Senior Software Engineer (Multiple Teams)

Join Relay, a fast-growing fintech company on a mission to help small businesses succeed. As a Senior Software Engineer II, you'll lead architecture and high-risk work across interconnected systems, drive cross-team initiatives, and influence teams with different priorities. You'll have the opportunity to shape the technical direction of the company, improve delivery and operational effectiveness, and develop the next generation of technical leaders. Enjoy a competitive salary, equity, comprehensive health benefits, a hybrid work environment, and more.

• Lead architecture and the highest-risk work across interconnected systems, and set practical standards for quality, reliability, security, and maintainability.
• Own ambiguous, cross-team initiatives from problem definition through measurable outcomes by setting priorities, resolving dependencies, and keeping execution moving.
• Coach engineers and delegate meaningful ownership so you create more technical leaders instead of becoming a bottleneck.

• You thrive in fast-paced, dynamic environments and are comfortable navigating ambiguity and change
• You have driven cross-team initiatives from an ambiguous problem to measurable results
• You have led architecture for complex, interconnected systems and owned the highest-risk technical decisions
• You grow engineers by coaching and delegating real ownership, and you measure your success by the leaders you develop
• You connect technical trade-offs to customer impact, business priorities, cost, and risk
• You have created standards, tooling, or processes that improved how teams beyond your own deliver and operate
• You influence without authority, aligning teams and stakeholders through context and evidence
• Have worked in startups or high-growth tech companies
• Have experience with JavaScript (we primarily use TypeScript, React, and Node.js)
• Have working knowledge of AWS services (ECS, S3, RDS, Dynamo, Lambda) and continuous deployment pipelines
• Have experience in fintech, banking, or other regulated environments
• You own your work: You take pride in your work, follow through on commitments, and feel a deep sense of responsibility for outcomes, not just tasks
• You build with AI, not just use it: You're actively embedding AI into how you work, pushing what's possible, and bringing your team along with you
• You push relentlessly for reinvention: You're always asking "how can this be better?" -- in your work, in your craft, in yourself. Comfort is a signal to push harder, not coast. You'd rather build something better than defend something familiar
• You crave autonomy: We trust our team with big challenges and the freedom to solve them. If you’re someone who takes initiative, is comfortable taking risks, and seeks input when needed, you’ll find the freedom here empowering
• You care about impact, not noise: You care deeply about the substance of your work. You measure success by results, not recognition, and you let your work speak for itself
• Small businesses are why we're here: Relay exists to help them thrive -- and that mission has to resonate with you
• You seek out feedback: You see directness as respect, not criticism. You actively seek input, sit with hard truths, and use feedback as fuel for improvement
• You’re energized by complexity and ambiguity: You enjoy tackling problems that don’t come with a playbook. You’re comfortable building from scratch, iterating as you go, and collaborating to shape the best path forward
• You're encouraged to apply even if your experience doesn't perfectly match the job description -- your perspective and drive matter more. We welcome diverse backgrounds and people who think critically, challenge the status quo, and want to help small businesses thrive
