Senior Software Engineer (Architecture-Focused)

Hybrid — London

£70,000 - £80,000 + Benefits

We're partnering with a global adtech firm. They're now looking for a Senior Software Engineer with architectural exposure to help design and deliver key platform components while remaining hands-on across Python, TypeScript/React, and Google Cloud.

The Role

You'll play a hybrid role across system design, coding, and delivery, working closely with the CTO.

Expect a healthy mix of:

Architecture & Technical Direction

  • Contributing to the system design and technical roadmap for core scheduling and automation services
  • Helping define engineering standards across API design, data models, observability, and CI/CD
  • Supporting decisions on storage models, service boundaries, orchestration flows, and event-driven patterns

Hands-On Engineering

  • Building backend services in Python (APIs, async workflows, automation pipelines)
  • Developing UI components in React/TypeScript for internal tools and dashboards
  • Working in a GCP environment (Cloud Run, Cloud Functions, Pub/Sub, BigQuery, Firestore)
  • Optimising end-to-end performance of scheduling engines and workflow automation

Collaboration & Delivery

  • Working with Product, Content Ops, and channel teams to translate real-world workflows into scalable technical solutions
  • Reviewing code, supporting mid-level engineers, and contributing to release quality
  • Communicating trade-offs and technical decisions clearly to non-technical stakeholders

What You'll Bring

  • Strong backend experience with Python (APIs, async, production systems)
  • Solid React/TypeScript experience for dashboards or internal tools
  • Hands-on exposure to Google Cloud (Cloud Run, BigQuery, Pub/Sub, Firestore, etc.)
  • Experience building distributed or workflow-based systems (pipelines, schedulers, ETL, automations)
  • Ability to contribute to architectural discussions and improve system design
  • A pragmatic mindset: balancing engineering quality with delivery

Nice to Have

  • Experience with digital media, content workflows, or YouTube APIs
  • Familiarity with Airflow, Composer, Dagster, or Prefect
  • ML/AI awareness (classification, embeddings, tagging workflows)
  • Experience with high-throughput scheduling or rules engines
