The Opportunity
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
How You’ll Make a Difference Day to Day
- 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.
Minimum Qualifications
- 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
Preferred Qualifications
- 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)
