About the Job

We are seeking a Senior Engineer to join our fully remote team and contribute to the growth and success of OpenSesame’s eLearning platform. As a Senior Engineer, you’ll work across the stack to develop new features, improve existing systems, and ensure high standards of performance and scalability. At OpenSesame, we are evolving toward Extreme Programming (XP) practices, and you’ll spend much of your time pairing or mobbing with other engineers to develop solutions collaboratively as we modernize and improve our systems.

This role requires a well-rounded engineer who can move seamlessly between front-end and back-end tasks, understands cloud infrastructure, and has experience with automated deployments. You’ll mentor and support other engineers, provide technical guidance, improve team processes, and help others level up their skills through XP practices such as test-driven development (TDD), continuous deployment, and evolutionary design.

“Help your team deliver valuable work with high quality and reliability.”

Performance Objectives:

In your first 90 days: Get fully integrated into the team’s workflow, develop a deep understanding of the product and architecture, and start contributing to collaborative development processes.

• Team Integration & Shared Ownership: Collaborate with the team to understand ongoing projects, key systems, and the current state of the product, with a specific focus on learning the legacy systems and their role in the platform.
• Contribute to Team Success: Actively participate in pair programming and mob programming to develop new features and resolve issues. Ensure the code the team produces is well-tested, scalable, and maintainable.
• Mentorship & Peer Support: Start mentoring team members by sharing insights, providing technical guidance, and supporting collaborative problem-solving. Help peers grow by offering constructive feedback and learning together through daily pairing and mobbing.
• Improve Team Processes: Engage fully in the team’s agile ceremonies, retrospectives, and discussions. Contribute to refining XP-based processes, such as test-driven development (TDD), to enhance team productivity and satisfaction.

Within 6 months: Take on more leadership in technical decision-making, guide the team’s development practices, and ensure quality in both code and process, while deepening your understanding of legacy systems and their modernization.

• Drive Team Decisions and XP Practices: Play a larger role in shaping the technical direction of the team, ensuring architectural decisions reflect the collective needs of the product. Act as a peer leader in XP practices, mentoring engineers in TDD, pairing, mobbing while embracing principles like “YAGNI” (“You aren’t gonna need it”) and “Do the simplest thing that could possibly work.”
• Lead by Example: Continue to engage in pairing and mobbing to lead important tasks within the context of team goals. Lead initiatives to improve systems, performance, and workflows in a way that benefits the whole team.
• Collaborative Development: Work closely with Product and Design to ensure features meet business goals and deliver value. Facilitate collaboration within the team to break down silos and encourage collective ownership. Ensure that everyone’s voice is heard in pairing and mobbing sessions.
• Incremental Delivery & Vertical Slicing: Help the team break down complex features into vertical slices that deliver incremental value. Encourage the team to focus on releasing small, functional increments to ensure fast feedback and continuous improvement, particularly in legacy areas where change may be more challenging.

By the end of your first year: Establish yourself as a technical leader within th
