We are looking for a Senior Backend Engineer with a strong background in building distributed, scalable, and high-performance backend systems. The ideal candidate has 6+ years of backend engineering experience, including 3+ years in microservices or distributed architecture, and deep expertise in Python, FastAPI, PostgreSQL, Redis, and async I/O patterns.

The candidate will own backend services end-to-end — from architecture and design to implementation, optimization, and production support — while working closely with cross-functional teams to deliver mission-critical systems.

Key Responsibilities

1. Backend Architecture & Development

• Architect, design, and implement backend services using Python (preferably FastAPI) with clean, maintainable, and scalable code.
• Develop microservice components, service communication layers, and distributed workflows.
• Build APIs and backend modules optimized for performance, fault tolerance, and low latency.

2. Distributed Systems & Scalability

• Design and maintain distributed systems capable of handling high throughput and large-scale operations.
• Implement inter-service communication patterns (REST, event-driven, message queues, pub/sub).
• Ensure system resiliency through redundancy, graceful degradation, and autoscaling strategies.

3. Asynchronous & Event-Driven Architecture

• Build async workflows, background tasks, and pipeline services leveraging asyncio or async frameworks.
• Develop event-driven components including producers, consumers, and event processors.
• Optimize I/O-heavy operations to maximize concurrency and throughput.

4. Data Storage, Pipelines & Caching

• Design relational schemas, write optimized SQL queries, and work with PostgreSQL performance tuning (indexes, partitions, query planning).
• Implement caching strategies, rate limiting, distributed locks, and session storage using Redis.
• Build data validation pipelines and compliance-driven data flows ensuring data correctness and auditability.

5. Security, Reliability & Observability

• Implement authentication, authorization, encryption, and secure API practices.
• Build monitoring, alerting, metrics, and tracing systems using modern observability tools.
• Diagnose production issues, identify bottlenecks, and drive long-term fixes and improvements.

6. Code Quality & Technical Leadership

• Conduct detailed code reviews and ensure engineering best practices across the team.
• Participate in technical roadmap planning, architectural discussions, and system design decisions.
• Mentor junior and mid-level engineers; drive a culture of technical excellence and ownership.

Required Qualifications

• 6+ years backend engineering experience.
• 3+ years building microservices or distributed systems.
• Strong expertise in Python and frameworks like FastAPI (or Flask/Django with async exposure).
• Deep understanding of async I/O, concurrency models, and asynchronous programming in Python.
• Strong experience with PostgreSQL (schema design, advanced queries, optimization).
• Hands-on experience with Redis for caching, queues, session management, and distributed patterns.
• Experience with event-driven architectures, message processing, or streaming systems.
• Solid understanding of system design, scalability principles, and API lifecycle management.
• Experience working with CI/CD pipelines, containerization (Docker), and cloud environments.

Product Engineer

Product Engineer | Fibr.ai

Bengaluru · In office · 2-6 years Stack: Python · FastAPI · Temporal · PostgreSQL · MongoDB

The role Fibr is building the agentic web experience layer - turning every URL into an intelligent agent that senses intent, makes decisions, and adapts in real time. Our agents personalise the full journey, running long LLM workflows against live customer accounts and millions of sessions.

You'll own features end-to-end - from the rough idea in a Slack thread to something shipped, instrumented, and behaving correctly in production. New surface areas land on your plate every few weeks: a new agent, a new integration, a new optimization loop. You're responsible for the whole thing, including the evals and metrics that prove it works. You'll work directly with the founding team and ship to real users every week.

What you'll do Ship AI-powered features end-to-end - backend, data, LLM layer, and the surface the user sees Design long-running workflows that hold up against rate limits, partial failures, and noisy third-party APIs Build and maintain the evals, guardrails, and instrumentation that decide whether a feature is good enough to ship Model the data behind agents and the analytics behind product decisions Sit in on architecture calls and shape where the platform goes next

Must-haves 2-6 years of production backend experience Has shipped LLM-powered features to real users in production - not demos, not side projects. Be ready to talk about what broke and how you fixed it Has built and run evals for LLM systems. Show us the harness, the dataset, and the decisions it drove Comfortable across relational and document databases Has worked with a durable workflow or queue system in production Ships fast without breaking the build Nice-to-haves RAG, vector stores, or tool-use / multi-step agents in production Experience with rate-limited third-party APIs at scale (ad platforms, CRMs, analytics) Strong product sense - you catch the UX issue before the user does Time spent at an early-stage startup

How we work High ownership, low bureaucracy. Decisions in the room, not in docs. You'll work directly with the founding team.
