Software Engineer - Golang (Senior - Mid)

📋 Description

• • Architect and deliver high-throughput, low-latency microservices in Go that power 2.2 billion daily API calls and 2 billion instant notifications across 450+ servers worldwide, directly influencing the experience of 25 % of global internet users.
• • Own the full SDLC of new features—from whiteboard sketches to production deployment—while collaborating with product managers, data scientists, and UX designers in cross-functional agile squads that release multiple times per day.
• • Design resilient RESTful and gRPC APIs that integrate seamlessly with our AI-driven CDP, ensuring sub-100 ms response times even under peak Black Friday traffic, and maintain backward compatibility for Fortune 500 clients like Samsung, Nike, and IKEA.
• • Optimize data pipelines that ingest and process 100 TB of historical behavioral data, leveraging AWS managed services (EKS, Lambda, Kinesis, SQS) to achieve horizontal scaling and cost efficiency without sacrificing data integrity.
• • Champion clean-code practices by writing expressive, test-driven Go modules with >80 % unit-test coverage, enforcing linting standards, and mentoring junior engineers through pair programming and in-depth code reviews.
• • Diagnose and resolve complex distributed-system issues using distributed tracing (OpenTelemetry), centralized logging (ELK), and real-time alerting (Grafana, PagerDuty) to maintain 99.9 % uptime SLAs for mission-critical campaigns.
• • Contribute to architectural decisions on caching strategies (Redis, Memcached), database sharding, and eventual-consistency models that reduce latency by 30 % and cut infrastructure costs by 20 % quarter-over-quarter.
• • Collaborate with DevOps to automate CI/CD pipelines in GitHub Actions and Argo CD, enabling one-click rollbacks, canary releases, and blue-green deployments that minimize customer impact during updates.
• • Drive continuous performance tuning by profiling Go services, optimizing GC behavior, and rewriting hot paths to shave milliseconds off user-facing endpoints, translating directly into higher conversion rates for global brands.
• • Participate in blameless post-mortems, translate lessons learned into actionable engineering OKRs, and evangelize best practices across 30 global offices to cultivate a culture of operational excellence and psychological safety.
• • Experiment with emerging technologies—such as WebAssembly at the edge or GraphQL federation—to keep Insiderone at the forefront of martech innovation and maintain our position as the #1 leader in all G2 categories.
• • Engage in internal guilds and Tech & Dev Talks to share knowledge on topics ranging from Go generics to AI model serving, influencing a community of 1,500 colleagues across 50 nationalities who are united by curiosity and impact.
