You will lead backend engineering initiatives focused on high-performance, scalable, and reliable systems, while continuing to contribute actively to architecture, coding, code reviews, and technical decision-making. The ideal candidate has previously worked as a backend lead, tech lead, lead engineer, or equivalent, has led backend engineers, and has personally owned production systems operating at a meaningful scale.\nResponsibilities:\nLead backend engineers in designing, developing, and scaling high-performance production systems.\nDrive architecture and technical decisions for APIs, distributed services, asynchronous workflows, and data-intensive applications.\nRemain hands-on with coding and production engineering, rather than operating purely in a managerial capacity.\nConduct design reviews and code reviews, establish engineering best practices, and improve code quality.\nMentor and coach backend engineers and help the team improve engineering depth.\nDelegate effectively while maintaining ownership of technical quality and delivery.\nIdentify and resolve latency, reliability, scalability, and performance bottlenecks.\nDesign systems capable of handling high traffic, concurrency, and complex database workloads.\nOwn production incidents, root-cause analysis, and reliability improvements.\nDrive safe migrations, architectural evolution, and performance/cost optimization.\nWork closely with product and engineering stakeholders to translate requirements into robust technical solutions.\nRequirements:\n4-7 years of professional software engineering experience.\nStrong production experience in at least one of Python, Go, or Rust.\nStrong understanding of backend architecture, distributed systems, and scalable service design.\nExperience building and operating production APIs/services at scale.\nStrong understanding of databases, caching, asynchronous processing, and failure handling.\nExperience troubleshooting and improving system latency, throughput, reliability, and scalability.\nTechnical Leadership:\nPrior experience as a backend lead, tech lead, or lead engineer.\nSenior engineer with significant technical leadership responsibility.\nYou should have demonstrated experience with: Technical/design ownership, code reviews, architecture decisions, delegation, mentoring and coaching engineers, Delivery accountability, leading backend engineering initiatives.\nFormal people management is not mandatory, but genuine technical leadership of backend engineers is required.\nCloud and Production:\nHands-on experience deploying and operating backend systems in the cloud.\nGCP experience is preferred.\nAWS experience is also relevant.\nStrong understanding of production environments, observability, reliability, and incident management.\nHigh-Performance Systems Experience:\nWe are particularly interested in engineers who have personally worked on systems involving: High-throughput APIs, high concurrency, transaction processing, distributed systems, asynchronous/event-driven architectures, complex database workloads, performance and latency optimization, reliability and failure recovery, Large-scale data processing, cost optimization, production
