Freelance Compiler Software Engineer information

What are the key skills and qualifications needed to thrive as a Freelance Compiler Software Engineer, and why are they important?

To thrive as a Freelance Compiler Software Engineer, you need a deep understanding of compiler theory, programming languages (such as C/C++ or Rust), and data structures, often supported by a degree in computer science or related experience. Proficiency with tools like LLVM, GCC, build systems, and debuggers, as well as familiarity with version control systems like Git, is typically required. Strong problem-solving, self-management, and communication skills help you deliver solutions to clients and collaborate remotely. These skills and qualities are crucial for building efficient, reliable compiler software and maintaining client trust in a competitive freelance environment.

What is the difference between Freelance Compiler Software Engineer vs Freelance Software Developer?

AspectFreelance Compiler Software Engineer

Required CredentialsTypically a computer science degree or equivalent experience, knowledge of compiler design, programming languages, and software development tools.
Work EnvironmentIndependent, project-based work often involving specialized tasks like language parsing, optimization, and code generation.
Employer & Industry UsageUsed by tech companies, startups, or clients needing custom compiler solutions or language tools.
Common Search & ComparisonOften compared with general software developers but focuses on compiler-specific expertise.

While both roles involve software development, a Freelance Compiler Software Engineer specializes in designing and optimizing compilers and language tools, requiring specialized knowledge. In contrast, a Freelance Software Developer has a broader scope, working on various applications and systems without necessarily focusing on compiler technology.

What are some common challenges faced by freelance compiler software engineers when working with clients on diverse projects?

Freelance compiler software engineers often encounter challenges such as adapting quickly to different codebases, understanding varying project requirements, and integrating their work with existing developer teams. Since compiler projects can be highly specialized, clear communication with clients about technical constraints and expectations is crucial. Additionally, freelancers may need to juggle multiple projects simultaneously, which requires strong organizational skills and the ability to prioritize tasks effectively.

What is a Freelance Compiler Software Engineer?

A Freelance Compiler Software Engineer is a professional who specializes in designing, developing, and optimizing compilers on a contract or project basis rather than as a full-time employee. They work with programming languages and toolchains to translate source code into executable programs, ensuring efficiency and correctness. These engineers may be hired for projects such as building custom compilers, improving existing compiler performance, or integrating new language features. Freelancers enjoy flexibility in choosing projects and often work remotely for clients across various industries.

Senior Software Engineer, Back-end (Compiler)

Q-CTRL

San Francisco, CA • On-site

$135K - $210K/yr

Full-time

Posted 11 days ago

Job description

About the team
At Q-CTRL, Quantum Computing Engineering is a global team of software engineers and infrastructure experts,combining deep technical expertise with a startup mindset to deliver real impact through software innovation. Our work is underpinned by robust standards, and by embracing the three virtues. Our team excels in areas across back-end, front-end, machine learning, and platform engineering.
 
We transform Q-CTRL's world-leading technological breakthroughs into commercial software products with applications across defense, research, and industry. We work closely with Product, Design, and Research teams to accelerate the path to quantum advantage worldwide.
What you'll be doing:
  • Build the backbone of quantum tech: Design, develop, and optimize scalable backend services in Python.
  • Own the compiler stack: Maintain and evolve the compiler that translates OpenQASM3 + OpenPulse programs into low-level controller instructions.
  • Bridge research and engineering: Work closely with world-class researchers and quantum engineers, translating experimental needs into production-ready code and debugging real-world execution challenges.
  • Experiment on quantum hardware: Get hands-on with QPUs, validating compiler output and controller behaviors through real device experiments.
  • Engineer for performance: Deliver high-efficiency service-to-service communication using modern protocols (gRPC, GraphQL, REST).
  • Shape the future stack: Help define the software practices, tools, and design patterns that will power the next generation of quantum control systems.
  • Other duties within the Employee's skills and experience, or with reasonable training.
Ideally you'll have:
  • Bachelor's degree in Computer Science, Engineering, or related field.
  • 5+ years of backend software development experience with Python.
  • Experience with quantum hardware control systems (or similar) or pulse-level programming (e.g., OpenQASM3, Qiskit Pulse, Qua).
  • Familiarity with popular Python web frameworks (Django, Flask, FastAPI).
It would be fantastic (but not essential) if you bring:
  • Familiarity with formal language design (e.g. LL(*) or PEG parsers) and compiler theory or ecosystems (e.g. LLVM/MLIR).
  • Experience with implementing Python extension modules with systems programming languages such as C++ or Rust for accelerating Python programs.
  • Knowledge or exposure to adjacent technologies such as FPGA programming, low-latency or real-time systems.

Salary
The base salary for this position is targeted between $135,000 - $210,000 and will ultimately be determined by specific job-related skills, experience, level, location and other contributing factors. Depending on the position offered, this role may be eligible for annual discretionary bonuses, equity and other forms of compensation outside of the targeted range. For more information on benefits at Q-CTRL, please visit our careers page at https://q-ctrl.com/careers.

Should you have any questions related to the compensation package, please speak directly with the Talent Acquisition representative.


About Q-CTRL
Q-CTRL is the global leader in AI-powered quantum control infrastructure software. We build the tools that make quantum technology useful, solving the hardest challenges in quantum computing and quantum sensing to deliver real-world impact.
 
Founded in 2017, we operate globally with offices in Sydney, Los Angeles, San Francisco, Berlin, and Oxford. Our teams bring together technical and multi-disciplinary expertise across the product lifecycle, and we're hiring talent to help scale every part of the business. We work quickly to turn cutting-edge science into deployable technology.
 
In 2024 we raised US$113 million in Series B funding, the largest aggregate investment for a quantum software company. Six months later we delivered the first commercial quantum advantage with Ironstone Opal, our field-validated quantum navigation solution for defense and industry.
 
At Q-CTRL, we prioritize outcomes over hours. We offer flexibility, equity potential, and competitive benefits that reflect our high-performance culture. If you're ready to help shape the future of quantum, we'd love to hear from you!
 
Qualified applications with arrest or conviction records will be considered for employment in accordance with the Los Angeles County Fair Chance Ordinance for Employers and the California Fair Chance Act.
 
Please be advised that our communications will only come from the @q-ctrl.com domain. All our active job postings are available on our company website.
 
To recruitment agencies, we do not accept unsolicited branded profiles and are not responsible for any fees related to unsolicited resumes.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
