Lead Application Developer – Serverless Python / AWS / Lambda – Northern Ireland

Fully Remote

Salary: up to £150k+ Market-leading benefits package

About the Company

Our client is a high-growth, VC-backed Fin Ops technology company helping enterprises and MSPs optimize cloud costs across hybrid and multi-cloud environments. Over the past decade, they’ve evolved from bespoke cloud consulting to a platform-led approach — offering cost intelligence, ML-powered recommendations, and deep cloud integrations.

They are a founding member of the Fin Ops Foundation, a key voice in the emerging Bill Ops space, and are now scaling a next-gen cloud ROI platform — built from first principles to prioritise momentum, quality, and empathy.

As they expand globally, they’re investing in a best-in-class engineering team — starting with a core UK/Northern Ireland base.

The Opportunity

This is a strategic hire for a Lead Application Developer who will shape the technical foundation of a new cloud-native platform. You’ll join as one of the first engineers in the UK/Northern Ireland team, working directly with senior architects and distributed peers across the US and EMEA.

You'll lead by doing — designing and building serverless microservices, data-rich APIs, and resilient infrastructure that scales. This is a hands-on role that also offers long-term opportunities to grow into technical leadership as the team expands.

First Principles That Guide Us

• Our client has a bias for momentum over urgency. They build value by stacking repeatable wins — not just reacting.
• They inspect and interrupt inertia. They challenge the status quo when it slows them down.
• They disrupt and displace technical debt. They don't patch; we fix.
• They stack small successes. Progress comes from consistently delivering value.
• They lead with empathy. They support each other as humans first.

• Build and refine APIs (REST and Graph

QL) using App Sync, API Gateway, and Event Bridge

• Work with Dynamo

DB, Aurora Serverless, and S3 for cloud-native data solutions

• Collaborate with frontend (Vue.js) and data platform engineers (Snowflake, Airflow)

• Contribute to CI/CD pipelines, observability, and day-2 operational tooling

• Partner with product and architecture teams to translate customer needs into working systems

• Engage in cross-regional collaboration (US, EMEA, India) in a fully remote team

• 8–10+ years of backend development experience in cloud-first or SaaS environments

• Strong knowledge of AWS serverless architecture:
Lambda, API Gateway, Cognito, IAM, Dynamo

DB, S3

• Experience with event-driven design using SQS, SNS, Event Bridge

• Comfortable working in containerized and serverless contexts (12-factor apps)

• Hands-on experience with observability stacks: metrics, traces, logs

• Strong communicator able to interface confidently with both technical and non-technical audiences

Bonus Experience

• Familiarity with IaC frameworks (Cloud Formation, Terraform, SAM)

• Exposure to Snowflake, DBT, Airflow, or cost analytics/data pipeline tools

• Knowledge of Fin Ops practices or cost intelligence platforms

• Experience contributing to open-source platforms or cloud-native communities

• Working knowledge of ML or AI-led querying and optimization techniques

Why Join?

• Shape the early foundations of a new product engineering function in the UK

• Work directly with the platform architect and exec team on roadmap and design

• High trust, low-ego environment with global collaboration

• Backed by strategic acquisitions and solid funding — no technical debt baggage

• Remote-first culture with flexibility, autonomy, and meaningful ownership

• Clear career paths into architecture, team leadership or cross-functional roles
