Job description

Senior Backend Engineer (AWS Systems & Infrastructure)

We are looking for a Senior Backend Engineer to take End-to-End Ownership of our backend systems for a mission-critical Regulatory Licensing Platform. You will be a key technical pillar on a lean, high-impact product team building application processing systems within a Highly Restricted Government Cloud Environment.

This role demands a "Systems-First" mindset. You won't just write code; you will own the entire lifecycle of your work - from architectural design, development to "Day 2" operational support, comprehensive monitoring, and infrastructure stability. We need someone who can translate complex compliance requirements into stable, production-ready reality without heavy oversight.

CORE EXPECTATIONS & RESPONSIBILITIES

• End-to-End Ownership & Autonomy: Own backend systems from greenfield development through to production. Navigate technical ambiguity independently, proactively identifying blockers and driving implementations to completion without needing constant direction.
• Systems-Led Backend Development: Develop resilient APIs using Node.js/TypeScript and PostgreSQL, designed for Just-in-Time (JIT) data access. You are responsible for writing comprehensive tests and ensuring all data is encrypted at rest and in transit.
• Infrastructure Support & Proficiency: Take operational responsibility for self-hosted components (EC2, EKS). Automate patching, hardening, and recovery, and manage secure transport protocols (SFTP/SSH).
• Cloud Infrastructure & Networking: Build and maintain multi-zone logical segmentation (Edge, Integration, App, and Vault). This includes managing virtual networking (VPC), IAM policies, and secure communication patterns.
• SaaS & Service Integration: Own the integration of critical third-party and central services (e.g., secure file-transfer gateways and notification engines). You ensure these "handshakes" are reliable, automated, and strictly auditable.
• Observability & Reliability Mindset: Design and implement a robust monitoring plane (CloudWatch, etc.). Define metrics, set up distributed tracing, and configure proactive alerting to catch issues before they impact users.
• Infrastructure-as-Code (IaC): Ensure every resource is auditable and reproducible using Terraform / AWS CDK, adhering strictly to "Policy-as-Code".

WHAT WE ARE LOOKING FOR

• 6/7+ years of Backend Engineering Experience: A proven track record of building, deploying, and maintaining complex, production-grade systems independently.
• Demonstrated Independence: Proven track record of building, deploying, and maintaining complex, production-grade systems independently.
• Cloud Infrastructure Fluency (AWS preferred): Deep, hands-on experience with cloud-native architectures, specifically networking (VPC), identity management (IAM), and secure data patterns.
• Technical Stack Mastery: Proficiency in Node.js/TypeScript and relational database design (PostgreSQL).
• Systems & OS Knowledge: Strong proficiency in Linux administration and container orchestration (Docker/Kubernetes). You understand the "plumbing" of how code runs on a server.
• Communication: Ability to explain complex technical trade-offs to non-technical stakeholders (PMs/Designers/Business Owners) clearly and concisely.
• Collaborative and low-ego - you care about the team succeeding, not just yourself.
