**About the Role** We are looking for a **Technical Lead** to drive end\-to\-end application engineering for a large\-scale marketing analytics platform, serving as the primary owner of code quality and application architecture. You will lead the design and deployment of containerized **Python** and **React** applications, integrate complex business logic and AI\-powered features into an existing platform, collaborate closely with DevOps teams, and guide senior engineers while ensuring alignment with established engineering standards and long\-term maintainability. **What you will do** * Review all PRs and enforce code quality standards, preventing "spaghetti code" and scope creep. * Design and deploy containerized applications using REST APIs. * Embed complex logic, AI features, and outputs from data\-heavy backends into the platform without disrupting existing workflows. * Working knowledge of the client's data stack (S3\-backed data lake queried via Athena, EKS/Kubernetes) and of how orchestrated pipelines feed the application — enough to collaborate with DevOps and clarify functional/non\-functional requirements, without owning the analytical pipeline architecture directly. * Understand how orchestrated data pipelines feed the application and help define functional and non\-functional requirements. * Lead senior developers and ensure adherence to engineering best practices and client standards. **Must haves** * **7\+ years of full\-stack engineering experience** with proven architectural ownership. * Strong production experience with **Python** using **FastAPI** or **Flask** . * Solid experience with **TypeScript** and **React** ; knowledge of Next.js or modern state management is a plus. * Experience designing and working with **REST APIs** , including migration from legacy GraphQL endpoints. * Hands\-on experience with **Docker** and **PostgreSQL** , including database migrations. * Demonstrated experience building or maintaining data\-heavy applications (large payloads/datasets, performance\-sensitive queries at the application layer). * Working familiarity with object\-storage\-backed data lakes and serverless query engines (S3 \+ Athena or equivalent) and with EKS/Kubernetes concepts — enough to drive DevOps conversations and reason about how data reaches the application. Hands\-on pipeline design not required. * Task orchestration awareness: familiar with what a DAG\-based orchestrator like Airflow does, or able to pick it up quickly from experience with a comparable engine. Won't be managing Airflow itself. * Strong command\-line proficiency in Mac/Linux environments using Bash and Makefiles. * Practical, hands\-on use of AI\-assisted development tools (e.g., Claude Code), paired with the critical judgment to challenge AI output when it compromises long\-term maintainability — including the leadership presence to set the standard for how the team uses AI tooling responsibly (e.g., flagging risky AI\-driven shortcuts during PR review). * Strong soft skills: the ability to hold and defend a technical opinion — challenging a stakeholder's or a tool's proposed "quick fix" with sound reasoning in pursuit of a solution that scales and is maintainable long\-term, while still being pragmatic enough to ship. * Upper\-intermediate English level. **Nice to haves** * Production experience with Athena, S3\-based data lakes, or Airflow. * Experience building AI features using AWS Bedrock, LangChain, Pydantic AI, or similar technologies. * Experience with monorepo tooling such as Nx or modern package managers including Poetry, UV, or Yarn. * Experience with Redis or other NoSQL and caching technologies. * Exposure to OLAP\-style analytics tools (Trino/Presto, ClickHouse, SageMaker) as a plus, not a requirement. * Experience working with marketing data structures, campaign management APIs, or digital advertising metrics. **Perks and Benefits** * **Professional growth** Accelerate your professional journey with mentorship, TechTalks, and personalized growth roadmaps * **Competitive compensation** We match your ever\-growing skills, talent, and contributions with competitive USD\-based compensation and budgets for education, fitness, and team activities * **A selection of exciting projects** Join projects with modern solutions development and top\-tier clients that include Fortune 500 enterprises and leading product brands * **Flextime** Tailor your schedule for an optimal work\-life balance, by having the options of working from home and going to the office – whatever makes you the happiest and most productive.
