You’ll contribute your expertise to architecture discussions, lead implementation of key projects, and mentor junior engineers in best practices.

What You’ll Do

• Design, develop, and maintain scalable microservices and APIs for real‑time biosensor data processing.
• Implement event‑driven integrations with messaging/streaming systems (Kafka, RabbitMQ) and analytics pipelines.
• Collaborate with SRE to ensure observability, performance, and operational excellence across backend services.
• Participate in architecture and design reviews, contributing to decisions on service boundaries, data models, and communication patterns.
• Optimize backend services for low latency, high throughput, and cost efficiency.
• Apply privacy‑by‑design and security standards in line with HIPAA/GDPR compliance requirements.
• Write clean, maintainable, and testable code; establish and uphold engineering standards within the team.
• Mentor junior engineers through code reviews, pair programming, and knowledge sharing sessions.
• Troubleshoot production issues and contribute to incident response and post‑mortem analysis.

Required Qualifications

• 5-8 years of backend engineering experience with distributed, cloud‑native systems.
• Strong skills in microservices architecture and API design (REST; familiarity with GraphQL/gRPC is a plus).
• Experience with Kubernetes in production environments and familiarity with service mesh concepts.
• Hands‑on proficiency with messaging/streaming systems such as Kafka or RabbitMQ.
• Programming expertise in backend languages such as Java, Kotlin, Python.
• Knowledge of secure coding practices and compliance requirements (HIPAA, GDPR, or similar).
• Solid understanding of performance optimization, scalability patterns, and async data processing.
• Strong collaboration and communication skills; ability to work cross‑functionally with other engineering and product teams.

Preferred Qualifications

• Experience integrating backend services with analytics and machine learning pipelines.
• Exposure to API gateways, authentication/authorization patterns, and rate limiting strategies.
• Background in digital health, IoT, or other mission‑critical platforms.
• Familiarity with cloud platforms (Azure/AWS/GCP) and infrastructure‑as‑code tooling (Terraform, Helm).

LINGO CULTURE

Customer‑first, quality‑driven, growth‑minded, and united. As a Senior Backend Engineer, you’ll contribute directly to delivering secure, reliable, and scalable features, helping teams ship innovative health technology quickly and with confidence.
