With our growing customer base and our expansion into new markets and use cases, we have more to build than ever at Affinity as we execute on our vision to put relationship intelligence at every professional's fingertips.

As a Senior Software Engineer II, you’ll have the opportunity to drive our product forward, refining and evolving the features our customers love while pushing new directions. You’ll shape key frontend components, including design systems, state management patterns, and overall architecture. Affinity’s user experiences are data-dense and highly interactive, offering a challenging and rewarding role with significant impact.

In this role, you will:

• Work with a cross-functional group leading the frontend engineering projects from design to delivery, ensuring successful execution and outcomes.
• Scope and stage work into well-defined milestones, avoiding monolithic deliverables and ensuring timely progress.
• Identify and proactively address technical debt, maintaining the long-term health and performance of systems.
• Mentor other engineers, providing technical guidance, conducting code reviews, and improving team practices.
• Drive operational excellence, influencing decisions that enhance the scalability and maintainability of our frontend systems.

At Affinity, we are dedicated to building a diverse, inclusive, and authentic workplace, so if you’re excited about this role, but your past experience doesn’t perfectly align with the qualifications above, we encourage you to apply anyways. You may be just the right candidate for this or other roles.
