Backend Engineer - Oddr
About Oddr
Oddr is a modern enterprise platform purpose-built for professional services firms. We handle the financial nervous system of some of the world's most demanding clients - invoicing, payments, and revenue intelligence at scale. Our systems process high-stakes, high-volume financial workflows where correctness and reliability are non-negotiable. We're a small, senior-leaning team. Engineers here own systems end to-end, make real architectural decisions, and ship things that matter.
The Role
This is a deep, hands-on individual contributor role. You'll be working on the core backend platform - designing APIs, building scalable workflows, hardening infrastructure, and setting the technical bar for the team around you. You won't be managing people, but you'll naturally
raise everyone's game through code reviews, technical guidance, and the quality of your own work. If you thrive in environments with high ownership, low bureaucracy, and genuinely hard problems, this is the role for you.
What You'll Do
Core Platform Development
Design and build reliable, scalable backend systems using .NET Core. Architect RESTful APIs and business workflow orchestration that hold up under real enterprise load. Make considered tradeoffs between correctness, performance, and maintainability.
Cloud & Infrastructure
Own backend services on Microsoft Azure - app services, databases, messaging, storage, and access management. Work closely with DevOps to improve deployment pipelines and infrastructure reliability.
CI/CD & DevOps Collaboration
Support and improve CI/CD pipelines for fast, safe deployments. Bring a production-minded perspective to automation, rollback strategies, and release confidence.
Security & Compliance
Proactively embed security into the development process - secure coding practices, data protection, access controls, and compliance awareness relevant to enterprise financial systems.
Quality & Observability
Set standards for testing (unit, integration, e2e), code review, and observability. You should care deeply about knowing when things break before customers do.
Technical Mentorship
Unblock engineers around you. Share context, raise the quality of code reviews, and help the
team develop good engineering intuition - without needing a management title to do it.
What We're Looking For
Required
• 6 -10 years of backend engineering experience with strong depth in .NET Core.
• Solid understanding of RESTful API design, service architecture, and distributed systems.
• Strong relational database skills - schema design, query optimization, indexing (PostgreSQL or SQL Server)• Security-conscious mindset with practical experience applying secure coding practices
• Ability to operate independently in a fast-moving, ambiguous environment
Strong Plus
• Experience with multi-tenant SaaS architecture and tenant isolation patterns
• Hands-on experience with Microsoft Azure (App Services, SQL, Service Bus, Key Vault, etc.)
• Experience with CI/CD tooling and deployment automation
• Background in financial systems - payments, invoicing, reconciliation, audit trails
• Exposure to event-driven architecture, background job processing,and async workflows.
• Prior experience in a tech lead, staff engineer, or equivalent hands-on senior role.
What We Offer
• Competitive salary and benefits
• A small team where your decisions actually shape the product
• Hard problems worth solving - no ticket-factory work
• Flexibility and trust to get things done your way
