Sr. Software Engineer

Responsibilities:

• Design, develop, test, and deploy software solutions supporting large-scale telecom billing and customer service platforms.
• Diagnose and resolve complex, systemic, and unclear production issues across distributed components, APIs, databases, and middleware layers.
• Work effectively in ambiguous problem spaces, independently breaking down problems and driving solutions without prescriptive guidance.
• Design and improve systems built on distributed architectures, APIs, and microservices, with an understanding of failure modes and resilience patterns.
• Make informed engineering trade-offs (e. g., performance vs. maintainability and consistency vs. availability) aligned with business and operational needs.
• Contribute to system and design improvements using modern engineering frameworks, tools, and industry best practices.
• Collaborate with engineers, architects, and technical stakeholders to deliver scalable, reliable, and well-integrated solutions.
• Support technology strategy by evaluating current and emerging technologies in alignment with platform and business goals.
• Create and maintain technical documentation, including system designs, APIs, operational runbooks, and solution specifications.
• Provide production support, lead root cause analysis, and drive long-term fixes rather than short-term patches.
• Mentor team members through technical guidance, design discussions, and knowledge sharing.
• Perform other duties and projects assigned by business management.

Requirements:

• 4+ years of hands-on software engineering experience in enterprise or telecom environments.
• Strong proficiency in federated GraphQL and Java Spring Boot, with experience in large, business-critical production systems.
• Experience working with Oracle, MySQL, and MongoDB databases and SQL in high-volume, high-reliability systems.
• Solid understanding of distributed systems concepts, including APIs, microservices, concurrency, fault tolerance, and data consistency.
• Demonstrated ability to analyse and diagnose complex technical issues that span multiple systems or components.
• Proven experience working through ambiguity, independently defining problems, assumptions, and solutions.
• Understanding of architectural and operational trade-offs, including latency, throughput, availability, consistency, and maintainability.
• Experience with telecom billing platforms, customer service systems, or related domains (preferred).
• Familiarity with middleware and transaction-based systems such as Tuxedo (preferred).
• Strong analytical, problem-solving, and critical-thinking skills.
• Ability to communicate effectively and collaborate across engineering and technical stakeholder teams.
• Adaptability and resilience in fast-changing, high-impact environments.
• Customer-focused mindset with a commitment to delivering reliable, high-quality solutions.

Must Have Skills:

• GraphQL and Java Spring Boot software development.
• Oracle Database, MySQL, Mongo and SQL.
• DevOps: GitLab CI, Docker, Kubernetes, AWS.
• Practical use of AI-assisted development tools to improve code quality, productivity, and reliability: Claud AI.
• Problem-solving and debugging.
• Good to Have Skills: Tuxedo working knowledge.
