Senior Backend Engineer (Go/Python) - Remote | Immediate Joiners Only

We are seeking Senior Backend Engineers who thrive in agile, fast-moving teams and can turn bold ideas into impactful products. You will play a critical role in developing high-quality backend systems, solving complex problems independently, and shaping next-gen solutions that drive our company’s mission forward. You should excel in building scalable, performant systems and have a deep understanding of design and architecture patterns.

This role is for Immediately available BE Engineers only

What You’ll Do —

• The development of all server-side logic, definition, and maintenance of the central database, and ensuring high performance and responsiveness to requests from the front-end.
• Writing clean, high-quality, high-performance and maintainable code.
• The entire lifecycle of stories: development, test, production, and subsequent fixes and improvements.
• Solving complex technical problems.
• Develop a highly scalable and performant backend based on event driven architecture.
• Building robust, secure and scalable microservices.
• Splitting features into tasks and for the backend architecture and its evolution.
• Performing an objective analysis of the problem statement and coming up with an unbiased technical solution before writing a single line of code.
• Coordinating cross-functionally to ensure the project meets business objectives and compliance standards. This includes collaborating with QAs, PMs to ensure timely delivery of high-quality apps.
• Participating in, designing and driving the code review process.
• Implementing RESTful services with a metric-driven API Gateway.
• Ensuring sub-second server response and will be responsible to implement relational, document, key, object or graph data-stores, index stores and messaging stores as needed.
• Tracking defects and working with business owners and users to triage bugs and manage backlog.
• Taking ownership to run and maintain Cloud infrastructure.
• Evaluating relevant technologies, influencing and driving architecture and design discussions.
• Owning and delivering end-to-end backend features, ensuring high performance, reliability, and scalability.
• Collaborating with product stakeholders to deliver impactful solutions aligned with business objectives.
• Writing clean, efficient, maintainable code using best practices and participating in code reviews.
• Building reusable services and contributing to core engineering libraries.
• Documenting and demonstrating solutions through documentation, DFDs, and code comments.
• Solving complex technical problems with objectivity before writing code.
• Taking ownership of backend systems, including APIs, data pipelines, and infrastructure.
• Working closely with Product to help drive KPIs and align engineering goals with business outcomes.
• Staying agile and adapting quickly to evolving requirements, scope, and priorities.
• Own the inference tier for media: deliver low-latency scoring/ranking APIs; tune batching/concurrency/precision; design caching/back-pressure; enforce SLOs.
• Guarantee offline/online feature parity: feature storage, model versioning/registry, schema evolution, drift detection.
• Orchestrate GPU-heavy pipelines end-to-end (key-frames → model calls → stitching) with priorities, retries, checkpoints, and cost budgets.
• Run online evaluation safely: shadow → canary → A/B with metric guardrails and instant rollback.
• Build observability & reliability: tracing, metrics, logs, error budgets, kill-switches, privacy/rights compliance.
• Ship quality gates: lip-sync confidence scoring + fallback policy; scene-consistency checks before publish.

What You Bring —

• 3+ years of experience in software development with strong expertise in Golang.
• Overall 6+ years of experience in software development with a strong base and framework expertise in Java/Go/Python.
• Basic working knowledge of frontend technologies.

• Strong fundamentals in distributed systems, performance engineering, and API design.
• Proven experience taking ML models from notebook → production (packaging, serving, autoscaling, optimization).
• Fluency in feature lifecycle (contracts, versioning, offline/online parity) and model lifecycle (registry, rollout, rollback).
• Hands-on with orchestrating compute-intensive workflows and managing latency/cost trade-offs.
• Experimentation ops: canary/A-B design, metric plumbing, guardrails, revert discipline.
• Observability mindset: tracing, metrics, SLOs, incident runbooks.
• Plus (nice to have): familiarity with media processing, vector retrieval/embeddings, multilingual ASR/TTS.
• Security & compliance awareness: PII handling, rights metadata, audit trails.
