• Design and build the platform that Burq scales on for the next several years • Own and execute the AWS account split — separating production, staging, and development into clean isolated environments • Lead the Aurora DB production migration with support from our infrastructure advisor • Manage and evolve our ECS Fargate services, RDS clusters, ElastiCache, SQS queues, and ALB configuration • Own Terraform — infrastructure as code, not click-ops • Harden IAM — developer permission sets, production access controls, least-privilege enforcement • Audit and lock down public S3 buckets • Enable AWS Config and Security Hub across all accounts • Own SOC 2 Type 2 readiness maintenance in partnership with Sprinto • Coordinate external penetration test cadence • Own and improve our GitHub Actions CI/CD pipelines — build times, test reliability, deployment velocity • Build out PR stack environments so product teams can test independently • Drive the local development stack initiative — Docker Compose-based environments that replace shared preprod • Integrate AI-assisted testing into the CI pipeline • Own CloudWatch dashboards spanning ALB, ECS, RDS, ElastiCache, SQS, and target group health • Lead post-incident reviews and ensure every incident produces a runbook entry • Partner with product teams to distribute platform work as a standing sprint allocation — not a separate queue

• As an iOS Engineer on App Platform, you'll focus on the infrastructure and building blocks that feature teams rely on: architecting and maintaining core components and the design system, strengthening our networking and persistence layers, driving app stability and crash reduction, and partnering closely with product teams to make sure the "right way" to build is also the easiest way. • It's a high-leverage role for someone who wants their work to compound across the entire app rather than a single feature.

• Lead the architecture and design of complex, large-scale distributed systems • Design, develop, and maintain scalable, fault-tolerant microservices for both real-time and batch data processing; • Build and maintain high-performance REST APIs with a focus on scalability, reliability, and maintainability; • Design and implement data models and queries for efficient storage and retrieval across SQL and NoSQL databases; • Lead data quality initiatives to ensure consistency, accuracy, and reliability of data across the platform; • Collaborate with cross-functional teams to translate platform requirements into effective technical solutions • Drive technical standards and best practices for code quality, testing, and observability across engineering teams; • Mentor and provide technical guidance to engineers through code reviews, design discussions, and direct support • Take end-to-end ownership of the software development lifecycle, including deployment, monitoring, and incident response.

• Design, build, and maintain backend systems and APIs that power Wikidata’s query infrastructure • Improve reliability, observability, and automation of the Wikidata Query Service and data pipelines • Integrate Wikidata Platform services with other systems and data sources across Wikimedia • Collaborate with SRE, data engineers, and product teams to ensure stability and scalability under growing usage • Monitor production systems, respond to operational incidents, and proactively identify and resolve bottlenecks • Support platform migrations and system upgrades • Contribute to deployment automation, CI/CD workflows, and service instrumentation • Participate in code reviews, design discussions, and technical planning • Document systems and share knowledge with team members and Wikimedia’s broader technical community
