Built for Fast-Moving Bay Area Tech Ventures

San Francisco founders and CTOs cannot afford slow turnarounds or junior code that accumulates tech debt. We deliver senior-level engineering designed to integrate with your existing codebase.

B2B SaaS Scale-Ups

High-converting marketing sites, interactive pricing calculators, product tour architectures, and authentication onboarding funnels that turn visitors into product-qualified leads.

AI & Machine Learning Startups

API-driven dashboard interfaces, interactive model playgrounds, documentation hubs, and technical entity graph SEO that positions your AI tool for Perplexity citations.

Seed-to-Series-B Teams

Flexible sprint-based engineering augmentation to help in-house engineering leads meet urgent product release dates without the months-long local hiring drag.

Developer Tools & APIs

Developer-focused landing pages, interactive code snippet switchers, fast CLI documentation portals, and GitHub integrated workflows.

The Startup Advantage

Maximum Engineering Output. Minimum Runway Burn.

Hiring full-time senior developers in San Francisco requires $220k+ base salaries plus benefits and equity. Local SF agencies bill upwards of $250/hr. ONS Tech provides direct access to battle-tested senior engineers on a transparent fixed-price or sprint model.

Modern Production Stack

We write clean TypeScript, React, Next.js App Router, Tailwind CSS, Node.js, and Python. We maintain high test coverage, strict linting, and spotless documentation.

Guaranteed Pacific Time Overlap

Daily working overlap (9:00 AM – 1:00 PM PT) for real-time Slack discussions, sprint standups, and PR reviews during your core office hours.

Zero Middlemen Or Bureaucracy

You speak directly to the engineers building your software. Rapid PR merges, immediate bug fixes, and transparent Git commit logs.

Bay Area Engineering Model Comparison

Local SF Agency / Contractor $200 – $300/hr

High billing rates to support SF commercial rents and account management tiers. Slower sprint velocity and rigid change-order fees.

ONS Tech Senior Remote Team Senior Output • 65% Capital Savings
