Software Engineer - Real time Systems (Rust/C++)
NYC Metro Area
Full-time
Onsite
Senior Level
$200K/yr - $250K/yr
5+ years expUMATR is a highly technical organization focused on building internal-grade infrastructure for validating complex systems. They are seeking a Senior Systems Engineer to build software that behaves consistently in real-time execution environments, working closely with hardware and ensuring system performance under load. The role involves solving complex timing issues and collaborating with engineering teams to maintain system reliability and visibility.

Hiring Manager
Oisin Scanlon
Responsibilities
You’ll be building software that has to behave the same way every time, even under pressure
You’ll spend time shaping how work is scheduled and coordinated across the system, making sure it holds up as load increases and new components are added
You’ll also work closely with other engineering teams to make this behaviour visible and testable, without introducing uncertainty or hidden latency
A big part of the role is digging into hard problems - tracking down where timing starts to drift, understanding why systems behave differently under stress, and putting guardrails in place so those issues don’t come back as the platform grows
Qualification
Required
5+ years of experience in low-level, systems, or embedded software development
Proficiency in C++ or Rust, with an emphasis on predictability and performance
Practical experience working under real-time or timing-constrained execution models
Strong understanding of scheduling, synchronization, and system timing behavior
Comfort working close to hardware and diagnosing performance or correctness issues
Ability to reason precisely about execution order, latency, and system state
Preferred
Experience with simulation, validation, or testing of complex systems
Familiarity with time-sensitive data paths or synchronized components
Background in environments where correctness and determinism are non-negotiable
Benefits
Full range of benefits (medical, dental, vision coverage)
High degree of technical autonomy and ownership
