Description: Knowledge in: * 4 to 7 years of experience in web development for large-scale applications; * Mastery of .NET (C#) in advanced scenarios (concurrency, optimization, profiling); * Extensive experience with relational databases (preferably SQL Server): complex modeling, query tuning, indexes, locking & isolation; * Solid experience with MongoDB (advanced document modeling, performance, aggregations); * Experience designing scalable architectures (decoupling, context boundaries, integration between legacy systems and new services); * Strategic vision for evolutionary refactoring of critical systems without disrupting operations; * Experience with messaging systems (RabbitMQ, Kafka); * Strong focus on code quality (testability, maintainability, intentional simplicity); * Proficiency in automated testing (unit, integration, load, and/or contract tests) and use of quality metrics; * Excellent communication skills (clarity, objectivity, documentation of architectural decisions); * Experience mentoring Junior and Mid-level developers (guidance, structured feedback); * Strong willingness to understand business domains to influence solutions (high added value and reduction of accidental complexity). Expected Maturity * Ability to balance urgency and sustainable architecture; * Systemic thinking (end-to-end data flow, latency, resilience); * Data-driven decision-making based on metrics and business impact. Differentiators Knowledge in: * Advanced observability knowledge (OpenTelemetry); * Professional experience with Golang; * Experience with feature flags and gradual rollout strategies; * Prior involvement in defining technical roadmaps and architecture governance; * Experience designing platforms (multi-tenant, logical isolation, extensibility via plugins); * Knowledge of graph databases (Neo4j) for complex relationship scenarios. * Design and implement high-complexity, high-impact features; * Define and evolve architectures (services, modularization, scalability strategies, observability); * Lead structural refactors in legacy code focusing on stability and risk reduction; * Provide technical leadership to the team: pair programming, strategic PR reviews, dissemination of best practices; * Actively participate in performance analysis, cost optimization, and continuous improvements; * Analyze and resolve critical incidents (in-depth diagnosis, mitigation, long-term plans); * Support technical prioritization together with product teams (technical debt, risks, opportunities); * Elevate engineering standards (internal guidelines, automations, metrics). 2511200202481879779
