ROLE INTRODUCTION
On the lookout for a Lead Backend Developer to join Trainerize powered by ABC Fitness Solutions (www.trainerize.com). ABC Fitness Solutions builds comprehensive, scalable technology and software designed to manage and grow fitness businesses of all sizes. We need a Lead Backend Developer to design APIs and data layers, improve performance and reliability, and grow the backend practice - including code review, standards, and mentoring.
You will lead through technical direction, influence, code quality, mentoring, and cross-functional partnership — not through people management.
If that vision excites you, this is where it gets built. You'll spend your days on the high-volume APIs that power fitness experiences for millions, in an environment where AI agents are part of how you think, build, and review. Every feature you ship and every standard you set helps prove that AI-native engineering isn't a side project here - it's how we build.
RESPONSIBILITIES:
Design, develop, test, and document software for existing and new products
Build, maintain, and optimize .NET backend services (ASP.NET Core, REST APIs) and related data access
Own and evolve the backend architecture for our products, including RESTful APIs and Microsoft SQL Server (schema, queries, performance)
Own API strategy: set standards for design, versioning, security, and cross-team contracts, including third-party integration surfaces
Establish and uphold team practices and guardrails for agentic-IDE development (Cursor or similar), including review standards for agent-generated code
Partner with frontend (web and mobile), product, and design to define APIs and deliver cohesive, high-quality features
Work with DevOps on builds, releases, patching, and operational readiness
Review code, handle merge requests, and help keep code quality, structure, and automation (testing, CI/CD) at a high bar
Identify bottlenecks, debug production issues, and improve reliability and performance
Provide technical estimates and communicate progress and risks clearly
Lead and coach junior and intermediate developers; raise the bar through pairing and feedback
Improve engineering practices and processes (testing, observability, release discipline) in ways that fit the team
Share ownership of production health: monitor, respond to critical incidents, and drive fixes for instability or regressions
QUALIFICATIONS:
All applicants must be able to work from our Hyderabad office 2-3x a week
Bachelor's degree in computer science, software engineering, or related field (or equivalent industry experience)
6+ years of .NET experience and/or other object-oriented programming languages
Experience with Microsoft Visual Studio
Familiar with C#, WebAPIs, MVC, ASP.NET
Familiarity with a modern TypeScript / cloud-native SaaS stack
Deep RESTful API experience: owning API design, versioning, security, performance, and cross-team contracts at scale
Habitual use of an agentic coding IDE (Cursor or similar) and a track record of setting review standards for AI-generated code across a team
In-depth understanding of JavaScript programming and familiar with ES6
Work effectively in a cloud-based environment; experience with AWS is a strong plus
Familiar with object-oriented design patterns
Familiar with RESTful APIs
Experience with MS SQL Server and T-SQL language
Understanding of SQL best practices and methodologies and experience investigating and solving SQL performance issues
Proficient understanding of code versioning tools such as Git and the associated best practices
Familiarity with Agile methodologies and experience with leading a scrum team
AND IT’S GREAT TO HAVE:
Prior exposure to fitness/wellness products, multi-tenant SaaS, high-traffic APIs, or cloud-native tooling (containers, observability) - tell us what you've built or scaled
Experience designing and operating third-party API integrations at scale
General familiarity with a modern TypeScript / cloud-native SaaS stack is a plus
WHAT’S IN IT FOR YOU:
Purpose led company with a Values focused culture – Best Life, One Team, Growth Mindset
Time Off – competitive PTO plans with 15 Earned accrued leave, 12 days Sick leave, and 12 days Casual leave per year
11 Holidays plus 4 Days of Disconnect – once a quarter, we take a collective breather and enjoy a day off together around the globe. #oneteam
