About Role:

The Senior Python Developer will lead the design and implementation of ACL crawler connectors for Workato’s search platform. This role requires deep expertise in building scalable Python services, integrating with various SaaS APIs and designing robust data models. The developer will mentor junior team members and ensure that the solutions meet the technical and performance requirements outlined in the Statement of Work.

Key Responsibilities:

• Architecture and design: Translate business requirements into technical designs for ACL crawler connectors. Define data models, API interactions and modular components using the Workato SDK.
• Implementation: Build Python services to authenticate, enumerate domain entities and extract ACL information from OneDrive, ServiceNow, HubSpot and GitHub. Implement incremental sync, pagination, concurrency and caching.
• Performance optimisation: Profile code, parallelise API calls and utilise asynchronous programming to meet crawl time SLAs. Implement retry logic and error handling for network‑bound operations.
• Testing and code quality: Develop unit and integration tests, perform code reviews and enforce best practices (type hints, linting). Produce performance reports and documentation.
• Mentoring and collaboration: Guide junior developers, collaborate with QA, DevOps and product teams, and participate in design reviews and sprint planning.
• Hypercare support: Provide Level 2/3 support during the initial rollout, troubleshoot issues, implement minor enhancements and deliver knowledge transfer sessions.

Must Have Skills and Experiences:

• Bachelor’s degree in Computer Science or related field.
• 3-8 years of Python development experience, including asynchronous programming and API integration.
• Knowledge of python libraries-pandas,pytest,requests,asyncio
• Strong understanding of authentication protocols (OAuth 2.0, API keys) and access‑control models.
• Experience with integration with cloud or SaaS platforms such as Microsoft Graph, ServiceNow REST API, HubSpot API, GitHub API.
• Proven ability to lead projects and mentor other engineers.
• Excellent communication skills and ability to produce clear documentation.

Optional/Good to Have Skills and Experiences:

• Experience with integration with Microsoft Graph API, ServiceNow REST API, HubSpot API, GitHub API.
• Familiarity with the following libraries, tools and technologies will be advantageous-aiohttp,PyJWT,aiofiles / aiocache
• Experience with containerisation (Docker), CI/CD pipelines and Workato’s connector SDK is also considered a plus.

Our Mission

To make video as accessible to machines as text and voice are today.

At lookup, we believe the world's most valuable asset is trapped. Video is everywhere, but it's unsearchable—a black box of insight that no one can open or atleast open affordably. We’re changing that. We're building the search engine for the visual world, so anyone can find or do anything with video just by asking.

Text is queryable. Voice is transcribed. Video, the largest and richest data source of all, is still a black box. A computer can't understand it, and so its value remains trapped.

Our mission at lookup is to fix this.

About the Role

We are looking for founding Backend Engineers to build a highly performant, reliable, and scalable API platform that makes enterprise video knowledge readily available for video search, summarization, and natural‑language Q&A. You will partner closely with our ML team working on vision‑language models to productionize research and deliver fast, trustworthy APIs for customers.

Examples of technical challenges you will work on include: distributed video storage, a unified application framework and data model for indexing large video libraries, low‑latency clip retrieval, vector search at scale, and end‑to‑end build, test, deploy, and observability in cloud environments.

What You’ll Do:

• Design and build robust backend services and APIs (REST, gRPC) for vector search, video summarization, and video Q&A.
• Own API performance and reliability, including low‑latency retrieval, pagination, rate limiting, and backwards‑compatible versioning.
• Design schemas and tune queries in Postgres, and integrate with unstructured storage.
• Implement observability across metrics, logs, and traces. Set error budgets and SLOs.
• Write clear design docs and ship high‑quality, well‑tested code.
• Collaborate with ML engineers to integrate and productionize VLMs and retrieval pipelines.
• Take ownership of architecture from inception to production launch.

Who You Are:

• 3+ years of professional experience in backend development.
• Proven experience building and scaling polished WebSocket, gRPC, and REST APIs.
• Exposure to distributed systems and container orchestration (Docker and Kubernetes).
• Hands‑on experience with AWS.
• Strong knowledge of SQL (Postgres) and NoSQL (e.g., Cassandra), including schema design, query optimization, and scaling.
• Familiarity with our stack is a plus, but not mandatory: Python (FastAPI), Celery, Kafka, Postgres, Redis, Weaviate, React.
• Ability to diagnose complex issues, identify root causes, and implement effective fixes.
• Comfortable working in a fast‑paced startup environment.

Nice to have:

• Hands-on work with LLM agents, vector embeddings, or RAG applications.
• Building video streaming pipelines and storage systems at scale (FFmpeg, RTSP, WebRTC).
• Proficiency with modern frontend frameworks (React, TypeScript, Tailwind CSS) and responsive UI design.

Location & Culture

• Full-time, in-office role in Bangalore (we’re building fast and hands-on).
• Must be comfortable with a high-paced environment and collaboration across PST time zones for our US customers and investors.
• Expect startup speed — daily founder syncs, rapid design-to-prototype cycles, and a culture of deep ownership.

Why You’ll Love This Role

• Work on the frontier of video understanding and real-world AI — products that can redefine trust and automation.
• Build core APIs that make video queryable and power real customer use.
• Own systems end to end: performance, reliability, and developer experience.
• Work closely with founders and collaborate in person in Bangalore.
• Competitive salary with meaningful early equity.

💥 What will you do?

As a Lead Backend Engineer, you will

• Build out and help scale our Django (+ReactJS / VueJS) based web application as we add new features and customers

• Help us transition from monolithic system architecture to microservices and serverless system architecture to help meet our future scaling requirements

• Collaborate on a daily basis with a small, nimble team of product managers, engineers, and UX designers to understand business requirements and user experience goals and pain points.
• Build out features to enable multi-channel customer acquisition include partner channels, enterprise channels, and government channels
• Integrate third-party plugins to enhance customer experience and internal tooling build internal tooling to improve internal team efficiencies.
• Actively participate in code reviews
• Work with our quality assurance team to improve coverage on our automated testing suites

🙋 What are we looking for? 

While we do not have a strict list of requirements for candidates interested in this role, some indicators that you would fit this role and our engineering culture are 

• Prior experience of a few years (3+ years) with python based frameworks as Django or Flask would be essential to work on our application stack.

• You actively promote a culture of engineering excellence some of which could be writing efficient code, use of elegant design patterns, and styling your code through code-linting policies.

• You enjoy designing software architecture by collaborating with engineering managers, architects, and other lead engineers to explore existing systems, determining areas of complexity, potential risks to successful implementation.

• You enjoy coaching folks to achieve outcomes through nudges.

📢 Other information you may want to consider 

• We will be flexible for the rest of the pandemic and work remotely; however, we are not a remote-first company, and the work location would be Bangalore when things settle.
• Our backend tech stack includes Django, FastAPI, Postgres, Redis, Clickhouse, and TigerGraph. Our environments are managed through Docker, Kubernetes, and Terraform.

• You solve problems at their root, stepping back to understand the broader context.
• You develop pragmatic solutions and build flexible systems that balance engineering complexity and timely delivery, creating business impact.
• You understand a broad range of data structures and algorithms and apply them to deliver high-performing applications.
• You recognize and use design patterns to solve business problems.
