Backend Engineer

About Snapfix

Snapfix is on a mission to simplify the world's operations. We're building the world's most user-friendly platform for managing maintenance, inspections, and daily operations through photos, messages, and checklists. Our customers span hotels, facilities, and teams across the globe who rely on Snapfix to get things done, fast.

The Role

We're looking for a versatile Backend Engineer who's strong in PHP, Python, and Node and excited to build the technical foundations for AI-powered features. You'll improve and scale our existing systems while designing new services end-to-end. You'll collaborate across an international engineering team, mentor other engineers, and help set high standards for quality, reliability, and developer experience.

Responsibilities

• Own & evolve our backend: Improve performance, reliability, and maintainability of existing PHP and Python services (e.g. refactors, migrations, test coverage, resilience, cost/perf tuning).
• Build new services & APIs: Design, implement, and operate secure, well-documented REST endpoints and event-driven systems that our mobile and web apps love.
• Lay the AI foundations: Stand up data pipelines and storage for embeddings & retrieval (e.g. vector indices, feature stores). Build RAG pipelines, prompt/response evaluation, guardrails, and model-orchestration layers. Integrate hosted LLMs and/or self-hosted inference as appropriate, with observability and cost controls.
• Technical leadership: Lead projects, break down scope, make pragmatic build-vs-buy calls, and mentor engineers through reviews, pairing, and design docs.
• Quality & DevEx: Raise the bar on testing, CI/CD, observability, and documentation; champion secure-by-default patterns.
• Cross-functional collaboration: Partner with Product, Design, and Customer teams to ship clear, practical solutions that users adopt quickly.
• DevOps: Contribute to infra as code, containerization, and runtime operations alongside our platform team.

Experience and Skills

• 5+ years building and operating production backend systems.
• PHP and Node.js expertise and comfort picking new languages.
• Solid with relational databases (MySQL), caching (Redis), and queues/streams (e.g. SQS, Kafka).
• Proven ability to design clean APIs, data models, and service boundaries; familiarity with event-driven and asynchronous patterns.
• Hands-on with cloud platforms (AWS preferred), Docker, and CI/CD (e.g. GitHub Actions).
• Experience shipping AI-enabled features: LLM APIs, embeddings/vector stores, retrieval pipelines, prompt/tooling frameworks, evaluation/metrics.
• Strong fundamentals in testing, security, and privacy, plus practical monitoring/alerting (e.g. Datadog).
• Excellent written and verbal communication; comfortable collaborating across time zones and working async.
• Track record of mentoring or leading small squads.

Nice to have

• Kubernetes and Terraform; cost/performance optimization at scale.
• Domain knowledge in maintenance/facilities or mobile-centric workflows.
• Observability for ML/LLM systems (quality, latency, cost, safety).

Location: This role can be remote within India or based in Ahmedabad at Snapfix headquarters.
