Sr. Specialist Software Engineer–.NET

FLX ONE Cargo | Location: Pune, India

Role Overview

FLX ONE Cargo is looking for an experienced Specialist Software to strengthen the core platform foundations that power our Cargo engineering organization. This is a senior, hands-on role for an engineer who can design, build, review, and troubleshoot platform-grade systems while also providing technical direction to the teams that depend on them.

You will own the shared services, libraries, and cloud-native foundations that allow delivery teams to move quickly without compromising scalability, reliability, or long-term maintainability. Beyond writing code, you will drive architecture discussions, raise engineering standards, and mentor engineers across the Cargo platform.

Key Responsibilities

Platform & Shared Services

• Design and build shared platform services used across Cargo engineering teams.
• Develop common libraries, frameworks, and runtime components that are modular, well-documented, and easy to consume.
• Take ownership of complex technical problems end-to-end, from design through production.

Cloud & Infrastructure Foundations

• Build and evolve cloud-native foundations, including deployment patterns, runtime configuration, and observability.
• Contribute to infrastructure-as-code practices and environment standardization.
• Improve reliability, performance, and operational consistency across services.

Architecture & Technical Execution

• Participate in and help drive technical design and architecture discussions.
• Translate architectural patterns into concrete platform implementations that enforce agreed boundaries, contracts, and standards.
• Evaluate technical trade-offs and recommend appropriate solutions.
• Identify and resolve cross-cutting technical debt, and flag scalability, reliability, security, and performance risks early.

Hands-On Engineering & Quality

• Own and evolve critical platform components in production.
• Write clean, testable, maintainable, and production-ready code.
• Perform deep code reviews on platform-facing changes and establish engineering best practices.
• Troubleshoot complex production issues and perform root-cause analysis.
• Support CI/CD, automated testing, monitoring, logging, and overall operational readiness.

Required Experience

• 12–16 years of overall hands-on software engineering experience.
• .NET: 10+ years of hands-on experience.
• .NET Core: 6+ years of experience.
• Cloud: 8+ years of experience with AWS or another major cloud platform (AWS preferred).
• RDBMS: 8+ years of experience with relational databases such as SQL Server, PostgreSQL, Oracle, or equivalent.
• React / JavaScript Framework: 5+ years of experience with React or another modern JavaScript framework.
• AIDLC – 1+ Years(Must)
• AI Tool – GitHub Copilot / Claude Code / Any equivalent AI Dev Tool(1+ years)
• AWS – 5+ Years
• Docker, K8s, ECS, Ansible, GitHub Actions, Jenkins – 5+ Years
• Should I have designed and own the E-E architecture of at least one major module in cloud
• Should be working as architect/Principle/Senior IC role

Note: Candidates should have genuine hands-on depth in the areas above rather than surface-level exposure; this is a senior technical role and experience levels will not be relaxed.

Must-Have Technical Skills

• Strong expertise in backend or platform engineering using modern enterprise stacks (.NET / .NET Core).
• Deep experience with cloud-native systems on AWS or an equivalent platform.
• Experience building shared services or internal platforms consumed by multiple teams.
• Strong understanding of object-oriented design, SOLID principles, design patterns, and clean architecture.
• Building and consuming RESTful APIs and distributed services.
• Database design, query optimization, indexing, transactions, and performance tuning.
• Front-end development using React or another modern JavaScript framework.
• Strong engineering judgment and system-level thinking.
• Working effectively with Product, QA, DevOps, Architecture, and other engineering teams.

Preferred Skills

• C++

Technical Leadership & Architecture Expectations

• Take ownership of complex technical problems from design through production.
• Participate in and drive technical design and architecture discussions.
• Evaluate technical trade-offs and recommend appropriate solutions.
• Mentor engineers and contribute to raising engineering standards across the team.
• Identify scalability, reliability, security, and performance risks early.
• Contribute to modernization and continuous improvement of the technology stack.
