About Iru

Iru is the AI-powered security & IT platform used by the world’s fastest-growing companies to secure their users, apps, and devices. Built for the AI era, Iru unifies identity & access, endpoint security & management, and compliance automation—collapsing the stack and giving IT & security time and control back.

Iru is backed by some of the smartest investors in tech—General Catalyst, Tiger Global, Felicis, Greycroft, and First Round Capital. In July 2024, Iru raised $100 million from General Catalyst, valuing the company at $850 million. Customers include Notion, Cursor, Lovable, Replit, and Mercor, and Iru partners with industry leaders such as ServiceNow and AWS. Iru was named to Forbes’ America’s Best Startup Employers 2025 list for employee engagement and satisfaction.

As a Senior Software Engineer on Iru’s Identity product, you’ll join a small, high-ownership team building a brand-new product approaching General Availability (GA). You’ll help shape the architecture and core systems behind a unique runtime environment, focusing on reliability, security, and scalability.

This is a role for engineers who can operate with independence, think from first principles, and go deep—especially in backend systems and databases

Build core product systems: Design and implement backend services and end-to-end flows that power the Identity product.

Go deep on data + SQL: Ability to design correct, performant, and maintainable Raw SQL.

Engineer for reliability and security: Build systems with strong execution guarantees, resilience, and clear operational behavior—especially in a constrained, low-level runtime.

Own critical architecture decisions: Evaluate tradeoffs, document reasoning, and choose solutions based on requirements—not tool trends.

Operate with high autonomy: Identify what needs to be built, propose approaches, and execute with minimal hand-holding.

Use AI responsibly: Leverage AI tools where helpful, while demonstrating the depth to review, validate, and correct AI-generated code.

Raise the bar through collaboration: Participate in code reviews and technical discussions with a focus on clarity, quality, and long-term maintainability.

5+ years of professional software engineering experience (or equivalent depth)

Strong backend engineering experience building cloud-oriented, server-side systems

Demonstrated experience with SQL and relational databases (Postgres/MySQL or similar), including writing non-trivial queries in production environments

Experience with server-side concurrency / multi-threading and the realities of production systems (performance, failure modes, debugging)

Proficiency in at least one compiled language (e.g., Go, Java, C#, or similar)

Proven ability to work independently, take ownership, and drive projects from concept to delivery

Strong engineering judgment: requirements-first problem solving and clear articulation of tradeoffs

Comfortable working in an environment with limited “black boxes” and high responsibility for core flows

Ability to work onsite in Miami Tuesday through Thursday as part of our hybrid schedule

Full-stack experience (with a backend/data emphasis); React experience is a plus

Experience designing or supporting systems with high correctness requirements (e.g., idempotency, guaranteed execution, fintech/payments-like constraints)

Identity/security domain experience (authN/authZ, access control, secure system design)

Experience at smaller or high-growth teams where engineers own large portions of the stack

Infrastructure or performance experience paired with a product delivery mindset

Familiarity with AWS and operational best practices (monitoring, logging, incident response)
