Lead Software Engineer - Systems

Impact you can create Architect From Scratch: Take complete ownership of building multi-tenant, cloud-native applications from scratch and guiding them through multiple production iterations. Guarantee Production Excellence: Ensure mission-critical systems achieve high availability (99.99%+), robust security, and deep observability. Act as a Force Multiplier: Mentor 2–4 systems engineers, raise the bar for code quality through reviews, and lead technical conversations across multiple engineering teams. Drive Efficiency Through Innovation: Harness and apply cutting-edge AI tools and technologies to optimize internal development workflows and platform capabilities. Roles & Responsibilities End-to-End Lifecycle Ownership: Own the entire lifecycle of feature and infrastructure delivery, from gathering functional and non-functional requirements to design, implementation, and production support. System & Service Architecture: Design, develop, and architect reliable, modular APIs and distributed services to support highly scalable, multi-tenant cloud applications. Code Optimization & Scaling: Lead major engineering initiatives focused on code optimization, refactoring, performance tuning, and scaling existing backend systems. Production Governance: Ensure maximum system resilience, establishing robust monitoring, telemetry, rate-limiting, and multi-region deployment configurations. Cross-Functional Partnership: Collaborate with Site Reliability Engineers (SREs), Product Managers (PMs), and fellow Tech Leads to deliver cohesive, platform-wide capabilities. Engineering Standards Advocacy: Drive organization-wide adoption of best practices for Object-Oriented Programming (OOP), design patterns, and SOLID principles. Skills Core Computer Science Foundations: Expert-level knowledge of Data Structures & Algorithms (DSA), with a strong command of time/space complexity trade-offs. High & Low-Level Design (HLD/LLD): Proven capability to design scalable, fault-tolerant end-to-end sy
