Role Responsibilities: What You'll Do

• Conceptualize and own technical solutions end-to-end, organizing effective groups of engineers to brainstorm, design, and deliver impactful work.
• Invest in experimenting and building platform solutions that improve the developer experience for all product teams.
• Oversee the entire process from the development of software components to testing, deployment, release, and monitoring across all environments.
• Collaborate closely with product teams to support platform-specific migrations and translate their challenges into effective solutions to improve platform reliability.
• Teach engineers (especially new joiners) how to use our tools by giving internal talks, organizing onboarding workshops, or writing documentation and tutorials.
• Manage technical debt, refactor existing solutions, and improve the team’s approach to system architecture, design patterns, coding principles, and code review.
• Leverage your experience to drive platform advancements, ensuring high-quality, reliable, secure, and cost-effective product and platform solutions.

How You’ll Go About It

• Influence and strengthen team culture while identifying areas for improvement.
• Show technical excellence through hands-on involvement in projects and continuous learning.
• Maintain open and clear communication and foster a collaborative work environment with team members, stakeholders, and management.
• Ensure comprehensive and up-to-date technical documentation.

• 5+ years of software engineering experience.
• Proven experience designing, building, documenting, and distributing robust and delightful platform solutions end-to-end with a focus on high-quality, reliable, and operational excellence.
• Deep understanding and interest in DevOps tools and technologies such as Kubernetes, AWS (CDK, ECS, Fargate, etc.), Gitlab, DataDog, Sentry, Projen, Backstage, Docker, and progressive delivery automation (CI/CD pipelines, feature flags, canary deployments, service mesh).
• Proficiency in Kafka operations and building platform tools that utilize Kafka. Hands-on experience with database technologies (Debezium, data capture, etc.) is a plus.
• Interest in development processes and practices (merge requests, approvals, trunk-based vs branch-based development) and an eagerness to optimize and automate them.
• Experience in creating, deploying, and operating data streaming applications with technology like Kafka Streams.
• Experience acting as a mentor or role model to other engineers is a plus, ideally leading pair programming sessions and technical brainstorming and solution design sessions.
