Expectations

We're building mission-critical software for some of the most demanding clients in finance. Here's what that means in practice:

• Ownership over tickets: You'll work within structured sprints, but we expect you to think critically, ask clarifying questions, and take ownership of outcomes — not just check off tasks.
• Delivery-focused culture: We measure success by shipped features and real product impact, not story points or hours logged.
• Full-time commitment: This is a dedicated role requiring 45–50 hours per week. We don't have rigid hours, but expect most work to wrap up by 7 PM your local time. We're looking for engineers who are fully invested in Pinnakl's success — this isn't compatible with side-freelancing.
