Job description
Senior Full-Stack Software Engineer San Francisco, CA · On-site · Full-time
Compensation: $180K–$280K + equity
About the company
Our client is a seed-stage enterprise-AI company building a platform that captures the operational knowledge generated inside the world’s largest organizations and turns it into a living specification that agentic systems can operate from — working at the intersection of process intelligence and agentic AI. Just months in, they’re already transforming operations for large enterprises, and they’re backed by a top-tier venture firm. This is a chance to be one of the first engineers on a young, clean codebase with real technical ownership.
Founded 2024 · ~10 people · Industry: AI, Enterprise, B2B
The role
You’ll be a core early engineering hire building a production platform end-to-end. You’ll write idiomatic Go, ship a modern React frontend, and design systems that put LLMs to work in production — making architectural calls, living with the results, and iterating based on how things perform in the real world and what customers tell you.
What you’ll be doing
- Own features end-to-end, from design through deployment and monitoring
- Build and operate reliable backend systems in Go and Python
- Build and maintain a modern React/TypeScript frontend
- Design and ship production systems that integrate LLMs (orchestration, tool calling, context management, evals)
- Work directly with the founding team and iterate on features from direct customer feedback
Tech stack: Go, Python, PostgreSQL, Redis, React 19 + TypeScript, GCP, Terraform, Docker, Datadog, GitHub
Requirements
- 5–10 years of full-stack software engineering experience, with real strength in a typed language (Go preferred), Python, and React/TypeScript
- A track record of shipping production services with concrete, verifiable contributions across the stack and sustained ownership of meaningful systems
- Hands-on experience building production systems that integrate with LLMs (real systems, not just prototypes), with a working grasp of patterns like orchestration, tool calling, context management, and evals
- Solid PostgreSQL depth — schema design, migrations, and production operations
- Proven experience iterating on features from direct customer feedback, with strong written and verbal communication
- A pragmatic engineering mindset (knowing when to refactor vs. ship, build vs. buy) and a track record of leading larger, high-impact projects
- A genuine understanding of what it takes to be a founding engineer in an early-stage environment
- A BS or higher in Computer Science, Engineering, or a related technical field (a top-30 CS program is a plus, especially earlier in your career)
- Able to work on-site 5 days a week in San Francisco
Nice to haves
- Early-stage startup experience, or a mix of big-tech and startup backgrounds
- Infrastructure-as-Code experience (Terraform, GCP, Docker)
Why join
- Get in early on a category-defining product at the intersection of process intelligence and agentic AI
- Real technical ownership across the full stack in a young, clean codebase
- Work directly with a founding team that’s already in market with large enterprises
- Senior compensation plus meaningful early-stage equity

Visa sponsorship record
No public sponsorship records foundWe didn't find H-1B, H-1B1, E-3 or green card (PERM) filings under the name See more jobs at David Joseph & Companyexternal in the Department of Labor and USCIS data. That doesn't mean the job can't be sponsored — the company may file under a different legal name, be new to sponsorship, or sponsor a visa that isn't in these datasets (for example H-2B or J-1).
Tip: ask the recruiter early, in writing, which visa they sponsor and whether they cover the legal and filing fees.
Which visas can work for this job
Occupation: Software Developers (SOC 15-1252).
- Mentioned in the listing
H-1B, OPT
- H-1B cap-exempt employer
Regular cap-subject employer — a new H-1B needs to win the lottery in March (unless you already hold cap-counted H-1B status).
- TN (citizens of Canada and Mexico)
This kind of role may fit the USMCA profession “Computer Systems Analyst (or Engineer, for engineering-degree holders)” — it depends on the actual duties. No lottery, no cap; you need the matching degree or license.
- E-3 (Australia) and H-1B1 (Chile, Singapore)
Same degree requirement as H-1B, but no lottery and a separate quota that is rarely filled.
- O-1 (extraordinary ability)
For candidates with awards, publications, press, a high salary or critical roles at distinguished organizations. No cap, no lottery; the employer files a petition.
- STEM OPT extension (F-1 students)
Requires an E-Verify employer. We didn't find this company in the E-Verify list — ask HR.
Salary vs prevailing wage
Level II (qualified)Software Developers · San Francisco-Oakland-Fremont, CA. Annual prevailing wages set by the Department of Labor (OFLC).
| Level | Prevailing wage | H-1B lottery odds* |
|---|---|---|
| Level I | $137,093 | ~15% |
| Level II | $165,131 | ~31% |
| Level III | $193,149 | ~46% |
| Level IV | $221,187 | ~61% |
This job pays $180,000–$280,000 a year — that's Level II (qualified). In the wage-weighted H-1B lottery a Level II registration gets 2 entries; estimated selection chance about 31%.
* Odds are DHS projections for the FY2027 wage-weighted lottery (actual results vary by year and employer). Since the FY2027 cap season the H-1B lottery is weighted by wage level: Level I = 1 entry, II = 2, III = 3, IV = 4. The level is set by the offered wage against the prevailing wage for the occupation and worksite. Separately, a $100,000 fee for new H-1B petitions for workers outside the US was announced in 2025; as of September 2026 a federal court ruling keeps it unenforceable while appeals continue — check the current status.
