Lead the evaluation and adoption of new technologies, frameworks, and architectural patterns where they provide measurable value. Drive architectural consistency through technical reviews, design reviews, and collaboration across engineering teams. Mentor and coach engineers on software design, architecture, distributed systems, and engineering best practices. Promote a culture of technical excellence, innovation, continuous learning, and high-quality software engineering. Collaborate with engineering leadership, product managers, and other stakeholders to align technical strategy with business objectives. Communicate technical concepts, architectural decisions, trade-offs, and recommendations to both technical and non-technical audiences. Identify opportunities to leverage AI technologies, LLMs, RAGs, AI agents, and agentic systems to enhance products, development processes, and business outcomes. Requirements 10+ years of software engineering experience. 3+ years of software architecture experience, including designing distributed systems and leading technical direction across complex software projects. Proven experience designing, architecting, and evolving large-scale distributed systems and microservices-based platforms, with deep expertise in software design principles, architectural patterns, scalability, performance, reliability, and security. Strong hands-on development experience building enterprise-grade backend systems using technologies such as C#, Java, Python, PostgreSQL, Elasticsearch, REST APIs, event-driven architectures, and messaging platforms such as RabbitMQ, Kafka, NATS, or similar technologies. Demonstrated ability to lead technical design, architecture reviews, and complex cross-team initiatives, while influencing technical direction and driving alignment across engineering teams and stakeholders. Strong ability to evaluate emerging technologies, perform technical research, build proof-of-concepts, and translate business needs into scalable technical solutions. Practical experience designing and implementing AI-powered solutions, including hands-on experience with LLMs, RAGs, AI agents, agentic frameworks, MCP, orchestration frameworks, and modern AI application architectures. Excellent communication, mentoring, and collaboration skills, with the ability to effectively engage both technical and non-technical audiences. Fluency in English, both written and verbal.
