Rust
, with a strong focus on concurrent and distributed programming. - Lead technical design discussions
and contribute significantly to the architectural roadmap, emphasizing
event-driven architectures, microservices, and highly decoupled systems
on cloud-native patterns. - Optimise existing systems
for extreme performance, reliability, and cost-efficiency, identifying and resolving bottlenecks in high-throughput environments. - Build and maintain robust platform components
and internal tooling using technologies like
Crossplane for infrastructure management
and
Backstage for internal developer portals
, empowering other engineering teams. - Champion advanced DevOps and Site Reliability Engineering (SRE) practices
, including sophisticated CI/CD pipelines with
ArgoCD
, automated infrastructure provisioning with
Terraform
, and comprehensive observability (metrics, logging, tracing) using
Prometheus, Grafana, and OpenTelemetry
. - Collaborate closely with quantitative analysts, product managers, and other engineering teams
to translate complex business requirements into elegant, high-performance technical solutions. - Mentor and provide technical guidance
to junior and mid-level engineers, fostering a culture of continuous learning, code quality, and engineering best practices. - Proactively troubleshoot and resolve complex production issues, contributing to on-call rotations to maintain system uptime and performance SLAs.
What You'll Bring
- 6+ years of progressive hands-on experience
in backend software engineering, with a significant focus on building and scaling complex distributed systems in a senior or lead capacity. - Expert-level proficiency in Go (Golang) and/or Rust
for building high-performance, concurrent applications. - Deep understanding of distributed systems concepts
including consensus algorithms (e.g., Raft, Paxos), eventual consistency, and fault tolerance patterns. - Extensive experience with cloud platforms (AWS strongly preferred)
, including advanced services related to serverless computing (e.g., Lambda, Step Functions), managed databases (e.g., Aurora, DynamoDB), and messaging/streaming services (e.g., Kafka, Kinesis). - Proficiency with containerisation and orchestration technologies
like Docker and
Kubernetes
, including designing and deploying resilient applications on Kubernetes. - Strong knowledge of NoSQL databases
(e.g., Cassandra, MongoDB, Redis) and experience optimising data models for high throughput and low latency. - Proven track record of implementing and advocating for
GitOps principles
and
Infrastructure as Code (IaC)
. - Experience with Service Mesh technologies
like Istio or Linkerd is highly desirable. - Exceptional problem-solving skills
and the ability to diagnose and resolve complex technical issues in high-pressure production environments. - Excellent communication and interpersonal skills, capable of clearly articulating complex technical concepts to both technical and non-technical stakeholders.
- Relevant certifications (e.g., AWS Certified Advanced Networking - Specialty, Certified Kubernetes Application Developer (CKAD), Certified Kubernetes Administrator (CKA)) are a strong plus.
- Bachelor's or Master's degree in Computer Science, Engineering, or a related field is preferred.
