Sales Engineer

About Us:

At Parafin, we’re on a mission to grow small businesses.
Small businesses are the backbone of our economy, but traditional banks often don’t have their backs. We build tech that makes it simple for small businesses to access the financial tools they need through the platforms they already sell on.
We partner with companies like DoorDash, Amazon, Worldpay, and Mindbody to offer fast and flexible funding, spend management, and savings tools to their small business users via a simple integration. Parafin takes on all the complexity of capital markets, underwriting, servicing, compliance, and customer service for our partners.
We’re a tight-knit team of innovators hailing from Stripe, Square, Plaid, Coinbase, Robinhood, CERN, and more — all united by a passion for building tools that help small businesses succeed. Parafin is backed by prominent venture capitalists including GIC, Notable Capital, Redpoint Ventures, Ribbit Capital, and Thrive Capital. Parafin is a Series C company, and we have raised more than $194M in equity and $340M in debt facilities.
Join us in creating a future where every small business has the financial tools they need.

About the Position

We are expanding our GTM technical team and seeking a Sales Engineer to act as the technical lead for our prospective platform partners. In this role, you will guide partners through technical discovery, integration scoping, and solution design during the pre-sales process, ensuring a smooth handoff to post-sales implementation.

You will work at the intersection of sales, partner engineering, product, and engineering, helping partners understand how Parafin’s embedded financial products fit into their platform architecture and business goals. You’ll also play a key role in shaping Parafin’s technical pre-sales motion as we scale.

You will report to the Partner Engineering Manager and be a part of Parafin’s Revenue function, collaborating closely with Sales, Platform Growth, Product, and Engineering.

What You’ll Do:

• Lead technical discovery and pre-sales scoping with prospective partners and their engineering teams, serving as the primary technical point of contact through the sales cycle

• Design and communicate integration approaches for Parafin’s financial products, balancing partner constraints, scalability, and time to launch

• Present technical solutions to a range of audiences, from engineering to C-suite stakeholders, clearly articulating tradeoffs, ROI, and implementation considerations

• Build product-quality demos, reference implementations, and proofs of concept to demonstrate feasibility and partner fit

• Develop integration architectures, diagrams, and technical documentation to support smooth transitions to post-sales implementation teams

• Create sales enablement materials and demo tooling that help the broader GTM team sell more effectively

• Identify product gaps, edge cases, and recurring partner needs, and collaborate with Product and Engineering to influence product roadmap, improve platform capabilities, and optimize the sales cycle.

• Help define and refine technical pre-sales processes, tooling, and best practices as Parafin’s Sales Engineering function grows

• Act as a trusted technical advisor to prospective partners, helping them understand how embedded finance can unlock value for them, and their small business customers

• Contribute to building a scalable, repeatable technical sales motion that supports Parafin’s growth trajectory

What We’re Looking For:

• 3+ years of client-facing technical role such as Sales Engineer, Solutions Engineer, Solutions Architect, or Technical Account Manager

• Strong understanding of software systems and integration patterns, including: RESTful APIs and authentication (OAuth, API keys), webhook event handling and retry logic, Embedded UI components (iframes, web components, SDKs), async data flows and reconciliation patterns, common partner platform architectures (marketplace, SaaS, fintech)

• Ability to reason about and explain system architecture, data flows, and edge cases without needing to own core production engineering

• Comfortable reading and navigating a modern codebase to:

  • Debug integration issues during pre-sales POCs

  • Understand API behavior and error handling

  • Collaborate with Engineering on feasibility questions

  • Review partner code samples and provide feedback

  • Note: You won't own production code, but should be comfortable in GitHub/IDEs

• Experience creating realistic demos, POCs, or reference applications that support customer understanding and decision-making

• Excellent communication skills, with the ability to translate complex technical concepts for both technical and non-technical audiences

• Strong judgment around when to go deep technically and when to keep things high-level, depending on the partner and stage of the deal

• Ability to thrive in a fast-paced, ambiguous environment and contribute to building scalable GTM processes

• Passion for helping small businesses succeed and interest in embedded financial products

Nice to have

• Experience with React and/or Scala

• Background in fintech, payments, or embedded finance

• Prior experience at a high-growth B2B SaaS or API-first company

• Familiarity with underwriting, capital products, or lending operations
