Senior / Staff Software Engineer – Backend Engineering

Experience: 7+ years

Location: India

Role Type: Individual Contributor | Hands-on Engineering

About the Role

Oddr is looking for a deeply hands-on Senior / Staff Software Engineer who combines strong backend engineering fundamentals with an AI-first way of building software.

This is not a traditional development role where AI is used only for code completion. We are looking for engineers who can understand a problem, design the right solution, define architectural and security guardrails, and then use AI aggressively to accelerate implementation without compromising quality.

You will be expected to code regularly, own solutions end-to-end, build POCs, drive technical design, review critical code, and help raise the engineering bar across the team.

This is not a people-management role.

What You’ll Do

• Design and build scalable, secure backend systems using C# / .NET.
• Own features from problem definition and architecture through coding and production delivery.
• Use AI coding tools such as Claude Code, Codex, Cursor or GitHub Copilot to accelerate development.
• Define the right context, constraints, tests and guardrails around AI-generated code.
• Build POCs and evaluate technical approaches before scaling them into production.
• Drive system design, API design, data modelling and integration decisions.
• Review code for correctness, security, performance and maintainability.
• Build automated tests, observability and validation into the development lifecycle.
• Mentor engineers through technical reviews, pairing and architecture discussions.
• Identify opportunities to create reusable engineering patterns, automation, agents or developer tooling.

What We’re Looking For

• 7+ years of software engineering experience building production systems.
• Strong hands-on expertise in C# and .NET / .NET Core.
• Strong system design and architecture skills.
• Experience with distributed systems, APIs, databases, asynchronous processing and cloud-native applications.
• Good understanding of Azure, CI/CD, containers and modern software delivery practices.
• Strong debugging and problem-solving skills.
• Experience using AI coding tools as a meaningful part of day-to-day software engineering.
• Ability to critically review AI-generated code and identify architectural, security or quality issues.
• Strong understanding of software design, testing and engineering best practices.

Nice to Have

• Experience with React / TypeScript.
• Experience in legal-tech, fintech, billing, payments or enterprise SaaS.
• Exposure to AI agents, RAG, MCP or LLM-powered applications.
• Experience building reusable engineering platforms, tooling or automation.
• Familiarity with SOC 2, ISO 27001 or other security/compliance environments.

What Great Looks Like

You can take a complex problem from:

Problem → Design → POC → Architecture → Code → Validation → Production

You know when to rely on engineering judgment, when to challenge the AI, and when to use AI to dramatically accelerate execution.

At Oddr, we are looking for engineers who can think deeply, build quickly and ship safely.
