Technical Partnerships Engineer

Washington, DC (5 Days Onsite) $160,000 - $200,000 Base Salary + Equity

A high-growth fintech infrastructure company is hiring a Technical Partnerships Engineer to join its engineering team in Washington, DC. This is a unique opportunity for a software engineer who enjoys both building products and partnering directly with technical customers.

Unlike a traditional Solutions Engineer role, you'll remain deeply hands-on with code while working closely with product and engineering teams at enterprise customers. You'll help customers integrate APIs, SDKs, and developer tools, troubleshoot complex technical issues, and build internal products that improve the overall customer experience.

The company powers critical financial infrastructure used by more than one million end users through its customers' platforms and is investing heavily in AI-native products, LLM applications, and agentic workflows.

• Serve as a technical partner to customer product and engineering teams
• Help customers integrate and leverage APIs, SDKs, developer tools, and embedded products
• Investigate and resolve complex technical issues across multiple customer accounts
• Write production-quality code to improve both customer-facing and internal systems
• Design technical solutions rather than simply configuring existing tools
• Communicate technical concepts clearly through Slack, tickets, documentation, and customer calls
• Identify recurring challenges and build scalable engineering solutions
• Partner closely with Product, Engineering, and Customer teams to influence roadmap decisions

Deeply Technical, Client-Facing Role - Work directly with engineering and product teams to solve complex API and integration challenges

Build Internal Products & Systems - Own engineering projects that improve scalability, tooling, and the customer experience

Blend Engineering + Customer Partnership - Stay hands‑on with software development while serving as a trusted technical advisor

High Ownership & Impact - Influence product direction through direct customer feedback and technical problem solving

AI-Native Environment - Work closely with emerging AI, LLM, and agentic software applications

Strong Growth Opportunity - Join during a period of rapid product expansion with significant career mobility

• 3-10 years of software engineering experience
• Strong computer science fundamentals and engineering background
• Experience with APIs, SDKs, integrations, or developer platforms
• Ability to investigate, diagnose, and solve complex technical issues independently
• Excellent written and verbal communication skills
• Comfortable working directly with external engineering and product teams
• Interest in combining software engineering with technical customer engagement
• Curiosity around AI, LLMs, and emerging developer technologies
• Meaningful equity package
• High-impact role with significant ownership
• Opportunity to work alongside highly technical startup operators and engineers

This role is ideal for engineers who enjoy solving difficult technical problems, building customer-facing solutions, and working at the intersection of software engineering, product, and customer success without giving up hands-on coding.
