Overview

Senior AI engineering for San Francisco SaaS, AI startups, fintech, and healthtech.

San Francisco is where AI hiring goes to die — base comp for a senior AI engineer in SF Mission Bay or SoMa now clears total packages that few non-FAANG operators can absorb without distorting their burn, and the buyers we work with here typically arrive after the same conversation. They have tried to hire a senior AI engineer out of the open market and lost the offer to Anthropic, OpenAI, Anysphere, or a stealth foundation-model lab. They have priced a Bay Area AI consultancy at $400-to-$700-per-hour senior rates and watched a six-month discovery phase end in a deck rather than a system. They have a board deadline for an AI feature and an in-house team already at capacity. We exist for what comes after that. Fifty-plus production AI systems shipped across 12 industries tell the same story: RAG pipelines that hold up in front of your own customers, voice agents clearing sub-second p95 latency, and agentic features threaded into live SaaS products with the host architecture left untouched.

What separates Aiinfox from a typical Bay Area AI consultancy for SF buyers in 2026 is the engineering discipline around the model, not the model itself. We write the eval harness before the prompt. We pin LLM inference to AWS US-West-2 (Oregon) or US-West-1 (N. California) when CCPA, CPRA, your customer's security review, or a multi-state-SaaS DPA requires it, and we will run the entire build inside your AWS, Azure, or GCP account when your team prefers to own the runtime. For SF healthtech, HIPAA BAAs are signed before any PHI is shared and US-West VPC deployment is the default. For SF fintech serving New York counterparties, we map controls to NY DFS Part 500 in parallel with CCPA + CPRA, so a single audit-log schema satisfies both California and New York obligations. SOC 2-aligned controls are standard. Self-hosted Llama 3 on vLLM is supported for AI-startup clients with strict no-third-party-API positioning or for SF healthtech operators whose customers will not permit egress to a managed inference API. Senior engineers only — eight years average experience per engineer, no junior pool hidden behind a senior nameplate.

Every SF call eventually gets to the same question — can a Texas-and-India team actually be present for Pacific Time — so here is the straight version. Central Time runs two hours ahead of Pacific, and our Frisco, TX pod absorbs that gap with a late-CT shift (roughly 11am-to-8pm CT) built specifically to keep engineers live on Zoom for your 9am-to-6pm PT day. Mohali's early-IST rotation then picks up SF afternoons in real time, so coverage does not thin out as your day goes on. What that buys you: twice-weekly demos inside SF business hours, async updates waiting before your standup starts, and the same senior engineer on the kickoff call writing your code through launch — nobody swaps to a junior pool once week three hits. The delivery clock runs six weeks from kickoff to a working v1, the scope is fixed-price and locked within 72 hours, and any overrun on our side is our cost, not yours. On rate, senior engineering here runs roughly 50 to 70 percent below a typical Bay Area AI consultancy — a real number, but the actual differentiator is a shipped system instead of a sold discovery phase.

FAQ

Questions teams actually ask.

Do you have a San Francisco or Bay Area office?

There is no Bay Area office to point to — Aiinfox runs out of Mohali, India and Frisco, Texas. Pacific business-hours coverage comes from Frisco's US-Hours rotation: a late-CT shift puts senior engineers on Zoom for your full 9am-to-6pm PT day, and Mohali's early-IST start takes over for SF afternoons. On-site work — kickoff days, milestone reviews, security walk-throughs — happens on a scheduled trip to SF rather than through a permanently staffed local office billed at Bay Area rates.

Can a Texas- and India-based AI team really cover Pacific Time business hours?

Yes, but only because we planned the shift deliberately rather than assuming it would just work out. Frisco, TX sits on Central Time, two hours ahead of Pacific, so our standard 9am-to-5pm CT day only overlaps your morning. SF engagements run on a separate US-Hours rotation instead — a late-CT shift, roughly 11am-to-8pm CT, that fully covers your 9am-to-6pm PT day on Zoom. That is what keeps twice-weekly demos inside PT business hours, async updates landing ahead of your SF standup, and the same senior engineer on the kickoff call through launch. The one honest exception: if your engagement truly needs boots on the ground in the Bay Area at all hours, we will say so on the first call and point you to a local consultancy instead.

