What You'll Do

  • Collaboratively develop features and improvements. You ll build features and embed improvements to the OutThink platform in a secure, well-tested and performant way. You ll collaborate with the Product team and other stakeholders within Engineering (Frontend, UX, etc.) to maintain a high bar for quality in a fast-paced, iterative environment.

  • Build upon technical expertise within the engineering organization. You ll solve technical problems of medium scope and complexity. You ll have a demonstrated ability to both diagnose and prevent these problems.
  • Thought leadership and bias for action. You ll advocate for improvements to product quality, security, and performance that have impact across the team, in the process influencing the overall objectives and long-range goals of the team. You ll craft code that meets our internal standards for style, maintainability, and best practices for a high-scale SaaS environment.
