H-1B1 Singapore Visa Tech Lead Jobs
Tech Lead jobs with H-1B1 Singapore visa sponsorship let you move directly to a U.S. consulate interview without entering any lottery. The annual cap of 5,400 sits well below demand, so Singaporean engineers leading product or platform teams can time their applications around employer hiring cycles rather than lottery registration windows.

Founded in 2017, Obsidian Security was created to close a critical gap: securing the SaaS applications where modern business happens—platforms like Microsoft 365, Salesforce, and hundreds more.
Backed by top investors including Greylock, Norwest Venture Partners, and IVP, we've built a complete SaaS security platform to reduce risk, detect and respond to threats, and prevent breaches at the source. Our team includes leaders who helped define the categories of endpoint and identity security at CrowdStrike, Okta, Cylance, and Carbon Black.
Now, we're transforming how SaaS is secured—in the era of agentic AI.
Today, Obsidian is trusted by global enterprises like Snowflake, T-Mobile, and Pure Storage. We protect more than 200 organizations across North America, Europe, the Middle East, Southeast Asia, Australia, and New Zealand—including many of the world's largest Fortune 1000 and Global 2000 companies.
With strong global momentum, a growing partner ecosystem including SentinelOne, Databricks, and Google Cloud, and a major fundraise on the horizon, we're scaling quickly toward long-term growth and IPO readiness. Join us as we define the future of SaaS security!
ROLE AND RESPONSIBILITIES
We are looking for a Technical Lead to drive the development of Obsidian's core ontology that powers our groundbreaking unified security config analysis, AI security, and threat detection product.
- Scale this ontology as part of a team of 3-6 software engineers and data scientists to cover hundreds or thousands more enterprise application platforms. Drive automation of repeatable R&D subtasks.
- Become an expert on foundational identity, authentication, authorization, network, and data security concepts. An unhealthy dose of curiosity about the design and administration — technology, people, and process — of complex application platforms such as GitHub, Salesforce, and Workday is a must. You will love exploring rabbit holes into esoteric domain knowledge related to these topics.
- Formulate security problems as data and ML problems, constantly addressing and refining the customer outcome in collaboration with top-flight security teams from Global 1000 companies.
BASIC QUALIFICATIONS
- 6+ years of experience in data science, machine learning, or applied research, preferably with 2+ years in a technical leadership role.
- A track record of shipping production ML or data systems at scale — ideally systems involving ontologies, knowledge graphs, entity resolution, or semantics over heterogeneous data sources.
- Expert-level proficiency in Python and modern ML/data tooling.
- Working knowledge of core security domains, or a strong ability to learn.
- Experience formulating fuzzy business or security problems as concrete ML/data problems:
- able to decompose ambiguous, ambitious problems into well-scoped subproblems and design experiments with statistical rigor.
- comfortable being scrappy and diving deep into vendor documentation, APIs, and audit logs to find the necessary data sources.
- Excellent written and verbal communication skills; ability to engage credibly with technical security practitioners at large enterprises.

Get Access To All JobsTips for Finding Tech Lead Jobs
Verify your specialty occupation documentation early
Tech Lead roles must meet the H-1B1 visa specialty occupation standard. Gather degree transcripts, a detailed job description naming your technical disciplines, and any organizational chart showing direct reports before you start outreach.
Target employers with active LCA filing history
Search employer Labor Condition Applications through the OFLC Wage Search to confirm a company has filed for software or engineering roles before. Employers experienced with LCA filings move faster once they extend an offer.
Use Migrate Mate to filter roles by H-1B1 sponsorship history
Search Tech Lead openings on Migrate Mate, which surfaces DOL Labor Condition Application data so you can identify employers who have sponsored Singaporean nationals and understand prevailing wage levels for your target location.
Confirm your employer enrolls in E-Verify before accepting an offer
H-1B1 employers must be enrolled in E-Verify to verify your work authorization. Ask your recruiter to confirm enrollment during the offer stage, since retrofitting this requirement delays your start date.
Map your compensation against DOL prevailing wage tiers
Use the OFLC Wage Search to look up the Level III or Level IV wage for your Standard Occupational Classification code in your target metro. Tech Lead roles typically fall at Level III or above, and your offer must meet or exceed that threshold.
Frequently Asked Questions
Does a Tech Lead role qualify as a specialty occupation under the H-1B1 Singapore visa?
Yes, provided the employer can document that the position requires a bachelor's degree or higher in a specific technical discipline such as computer science, software engineering, or a related field. A generalist management title alone may not satisfy the requirement, so your job description should name the technical domains you oversee and the degree field directly tied to that work.
How does the H-1B1 Singapore visa differ from the H-1B for Tech Lead applicants?
The H-1B1 Singapore visa skips the H-1B lottery entirely and is processed at the U.S. consulate in Singapore rather than through USCIS. The annual cap is 5,400 and has historically gone unfilled, so Singaporean Tech Lead candidates can apply year-round without waiting for a registration window or risking non-selection. The trade-off is that H-1B1 does not carry dual intent, so immigrant visa planning requires separate consideration.
How do I find Tech Lead employers who already sponsor the H-1B1 Singapore visa?
Migrate Mate filters Tech Lead roles by DOL Labor Condition Application filing data, letting you identify which employers have active sponsorship history for Singaporean applicants. Targeting companies with prior LCA filings for engineering roles shortens the time between offer and consulate appointment because their legal teams already know the H-1B1 process.
How long does the H-1B1 Singapore visa process typically take once I have a job offer?
Once your employer files and receives a certified LCA from DOL, which typically takes seven business days, you can schedule your consulate interview in Singapore. Appointment availability varies by season, but the overall timeline from offer acceptance to visa stamp is generally four to eight weeks for straightforward Tech Lead cases without additional administrative processing.
Can I change employers if I'm already in the U.S. on an H-1B1 Singapore visa?
You can change employers, but the H-1B1 does not carry the USCIS portability protections that H-1B holders use under AC21. Your new employer must file a fresh LCA and you must obtain a new H-1B1 visa stamp at the consulate before beginning work. Planning the transition carefully with your new employer's legal team prevents gaps in work authorization.
