Your Impact

As a Senior Software Engineer II on Dedrone’s Infrastructure Services team, you will design, build, and evolve the core systems that power both our developer platform and key backend services. You will combine strong software engineering fundamentals with deep infrastructure expertise to ensure our platform is scalable, reliable, and secure. This role goes beyond operating infrastructure—you will build production-grade backend services, design cloud-native systems, and own the CI/CD and runtime environments that support our product ecosystem. You will influence engineering standards, developer experience, and architectural direction across Dedrone’s product teams.

What You’ll Do

Work Location: This role is based out of our London office and follows a hybrid schedule. We rely on in-person collaboration and ask that team members work onsite Tuesdays through Fridays, with the flexibility to work remotely on Mondays, unless there is an approved workplace accommodation. We believe that connection fuels innovation, and our in-office culture is designed to foster meaningful teamwork, mentorship, and shared success.
Reports to: Engineering Manager, Infrastructure Services

Backend & Platform Service Engineering

Design, build, and maintain production-grade backend services (primarily Java, Go, or Python) that power deployment orchestration, internal APIs, and developer platform capabilities.
Contribute to architectural decisions including service boundaries, API design, persistence layers, scalability strategies, and fault tolerance.
Improve performance, reliability, and maintainability of platform-owned services through strong testing practices and thoughtful system design.
Maintain and evolve shared services owned by the Infrastructure Services team.

CI/CD & Developer Platform

Own, design, and optimize CI/CD systems supporting Dedrone’s distributed product ecosystem—reducing build times, deployment friction, and manual overhead.
Implement safe, automated deployment strategies (e.g., blue/green, canary, rollback automation) to increase deployment confidence.
Provide reusable templates, pipeline patterns, and tooling that improve self-service capabilities for product teams.

Cloud Infrastructure & Automation

Design and maintain scalable, secure AWS infrastructure using Infrastructure-as-Code (Terraform or AWS CDK).
Architect and optimize Docker images and container workflows; support orchestration platforms such as ECS, EKS, or Kubernetes.
Improve environment consistency, drift detection, and infrastructure reliability across staging and production systems.

Observability, Reliability & Security

Strengthen Dedrone’s observability stack—metrics, logging, tracing, alerting—leveraging tools such as Grafana and CloudWatch.
Use telemetry and SLO-driven insights to diagnose issues and proactively improve system reliability.
Contribute to security-focused improvements across CI/CD, IAM, secrets management, and cloud resource hardening.

Engineering Standards & Collaboration

Establish and promote high standards in service design, code quality, infrastructure patterns, and automation practices.
Partner closely with product engineering teams to reduce operational toil and increase developer velocity.
Collaborate with Axon platform, infrastructure, and security teams to align on shared best practices.

What You Bring

Relevant experience in backend engineering, platform engineering, developer infrastructure, or cloud-native software roles, with strong hands-on technical depth.
Proven experience building and operating production backend services with ownership of APIs, service reliability, and scalability.
Strong programming skills in at least one backend language (e.g., Java, Go, Python), with solid software engineering fundamentals.
Experience designing and supporting distributed systems, with understanding of concurrency, networking fundamentals, failure modes, and scaling patterns.
Deep familiarity with modern cloud environments (AWS preferred).
