About AHY Consulting

AHY Consulting is a technology consulting firm based in Thane, Maharashtra, building backend and AI-driven systems for clients internationally. Ambitious and senior team. No bureaucracy, real ownership, work that ships. The team carries over 20 years of industry engineering expertise, most of it spent on systems that have to survive real production load, not just a demo.

The Role

We're hiring a Senior Backend Developer to design and build systems that sit at the intersection of high-performance backend engineering and applied AI. This is not a CRUD API role. You'll architect services that handle concurrent processing, integrate LLMs and intelligent automation, and scale under real production load.

Full-time, on-site, based out of Kalyan Dombivli (Thane / Navi Mumbai).

What You'll Work On

Design and build backend systems and APIs that support complex, multi-stage processing pipelines

Write production Rust for performance-critical, concurrent and async workloads

Integrate LLMs and external AI/ML services (document intelligence, OCR, NLP, automation) into product workflows

Build and optimize search and data-processing pipelines at scale

Design and tune PostgreSQL schemas and queries for complex relational data

Own deployment: Docker, Linux production environments, CI/CD from commit to release

Implement security controls for systems that accept external user uploads and data

Diagnose and resolve production issues under pressure. You own it end to end

Collaborate with product and frontend teams, run code reviews, write technical documentation, and contribute to architecture decisions

Mentor less experienced developers and help refine engineering process

What We're Looking For

Strong foundation in computer science: data structures, algorithms, systems design

Hands-on experience with Rust in a real production system or a serious personal project, not just tutorials

Proven backend architecture experience. You've built systems more complex than one API talking to one database

Experience with async and concurrent programming

Practical experience integrating LLMs or AI/ML capabilities into applications

Solid PostgreSQL or relational database design and query optimization skills

Comfortable with Docker and Linux server administration and troubleshooting

Understanding of application security fundamentals, especially around file and document handling

Familiarity with microservices architecture, REST/GraphQL APIs, and both SQL and NoSQL database design

Exposure to cloud platforms and CI/CD pipelines for production-grade deployments

3-10 years of professional software development experience, ideally in high-traffic or production environments

Bachelor's degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience

Based in or willing to work on-site from Kalyan Dombivli / Thane / Navi Mumbai

Why AHY Consulting

Engineering-focused, senior team. Direct ownership, no layers of approval

Real systems-level and AI-integration work, not maintenance tickets

Fast decisions, fast shipping
