Backend Engineer – Python / Rust / Go / AWS

Job Summary

We are seeking a strong Backend Engineer to join our engineering team and build scalable, high-performance backend systems on AWS. The ideal candidate is a hands-on software engineer with deep backend development experience, strong computer science and networking fundamentals, and experience working with Python and/or a statically typed language such as Rust or Go.

We are looking for someone who can go beyond simply using frameworks and tools — someone who understands how systems work under the hood, can make sound technical decisions, and is comfortable solving complex backend and distributed-systems problems.

The ideal candidate will have strong cloud experience, excellent programming fundamentals, and a track record of building and operating production systems at scale.

Responsibilities

• Design, build, and maintain scalable backend services and APIs running on AWS
• Develop production-grade software using Python, Rust, Go, or similar languages
• Build reliable, highly available, and fault-tolerant distributed systems
• Design and implement RESTful APIs and service-to-service integrations
• Work across application, infrastructure, and cloud layers to solve complex technical problems
• Diagnose and troubleshoot performance, networking, reliability, and production issues
• Make thoughtful architectural and technology decisions based on system requirements
• Develop automated tests and maintain high standards for code quality and reliability
• Contribute to CI/CD, observability, monitoring, and deployment processes
• Collaborate closely with other engineers, product teams, and technical stakeholders
• Participate in code reviews, system design discussions, and technical architecture decisions
• Continuously improve system scalability, performance, security, and operational reliability

Required Qualifications

• 4+ years of professional backend software engineering experience
• Strong hands-on experience developing production backend systems
• Strong programming experience with Python and/or Go/Rust
• Experience with at least one statically typed programming language such as Go, Rust, Java, C++, C#, or similar
• Strong understanding of fundamental computer science and software engineering concepts
• Strong understanding of networking fundamentals, including TCP/IP, HTTP, DNS, APIs, and related concepts
• Experience designing and building APIs and distributed backend services
• Hands-on experience deploying and operating applications in AWS
• Strong understanding of databases, data modeling, and backend performance
• Experience debugging complex production issues and working through problems independently
• Strong communication skills and the ability to clearly explain technical decisions and tradeoffs

Cloud & Infrastructure

• Strong hands-on AWS experience
• Experience with services such as ECS/EKS, Lambda, S3, RDS, DynamoDB, SQS/SNS, and CloudWatch
• Experience with Docker and Kubernetes
• Familiarity with infrastructure-as-code, preferably Terraform
• Experience with CI/CD pipelines and automated deployments
• Understanding of monitoring, logging, observability, and production operations

Preferred Qualifications

• Experience with both Python and a statically typed language, particularly Go or Rust
• Experience building high-scale, low-latency, or high-throughput systems
• Experience with distributed systems and microservices
• Experience with event-driven architectures and messaging systems
• Strong understanding of concurrency, parallelism, and asynchronous programming
• Experience working with Linux and cloud-native environments
• Experience in fintech, financial services, payments, trading, or another technically demanding environment
• Experience working with or evaluating modern AI/ML developer tools and APIs
• Demonstrated technical curiosity and ability to quickly learn new technologies

What We're Looking For

The strongest candidates will be true backend engineers, not simply developers who have worked with a particular set of tools.

We're particularly interested in engineers who:

• Have strong fundamentals in networking, systems, and software architecture
• Can explain the underlying concepts behind the technologies they use
• Have built and operated real production systems
• Have experience with both dynamically and statically typed languages
• Are comfortable going deep technically and troubleshooting problems from first principles
• Demonstrate genuine curiosity and hands-on engagement with new technologies
• Can communicate technical concepts clearly and effectively
