Senior Backend Engineer
First seen by Alion on Aug 24, 2026.
Job Description :
Help build the backend systems that turn complex foodservice information and rules into trusted operational behaviour. This is a senior hands-on TypeScript/Node.js backend role in the current NestJS environment, with responsibility for consequential product behaviour from requirement interpretation through production.
Roles & Responsibilities :
- Build and maintain backend services and product capabilities in TypeScript on the Node.js runtime.
- Work in the established NestJS backend environment and apply its modular service patterns appropriately.
- Own substantial backend work from requirement interpretation through implementation, testing, release, production support and improvement.
- Implement interconnected rules, calculations, validation and state behaviour across costing, nutrition, allergens, supplier-product relationships, menus, procurement, compliance and related capabilities.
- Design and maintain production APIs, request/response contracts, validation, error behaviour, authentication/authorisation and service integrations.
- Work with relational schemas, constraints, joins, transactions, indexes, migrations, query behaviour and performance.
- Use caching, background jobs, queues or event-driven processing where appropriate, including failure handling, retries and recovery.
- Design proportionate automated tests that protect important rules, calculations, workflows and integrations from regression.
- Use evidence to diagnose production defects, performance issues and reliability problems, and document implementation behaviour and significant technical decisions clearly.
- Work with Product, analysis, frontend engineering, data/ML specialists and domain experts to understand the problem before implementing the solution.
Preferred Candidate Profile :
- Strong recent hands-on production backend engineering with TypeScript and Node.js; years of experience are not a standalone eligibility gate.
- Evidence of independently owning substantial backend features, services or systems in production.
- Ability to implement complex business/domain logic accurately, including rules, calculations, validation, workflows or state transitions.
- Strong relational-database engineering, including schema/integrity, transactions, queries and performance reasoning.
- Strong production API/integration engineering, automated testing, debugging and reliability thinking.
- Clear written technical communication and the ability to work from structured requirements and specifications.
- Experience with a structured backend framework. Direct NestJS is strongly desirable; credible TypeScript/Node.js framework transfer may be considered under the current proposed campaign treatment.
- Able to work on-site in Hyderabad, Monday-Friday. Relocation is permitted, but no relocation support is provided.
Tech Stack :
- Substantial production NestJS experience.
- Direct PostgreSQL experience.
- Redis or Valkey, queues, background processing or event-driven systems.
- AWS or comparable cloud delivery experience.
- MikroORM or another mature ORM.
