We are seeking anExperienced Quantum Compiler Engineerfor ourBroomfield, COlocation.

Our compiler team is at the forefront of bridging the gap between groundbreaking quantum applications and the unparalleled computing power of quantum machines. As a Quantum Compiler Engineer, you are invited to join an interdisciplinary team of physicists and software developers dedicated to transforming platform agnostic quantum algorithms into concrete, executable instructions tailored for our state-of-the-art trapped-ion quantum computers.

In this role, you will engage in pioneering work, collaborating closely with compiler specialists to forge user-friendly languages and tools designed for crafting quantum programs. Your expertise will be instrumental in advancing the development of sophisticated heuristics and algorithms. These innovations are critical for optimizing the routing of ions across complex topologies, significantly enhancing the speed and efficiency of quantum applications executed on our platforms.

By contributing to our team, you will not only play a key role in optimizing code generation for quantum computing but also in shaping the future of quantum technology. Your work will ensure that our quantum computers can realize their full potential, unlocking new possibilities for solving some of the world's most challenging problems.

Key Responsibilities:

  • Design and develop compiler front-end (quantum languages), back-end (machine-specific targeting), and optimization (quantum circuit optimization and classical optimization) passes operating on both classical and quantum operations
  • Benchmark, profile, and iteratively improve the execution performance of our compiler and the quality and performance of quantum programs aligned to current and future architectures
  • Collaborate on the design and implementation of a compiler targeting a real-time, distributed execution environment
  • Work with a diverse team including physicists and other engineering disciplines to solve complex problems
  • Create high quality code in an R&D and rapid prototyping environment

YOU MUST HAVE:

  • Bachelors Degree minimum
  • Minimum 1+ years of industry or post-graduate experience in an engineering, lab, or R&D environment
  • Minimum 2+ years of experience developing for quantum compilers and/or quantum algorithms
  • Minimum 3+ years of programming experience with Python, Rust, C++, or similar language
  • Due to Contractual requirements, must be a U.S. Person. defined as, U.S. citizen permanent resident or green card holder, workers granted asylum or refugee status
  • Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.

WE VALUE:

  • Masters/PhD degree in Computer Science
  • Strong understanding of compiler design fundamentals
  • Ability to understand, combine, and apply algorithms to solve complex problems
  • Ability to solve complex problems and ability to communicate how you did it
  • Track-record of using python or other rapid prototyping and development tools to solve complex challenges
  • Rust development experience especially including any LLVM or optimization algorithm development
  • Demonstrated ability to work with a variety of algorithms, including tree, graph, SAT, and, at times Machine Learning and other algorithms
  • History of working with and developing for the LLVM toolchain
  • Experience with LLVM IR and MLIR
  • Experience with development of application-specific algorithms, especially where exact/optimal solutions are computationally intractable
  • Proficiency with software testing and deployment tools
Compensation & Benefits:
Non-Incentive Eligible
Estimated Salary Wage: $97,000 - $122,000 Annually
What is in it for you?
-A competitive salary and innovative, game-changing work
-Flexible work schedule
-Employer subsidized health, dental, and vision insurance
-401(k) match for student loan repayment benefit
-Equity, 401k retirement savings plan + 12 Paid holidays and generous vacation + sick time
-Paid parental leave
-Employee discounts

What Hiring Managers Look for First in Quantum Computing Job Applications (UK Guide)

Quantum computing is one of the fastest-evolving fields in technology, blending physics, mathematics, computer science and engineering. Roles in this space — from Quantum Algorithm Developer and Quantum Software Engineer to Quantum Research Scientist and Quantum Hardware Specialist — are highly sought after, and hiring managers are exceptionally selective. Because quantum computing is complex and multidisciplinary, recruiters and hiring managers look for clear, concrete evidence of relevant expertise and impact right at the start of your application. They often decide whether to read your CV in detail within the first 10–20 seconds, based on a handful of high-value signals. This guide breaks down exactly what hiring managers look for first in quantum computing applications, how they assess CVs and portfolios, and what you can do to optimise your application to get noticed in the UK quantum job market.

Riverlane Jobs in Quantum Computing: UK Guide for Job Seekers (2026)

If you’re looking for Riverlane jobs in quantum computing, you’re aiming at one of the most important layers in the quantum stack: quantum error correction (QEC). In simple terms, Riverlane focuses on the software, methods & tooling that help quantum computers produce reliable results despite noise. That matters because as quantum hardware scales, the ability to correct errors becomes the difference between “interesting experiments” and “useful quantum computing”. This guide is written for UK job seekers who want to understand: what Riverlane does (in job-seeker language) the roles they hire for the skills that map best to their work how to tailor your CV & LinkedIn how to prepare for interviews how to find & land Riverlane vacancies in the UK You do not need to be a quantum PhD to have a realistic pathway in. But you do need to understand the problem they’re solving & position your experience around it.

The Skills Gap in Quantum Computing Jobs: What Universities Aren’t Teaching

Quantum computing stands at the frontier of technological innovation. Promising breakthroughs in areas as diverse as cryptography, materials discovery, optimisation and machine learning, quantum technologies are shifting from academic research to early commercial deployment. Governments, defence organisations, finance firms and tech innovators around the world — including in the UK — are investing heavily in quantum talent and capability. Yet despite this surge in interest and investment, employers consistently report a troubling trend: Many graduates with quantum computing qualifications are not prepared for real-world quantum computing jobs. This isn’t a reflection on students’ intelligence or effort. Rather, it reveals a persistent skills gap between what universities teach and what organisations actually need. In this article, we’ll explore that gap in depth — what universities do well, where programmes fall short, why the divide persists, what employers actually want, and how jobseekers can bridge that gap to build successful careers in quantum computing.
