ROLE
Junior Software Engineer (Trading Systems & OS)
Location: Chicago, IL (Loop)
Team: Proprietary Trading Group
Geneva Trading is seeking a Junior Software Engineer with a systems-programming pedigree to join our Chicago headquarters. In this role, you will be an integral part of a specialized development staff that works side-by-side with Traders and Quantitative Researchers. We aren't looking for a "back-office" developer; we need a problem solver who wants to sit at the intersection of code and the markets. You will use your understanding of Operating Systems and low-level architecture to ensure our strategies are the fastest and most reliable in the world. This role is for the curious mind—the engineer who doesn’t just want to write a strategy but wants to understand exactly how the Linux kernel handles every packet that strategy sends.
Core Responsibilities
-
Collaborative Development: Work daily within a tight-knit unit of Traders and Quants to translate high-frequency strategies into production-ready code.
-
Systems-Level Optimization: Build and tune trading applications using Modern C++, with a heavy focus on OS-level performance (e.g., CPU affinity, memory management, and kernel bypass).
-
Research & Diagnostic Tooling: Leverage Python to build high-speed data pipelines, backtesting frameworks, and real-time monitoring tools to analyze strategy behavior.
-
Deep-Dive Problem Solving: Act as the "systems expert" for the desk—diagnosing jitter, race conditions, or latency spikes by digging into the Linux stack (schedulers, interrupts, and syscalls).
-
Execution Excellence: Maintain a "zero-error" mindset, ensuring the absolute correctness of trading logic in a high-stakes, real-time environment.
THE TECHNICAL PROFILE
-
Education: BS/MS in Computer Science or Computer Engineering with a strong academic focus on Operating Systems.
-
Language Proficiency:
- C++: Professional-level understanding of pointers, memory layout, and concurrency.
- Python: Ability to write clean, efficient code for data analysis and automation.
- OS Fundamentals: Deep knowledge of Linux/Unix internals. You should understand how the OS manages hardware resources and how to optimize that interaction for speed.
- The "Curious" Mindset: A natural drive to deconstruct complex systems. You are the person who reads the man pages and enjoys figuring out the "why" behind a system's behavior.
THE GENEVA ENVIRONMENT
-
High-Touch Collaboration: You are part of the trading desk’s heartbeat, where feedback loops between code and market impact are measured in microseconds.
-
Intellectual Rigor: Solve non-trivial puzzles alongside some of the brightest minds in the industry.
-
Chicago Culture: Work in our state-of-the-art Chicago office, enjoying the energy of the trading floor combined with a flat, meritocratic structure.
COMPENSATION
- Base Salary Range: $80,000 – $130,000, plus eligibility for a performance-based bonus.
Final compensation will be determined based on the candidate’s skills, experience, education, and qualifications. In addition to base salary, Geneva Trading offers a competitive total rewards package, including a comprehensive benefits program.
Application expected to close on 5/15/26.
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

How to Get Visa Sponsorship as a Junior Software Developer
Target companies with active STEM OPT hiring pipelines
Mid-size tech companies and startups often hire OPT students more readily than large enterprises with rigid HR processes. Look for employers who have previously hired F-1 students, as they already understand STEM OPT extension requirements and timelines.
Apply before your OPT start date, not after
Most employers want a candidate ready to start within two to four weeks. Applying three to four months before graduation gives you time to interview, receive an offer, and begin work within your authorized OPT window without causing unnecessary delays for the hiring team.
Emphasize your STEM OPT extension eligibility upfront
STEM-eligible degrees give employers up to three years before needing to file an H-1B. Lead with this in cover letters and recruiter conversations. It meaningfully reduces the employer's perceived risk and positions OPT as less of a burden than they may expect.
Frame your authorization period around the H-1B lottery cycle
STEM OPT gives employers three H-1B lottery chances. Mention this explicitly when employers raise visa concerns. Three attempts at a 25 to 30 percent selection rate substantially improves the odds, and most hiring managers are unaware of this without someone explaining it clearly.
Prioritize roles that require a CS or engineering degree specifically
Junior developer roles that list a computer science or software engineering degree as a hard requirement align cleanly with specialty occupation criteria. These positions support both your OPT authorization now and a straightforward H-1B petition later if your employer pursues sponsorship.
Report your employment to your DSO within 10 days of starting
Once you accept an offer and begin working, update your SEVIS record through your Designated School Official immediately. Failure to report employer details within 10 days is an OPT compliance violation that can jeopardize your status regardless of your work authorization approval.

Get Access To All JobsFrequently Asked Questions
Can I work as a Junior Software Developer on OPT without any restrictions?
Yes, but your work must be directly related to your degree field. A CS or software engineering degree maps cleanly to Junior Software Developer roles. Positions in unrelated fields, such as general sales or administrative support, would not qualify as valid OPT employment. Your DSO can confirm whether a specific role aligns with your degree program.
Do Junior Software Developer jobs qualify for the STEM OPT 24-month extension?
They do in most cases. If your degree is in computer science, software engineering, information technology, or another STEM-designated field, you can apply for a 24-month STEM OPT extension after your initial 12-month OPT period. Your employer must be E-Verify enrolled and agree to a formal training plan using Form I-983. This gives you up to 36 months of OPT authorization total.
What happens to my OPT if I lose my Junior Software Developer job?
You have a cumulative 90-day unemployment limit during standard OPT, which extends to 150 days if you receive a STEM extension. The clock starts from your OPT start date, not from when you lose a job. Exceeding these limits terminates your F-1 status. Finding a new qualifying role as quickly as possible is critical. Migrate Mate is a good place to search for OPT-eligible developer roles quickly.
Can I work for a startup or small company on OPT as a Junior Software Developer?
Yes, any employer can hire you on standard OPT regardless of company size. For STEM OPT extensions, the employer must be enrolled in E-Verify, which most registered businesses can complete. Startups that are not yet E-Verify enrolled can register before your extension period begins. Confirm E-Verify status before signing an offer if you are planning to apply for the STEM extension.
How do employers typically view OPT candidates for Junior Software Developer roles?
Most tech employers familiar with hiring international talent view OPT candidates favorably, especially for STEM-eligible roles. The three-year total authorization window gives them multiple H-1B lottery cycles before needing to make a long-term sponsorship decision. Employers unfamiliar with OPT often overestimate the complexity. Browsing companies that actively post on Migrate Mate is an efficient way to identify employers already comfortable hiring OPT students.
