As a Senior Fullstack Engineer for the MT Inbox crew, your mission is to be an engineering leader, driving high-impact initiatives to provide reliable and scalable email client solutions to our customers. This role requires independent handling of complex technical communication with stakeholders and clients, ensuring the system's performance and reliability. You will also be responsible for mentoring and coaching junior and mid-level engineers to foster engineering excellence within the team.

Key Responsibilities

  • Design and Build End-to-End Features: Develop scalable and high-performance frontend and backend systems, working across the stack with technologies like AWS, K8S, Ruby on Rails(including Sidekiq), Python and Vue.js.

  • Lead Strategic Alignment and Initiatives: Drive high-impact engineering initiatives and manage technical communication with engineering managers, product managers, designers, and customers independently to ensure solutions align with critical business and reliability requirements.

  • Champion Engineering Excellence: Write robust, maintainable code and implement best practices around testing, CI/CD, performance, observability and reliability.

  • Architect Scalable Systems: Design and implement distributed systems and microservices with event-driven architecture using Kafka.

  • Maintain and Scale Tech Stack: This role offers a unique balance - you'll lead the scaling efforts of our production Rails environment to keep pace with our growth, while simultaneously architecting 'greenfield' components as we refactor toward our future-state tech stack.

  • Mentor and Coach: Serve as an engineering leader by mentoring junior and mid-level engineers on development best practices, engineering operational excellence, and complex system design.

  • Own Operations and Reliability: Take part in monitoring, incident response, production support and performance tuning across the stack.

  • Strong expertise in designing, implementing, and maintaining microservices architectures.

  • Solid hands-on experience with Kafka and event-driven systems.

  • Proficiency in MySQL, Elasticsearch, and Redis.
