WHY JOIN US If you're looking for a place to grow, make an impact, and work with people who care, we'd love to meet you! ABOUT THE ROLE We are looking for a Technical Lead to drive end-to-end application engineering for a large-scale marketing analytics platform, acting as the primary gatekeeper for code quality and architecture as complex logic and AI features are embedded into an existing system.

You will review all PRs, design and deploy containerized Python and React applications via REST APIs, integrate data-heavy backends and AI feature outputs without disrupting existing workflows, and lead a team of senior developers aligned to client engineering standards.

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.

- Collaborate with DevOps on the client's AWS data stack, including an S3-backed data lake, Athena, and EKS/Kubernetes, and clarify functional and non-functional requirements.

- Guide senior developers and ensure alignment with the client's engineering practices.

- Lead end-to-end application engineering while maintaining high standards for architecture, scalability, and maintainability.

- Set standards for responsible use of AI-assisted development tools and identify risky AI-driven shortcuts during PR reviews.

MUST HAVES - 7+ years of full-stack engineering experience with a strong track record of architectural ownership.

- Strong production experience with Python, including FastAPI or Flask.

- Solid TypeScript/React experience.

- Experience with REST APIs, including migrating away from legacy GraphQL endpoints where needed.

- Hands-on experience with Docker and PostgreSQL, including database migrations.





- Experience building or maintaining data-heavy applications with large payloads or datasets and performance-sensitive application-layer queries.

- Working familiarity with AWS S3, Athena, and EKS/Kubernetes concepts, sufficient to drive DevOps conversations and understand how data reaches the application.

- Awareness of DAG-based task orchestration tools such as Airflow, or comparable orchestration engines.

- Strong experience working in Mac/Linux terminal-centric environments, including Bash and Makefiles.

- Practical, hands-on use of AI-assisted development tools such as Claude Code, with the critical judgment to assess AI-generated output and maintain long-term code quality.

- Strong technical communication and leadership skills, with the ability to defend technical decisions, challenge unsustainable quick fixes, and balance maintainability with pragmatic delivery.

- Upper-Intermediate English level.

NICE TO HAVES - Production experience with Athena, S3-based data lakes, or Airflow.

- Production experience implementing AI features using AWS Bedrock, LangChain, Pydantic AI, or similar technologies.

- Experience with monorepo tooling such as Nx or modern package managers such as Poetry, UV, or Yarn.

- Experience with NoSQL or caching layers such as Redis.

- Exposure to OLAP-style analytics tools such as Trino/Presto, ClickHouse, or SageMaker.

- Experience with marketing data structures, campaign management APIs, or digital advertising metrics.

PERKS AND BENEFITS - Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget - Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews - Flexibility: work 100% remotely with adaptable hours that support focus, autonomy, and a healthy work rhythm - Meaningful, modern projects:



build impactful products using modern technologies alongside global teams and leading brands - Collaborative culture: join a supportive environment with zero micromanagement where ideas are welcomed and contributions are recognized - Well-being & support: access local well-being programs and people-focused support tailored to your location

Developer
7+ years of full-stack engineering experience with a strong track record of architectural ownership.

Strong production experience with Python (FastAPI or Flask).

Solid TypeScript/React experience (Next.js or modern state management is a plus).

Comfortable with REST APIs, including migrating away from legacy GraphQL endpoints where needed.

Docker and relational databases (PostgreSQL), including comfort with database migrations.

Demonstrated experience building or maintaining data-heavy applications (large payloads/datasets, performance-sensitive queries at the application layer).

AWS Ecosystem: 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.

Highly comfortable in Mac/Linux terminal-centric environments (Bash, 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.