Are you CCPA and CPRA aligned for California clients?

Yes. Our engagement defaults are aligned with the California Consumer Privacy Act and the California Privacy Rights Act amendments. DPAs are signed before any personal information is shared; data-subject rights workflows (access, deletion, correction, opt-out of sale or sharing) are mapped at scope; audit logs on every model and tool call are exportable for a California Privacy Protection Agency inquiry. For SF clients with operations in multi-state SaaS, we map the CCPA + CPRA controls in parallel with NY SHIELD, NY DFS Part 500 where financial services apply, and the Colorado / Virginia / Connecticut state privacy obligations — one audit-log schema, multiple regulator-facing exports.

Where will my data and AI workloads physically run?

You call the region. AWS US-West-2 (Oregon) is the SF default — lowest-latency west-coast region with full AWS service coverage — and US-West-1 (N. California) is the second option when a customer wants California-only residency. We will run inside your AWS, Azure, or GCP account in whichever US region you name. Claude (Anthropic) and GPT-4o (Azure OpenAI) route to US-West endpoints explicitly; AI-first startups with strict no-third-party-API positioning get Llama 3 self-hosted on vLLM inside their VPC instead, with zero data egress to non-customer endpoints. Your DPA spells out the exact data path.

Do you sign MSAs, NDAs, and BAAs on Bay Area-style commercial terms?

Yes. We work with MSA-plus-SOW structures for ongoing engagements and single-document fixed-price agreements for pilots. Standard terms cover IP assignment (your code, your IP), limitation of liability tuned to scope, indemnification, data handling, breach notification, and a 30-day production warranty. NDAs are mutual and signed before any technical detail is shared. BAAs are signed before any PHI is shared. We are a registered Indian entity (Aiinfox Pvt. Ltd.) invoicing US clients in USD via wire transfer as a foreign corporation — no W-9 or 1099 entanglement on your side.

Can you take over a stalled AI project from a Bay Area consultancy?

Yes — takeover audits happen often enough that we have a fixed process. First we read: the code, the data pipelines, any eval results that exist, the prompts, and the cost telemetry. Second we ship — the smallest valuable change that proves we actually understand the system, not a re-pitch of what is already broken. Third we recommend a direction, honestly, on the first call: incremental stabilization, a parallel rewrite, or shutting it down. Most Bay Area takeovers we have seen did not need the full-rewrite option — what they were missing was evals, guardrails, observability, and a senior engineer who stayed on past the discovery-phase pitch.

How does Aiinfox compare on cost to a Bay Area AI consultancy?

SoMa, Mission, Mid-Market, and Peninsula AI consultancies commonly bill $400 to $700 an hour, run discovery phases that stretch for months, and either stack junior hours behind a senior nameplate or lose their best engineers to a foundation-model lab partway through. Aiinfox's senior engineering rate sits roughly 50 to 70 percent below that range. Our commercial model is fixed-price and six weeks: the senior engineer on your kickoff call is still writing code at launch, and any overrun on our side is absorbed by us, not billed to you. Total cost for most SF engagements lands 60 to 75 percent below the Bay Area baseline, with the senior engineer in the room for every standup.

What does success look like on a typical SF engagement?

A working v1 in production six weeks after kickoff, with evals, guardrails, observability, and audit logs wired in from week one — not retrofitted after launch. For SF SaaS scale-ups, success is typically a shipped AI feature embedded in the product that moves a customer metric and survives security review at enterprise buyers. For AI-first startups, success is a fine-tuned model or RAG pipeline that clears a custom eval bar at production latency and cost. For SF healthtech, success is a BAA-covered RAG or ambient scribe with zero policy-violating answers in 90 days of production traffic. We measure against your acceptance criteria, written into scope before kickoff.
