Contract Opt Visa information

What is a Contract OPT Visa?

A Contract OPT Visa refers to employment under the Optional Practical Training (OPT) program for international students in the U.S. on an F-1 visa. OPT allows these students to work temporarily in their field of study, and 'contract' typically means they are hired for a specific period or project, rather than a permanent position. OPT participants must have an Employment Authorization Document (EAD) and can work for various employers, including through short-term contracts. This opportunity helps students gain practical experience related to their academic major. Employers and students must ensure compliance with all OPT regulations during the contract period.

What are the key skills and qualifications needed to thrive as a Contract OPT Visa holder?

To thrive as a contract worker on an OPT Visa, you typically need a relevant degree in your field of study, strong technical expertise, and eligibility for OPT authorization. Familiarity with specialized software, project management tools, and understanding of compliance with visa regulations are essential. Excellent communication, adaptability, and networking skills help you build relationships and navigate the challenges of short-term roles. These skills and qualifications are crucial to securing and excelling in contract positions while maintaining legal work status in the U.S.

What are some typical challenges faced by Contract OPT Visa holders in the workplace, and how can they be addressed?

Contract Opt Visa holders often encounter challenges such as navigating complex immigration paperwork, adapting quickly to new workplace cultures, and managing timelines for visa extensions. To address these, it's helpful to maintain close communication with HR and legal teams regarding visa status, proactively seek feedback for faster onboarding, and connect with employee resource groups for support. Staying organized and informed can help reduce stress and ensure compliance with all visa requirements.

What is the difference between Contract Opt Visa vs Contract Software Developer?

AspectContract Opt VisaContract Software Developer
CredentialsF-1 visa status, OPT approvalRelevant programming skills, possibly a degree in CS or related field
Work EnvironmentTemporary employment, often in tech or corporate sectorsProject-based, tech companies, startups, or corporate IT teams
Employer & Industry UsageEmployers hiring international students for temporary rolesEmployers seeking software development talent on a contract basis

The Contract Opt Visa is a temporary work authorization for international students on OPT, allowing them to work in the U.S. in their field of study. Contract Software Developers are hired for specific projects, often under contract agreements. While both roles involve temporary employment in the tech industry, the Contract Opt Visa pertains to visa status and work authorization, whereas Contract Software Developer refers to the job position itself.

Job description

AI Biologist - SpatialBench-Long

As molecular data generation and frontier model intelligence grows, new approaches to data analysis are needed across the biotech industry. Latch is building intelligent, high-performance agents for biological data analysis, empowering over 5,000 scientists across 150+ R&D labs to handle data from instrument-to-insights.

We're seeking a Bioinformatics Engineer to join our Spatial team, working at the frontier of what artificial intelligence can achieve in biology.

About the Role

You design tasks that test whether AI agents can work through real spatial transcriptomics projects. It's not about whether they can run a tool, it's whether they understand how decisions cascade. You pick how to align tissue images, which affects how you segment cell boundaries, which determines which unmixing method works, which shapes everything downstream. We're testing if they get that ripple effect. You'd be pulling from real published papers, building multi-stage tasks, and grading whether agents understand the why behind each choice, not just the mechanics.

Requirements

  • Systems thinking across spatial workflows: You understand how image preprocessing (tissue alignment, background removal) affects segmentation quality; why nucleus-level segmentation demands different deconvolution (RCTD, Tangram, SPOTlight, STRIDE) than spot-level data; when morphological features matter for downstream inference

  • Domain-specific judgment: You know the trade-offs between platforms (Visium's spots vs. MERFISH's near-cellular resolution vs. Xenium's high-plex imaging); when to deconvolve spots vs. when to segment first; how cell density and tissue morphology constrain method choice

  • Tool flexibility: You learn spatial tools (Baysor, STdeconvolve, giotto, Squidpy) and image-processing pipelines as needed

  • Task design: You build multi-checkpoint benchmarks where agents must handle registration failures, justify segmentation thresholds, and defend deconvolution assumptions in tissues with variable morphology

Culture @ LatchHow we work.

Genuinely flexible schedules, we just ask that you communicate when you're coming in later than usual. We care most about hard work and output. We're respectfully opinionated, it will always be us against problems, not each other. Optimize for each other's time and bring solutions, not just problems. You'll join a bench suited to your expertise, but we value cross-domain learning and interoperability across teams.

The office & perks.

Waterfront office near Oracle Park, 2x free daily meals, unlimited snacks, company outings most months, and team offsites. Plus a vibrant team: cycling, soccer, figure skating, boxing, run clubs, reading clubs, martial arts, music, game nights.

Compensation & Logistics

  • 1099 (or W8-BEN) contract, 40 hrs/week, no end date

  • Fully performance-based pay: $120K–$180K, uncapped upside. 2x quota = 2x pay.

  • 2-4 week paid ramp - full OTE from day one

  • Remote (globally), hybrid, or onsite in SF (onsite preferred)

  • Work authorization: OPT visa holders only (not STEM Extension)

  • Onsite perks: 2x free meals/day, waterfront office (China Basin), monthly parking (based on availability)

  • Candidates with all of the above qualifications + proven management skills will be eligible for more senior positions

We move fast: 8–12 days from submission to offer.
