About the Team
Maestro Pulsar is a mission-critical, globally deployed platform supporting distributed service orchestration, connectivity management, and operational control across a complex ecosystem of internal services and external integrations.
The platform runs across multi-region (East/West) Azure, with zone-redundant regional gateways, global traffic steering, and both public and private connectivity paths. Reliability, correctness, and operational readiness are first-class concerns.
About the Role
We are looking for a Senior Software Developer who combines strong hands-on engineering skills with the ability to own complex technical problem spaces end to end.
This role goes beyond feature delivery. You will:
Own the design and evolution of critical services
Translate architectural direction and product intent into robust, production-ready implementations
Influence service contracts, resiliency patterns, and operational standards
Provide technical leadership and continuity for a long-lived platform
You will work closely with Software Architects, Product Owners, SRE/Operations, and Security, contributing to upstream design decisions while remaining accountable for high-quality execution.

Key Responsibilities:
•

1) Service Design & Development
• Design, develop, and maintain Java-based services within a distributed, event-driven architecture.
• Own service behavior end to end: APIs, workflows, persistence, failure handling, and operational characteristics.
• Design and evolve service interfaces and contracts (REST, gRPC, async messaging) with attention to:
• Versioning and backward compatibility
• Error models and idempotency
• Timeout, retry, and failure semantics
• Ensure implementations align with platform architecture patterns while remaining pragmatic and operable.
2) Technical Ownership & Collaboration
• Partner with Software Architects to translate architectural patterns into concrete, implementable designs.
• Work with Product Owners to refine features into well-scoped, engineering-ready work with clear acceptance criteria.
• Act as a technical point of contact for your services, supporting design discussions, reviews, and cross-team alignment.
• Contribute to architecture and design reviews, identifying risks, gaps, and improvement opportunities.
3) Resiliency & Production Readiness
• Build services that are production-ready by design, including:
• Health checks, graceful degradation, and recovery behavior
• Observability (logs, metrics, traces) aligned to SLIs/SLOs
• Capacity and performance considerations
• Participate in multi-region resiliency design and validation:
• Failover and failback behavior
• Automation guardrails and operational runbooks
• Readiness drills and post-incident improvements
• Collaborate with SRE/Operations to ensure operational requirements are addressed before production release.
4) Quality, Standards & Mentorship
• Uphold high engineering standards for code quality, testing, documentation, and maintainability.
• Contribute to shared service patterns and best practices across the platform.
• Mentor and support other developers through design reviews, code reviews, and technical guidance.
• Help reduce long-term platform risk by addressing technical debt and systemic issues.

Required Qualifications:
• 5+ years of experience in software development for complex, distributed systems.
• Strong hands-on experience with Matlab, Java, Python and modern backend development practices.
• Proven experience building and operating highly available, fault-tolerant services in production.
• Solid understanding of distributed systems concepts: microservices, event-driven architectures, API gateways, messaging systems.
• Experience defining and implementing non-functional requirements (availability, resiliency, scalability, security).
• Strong communication skills and the ability to work effectively across engineering, architecture, and operations.

Strongly Preferred Qualifications:
• Experience with cloud-hosted platforms (Azure preferred), including networking and identity concepts.
• Exposure to multi-region deployments, failover strategies, and disaster recovery.
• Familiarity with observability practices (SLIs/SLOs, monitoring, alerting).
• Background in mission-critical, telecom, networking, or control-plane systems.
