Development Specialist I (Backend - Focus on Scale and Architecture)

Responsibilities and Day-to-Day:

• Lead the evolution of Bling's distributed architecture, focusing on scalability, reliability, and simplicity.
• Define strategies for caching, messaging, and observability to ensure system resilience in high-volume scenarios.
• Design and validate technical solutions, ensuring alignment between business goals, performance, and software sustainability.
• Lead the AI strategy for productivity by implementing agents, assistants, and intelligent tools that accelerate development.
• Build PoCs (Proofs of Concept) to test and validate emerging technologies (LLMs, agent frameworks) before scaling them.
• Support CI/CD and Quality squads to accelerate deployments and strengthen automated testing pipelines.
• Promote Secure Coding practices, supporting teams from design through early vulnerability detection using AI.
• Mentor the engineering team, conducting architecture reviews and disseminating best practices in development and prompt engineering.

Mandatory Requirements (Must-have):

• Advanced experience in backend development (regardless of the source language).
• Hands-on experience with the use and integration of Generative AI (LLMs, agent orchestration, tool calling, RAG).
• Deep expertise in Microservices Architecture and high-availability systems.
• Practical experience with messaging and events (Kafka, RabbitMQ, or SQS).
• Experience with relational and non-relational databases in high-volume scenarios.
• Mindset focused on Scalability and Resilience (Design Patterns, SOLID, DDD).
• Openness and aptitude for working with Golang (it will be your primary tool).

Nice-to-have:

• Prior experience with Golang in production.
• Track record of creating internal development tools using AI.
• Track record of migrating monoliths to microservices.
• Knowledge of Chaos Engineering or FinOps.

Disqualifying Criteria (No-go):

• Engagement in own business or side activities.
• Lack of commitment to agreed-upon schedules and agendas.
• Difficulty organizing sprint tasks and reporting deliverables.
• Tendency to delegate priority tasks due to a lack of focus on the correct objectives.

Expected Competencies:

• Critical thinking
• Execution capability

Current Projects and Challenges:

The major challenge is ensuring system resilience in extremely high-volume scenarios, while leading the frontier of innovation by using AI for internal productivity and long-term architectural evolution.
