assembly, testing, R&D) and field deployment across the US.
- **Open roles** (as of early 2026): Robotics Firmware Engineer, Robotics Hardware Engineer, Data Operations Lead, Research Scientist, Product Engineer, Deployment Engineer, Head of People – offering broad ownership and career growth.
