Api Technical Writer Remote Jobs in California (NOW HIRING)

Founded in 2020 by a team of leaders from Braintree, PayPal, and Lending Club, Highnote is an embedded finance company that sets the standard in modern card platform management. As an all-in-one card issuer processor and program management platform, we provide digital-first organizations with the flexibility to seamlessly issue and process payment cards, embed virtual and physical card payments, and integrate ledger and wallet functionalities—empowering businesses to drive growth and profitability.

We've raised $145M+ and have grown our team to 140+ employees. Headquartered in San Francisco, we've managed to build one of the most advanced payments teams in the industry, with team members in 25+ US states.

Operating through our core values of customer obsession, executional excellence, intentional inclusion, we're helping businesses grow for the future by creating the payment products demanded by tomorrow, with the ability to solve for use cases that don't exist yet.

We are fast-moving, hands-on, and strongly believe everyone deserves a seat at the table. We believe we're unlocking incredible opportunities that can change the future of payments, as long as we have the right people to make it happen.

Highnote is looking for a Senior Technical Writer to own our developer documentation. You'll set the voice and standards for how we explain card issuing, acquiring, and money movement to developers — and build the tooling that holds that standard as the platform grows. You'll join Developer Experience, the team that owns our API, our SDKs, our docs, and our design.

• Own our API documentation: reference, developer guides, and tutorials
• Collaborate with the engineers who build the API you're documenting, and support the PMs shipping it
• Set the voice, tone, and style of our docs, and encode that standard into our tooling so it holds across content you didn't write yourself
• Build and refine AI workflows that draft, review, and keep documentation in step with the API
• Treat AI agents as a first-class audience alongside human developers
• Structure the documentation so it scales as the product grows
• Build a strong working grasp of card issuing, acquiring, and money movement. Enough to write about them accurately, and to know when to go ask
• Define how we measure documentation quality, and use it to decide what comes next

• 5+ years across technical documentation and software: as a writer, a docs engineer, or an engineer who owned a documentation system
• Docs-as-code: Markdown or MDX in a static site generator, versioned in git
• Comfortable working like an engineer: branches, pull requests, and CI
• Hands-on experience building AI-backed documentation tooling: generation, review, or drift checks you've shipped and kept running
• Editorial instinct sharp enough to state as a rule a machine can follow
• Able to read an API schema and write valid requests against it: we're GraphQL, and strong REST/OpenAPI experience is a good foundation; you'll be working in GraphQL from week one
• Strong writing for a developer audience

• Scripting in TypeScript, JavaScript, or Python
• Fintech, payments, or card-issuing experience

• We're a startup that allows for our employees to truly build from the ground up and impact every layer of our organization.
• We're a team of payments obsessed individuals. While some of us come from the fintech world, some of us don't. We value the varied backgrounds and the diverse perspectives of our employees.
• We're small on hierarchy and big on growth. We're a flat organization that allows everyone to have direct exposure to our leadership team. We are looking for builders who thrive in ambiguity.
• We're backed by Oak HC/FT, Costanoa Ventures, Adams Street Partners, Westcap, and Pinegrove Venture Partners. Angel Investors include Bill Ready (CEO at Pinterest) and Renaud Laplanche (Co-Founder & CEO of Upgrade).

• Flexible Paid Time Off
• 100% healthcare coverage + 75% coverage for dependents
• 401k program
• Paid Parental Leave: Up to 16 weeks paid leave for the birth parent, and up to 6 weeks paid leave for the non-birth parent
• Equity in Highnote
• Stipend to build out your home office; internet and phone reimbursement
• At Highnote we have built a total rewards philosophy that includes fair, equitable, geo-based compensation that is performance and potential based. Our compensation packages are competitive based on robust market research and are a combination of a cash salary, equity, and benefits. In compliance with the Equal Pay for Equal Work Act, the annual salary range for applicants is $150,000-$200,000.

We provide flexible work options based on distance from our downtown SF office. Highnote believes in the power of face-to-face, personal connection. As a result, we prioritize in-person candidates.
