• Drive cross-team or cross-discipline initiatives, optimizing beyond your immediate team for broader organizational impact

𝙏𝙚𝙘𝙝𝙣𝙞𝙘𝙖𝙡 𝘾𝙧𝙖𝙛𝙩

• Design the software and systems in your area of ownership, ensuring they meet their design objectives and align with longer-term business needs

• Handle complex software modules that are logically dense — whether from business, idempotence, robustness, or scalability requirements

• Simplify code and infrastructure, prioritizing tasks that measurably reduce maintenance and migration costs

• Preemptively identify and resolve technical risks before they jeopardize projects; resolve cross-team dependencies early

• Debug and reproduce non-deterministic bugs and system issues that would normally escape less experienced engineers

• Champion an AI-first engineering culture — actively adopt and advocate for AI tools and assistants to maximize productivity, accelerate delivery, and multiply your team's impact

𝗟𝗲𝗮𝗱𝗲𝗿𝘀𝗵𝗶𝗽 & 𝗦𝘁𝗿𝗮𝘁𝗲𝗴𝘆

• Define the technical roadmap for complex projects, provide leadership for those executing on it, and generate excitement for the team's strategy

These are non-negotiable. We need engineers who can hit the ground running with our stack and ways of working.

• Strong proficiency in at least one backend language: Python, Java, or Node.js, with deep understanding of language internals and performance characteristics

• Proven track record of designing, building, and operating microservices architectures at scale in production

• Deep experience with cloud platforms (GCP, AWS, or Azure) including architecture decisions, cost optimization, and multi-region deployments

• Expert-level knowledge of containerization (Docker) and orchestration (Kubernetes) in production environments

• Strong experience with CI/CD pipelines, deployment strategies (blue-green, canary), and automated quality gates

• Advanced database skills: query optimization, sharding strategies, replication, and data modeling for high-throughput systems

• Extensive experience with event-driven architectures and message brokers (Kafka, SQS/SNS, Pub/Sub) at scale

• Deep understanding of caching layers (Redis, Memcached, CDN) and their role in system performance and reliability

• Strong grasp of API security, OAuth 2.0, JWT, API gateway patterns, and WAF configurations

• Domain experience in e-commerce, retail, logistics, supply chain, or similar high-traffic consumer platforms — you understand the business domain, not just the technology

𝗡𝗜𝗖𝗘-𝗧𝗢-𝗛𝗔𝗩𝗘 𝗤𝗨𝗔𝗟𝗜𝗙𝗜𝗖𝗔𝗧𝗜𝗢𝗡𝗦

These will set you apart and accelerate your impact, but aren't required on day one.

• Experience leading technical design reviews and architectural decision records (ADRs) for cross-team systems

• Track record of driving large-scale migrations, platform re-architecture, or system decomposition projects

• Hands-on experience with observability at scale: custom metrics, distributed tracing, SLO/SLI frameworks, and incident management

• Experience with infrastructure-as-code (Terraform, Pulumi) and platform engineering practices

• Background in high-stakes transactional systems: payment processing, order management, or warehouse/logistics platforms

• Public contributions: conference talks, technical blog posts, open-source maintainership
