About the project

We're working on an enterprise-scale Cyber Recovery Environment in AWS — built to protect critical workloads from ransomware and destructive attacks. Think highly isolated cloud architecture, immutable storage, fail-closed security, and automated access controls. Everything is scoped to NIST 800-53 Moderate, with a full audit-ready evidence package ready at go-live.

The role

You'll be the person who owns security controls — from design to validation to ongoing review — with everything implemented as code. It's a part-time engagement (~20 hrs/week) with a predictable twice-weekly review cadence covering infrastructure, IAM, encryption, and serverless automation. You'll work closely with GRC, SOC, and Cloud/DevOps teams, so communication matters as much as technical depth here.

What you'll be doing

• Designing and implementing security controls against NIST 800-53 Moderate — tailoring them to the environment and mapping inheritance across layers
• Running regular security reviews of Terraform and IaC changes, keeping a clean findings log and tracking remediations
• Reviewing and shaping IAM policies, SCPs, and access models across a multi-account AWS setup
• Designing and validating KMS encryption — key policies, rotation schedules, and cross-account access patterns
• Reviewing and improving serverless automation — replication windows, access controls, and security boundaries
• Making sure logging, monitoring, and threat detection are properly configured end-to-end
• Validating the fail-closed model — access restrictions, automated controls, and break-glass procedures
• Keeping the Control Traceability Matrix up to date and putting together audit evidence packages in immutable storage
• Supporting SIEM integration, tuning detection rules, writing runbooks, and helping internal teams get up to speed

What we're looking for

• 5+ years in AWS Security or DevSecOps engineering
• Solid, hands-on Terraform experience — you know what to look for in an IaC security review
• Real familiarity with NIST 800-53 Rev. 5 and what it actually takes to pass an audit
• Deep knowledge of IAM, Identity Center, SCPs, and multi-account AWS architecture
• Strong background in KMS and encryption design
• Hands-on with AWS security and monitoring services — logging, config, threat detection
• Experience validating automated, fail-closed security architectures
• Comfortable writing Python and/or Bash
• Clear communicator — you document things well and can explain security decisions to non-security people

Nice to have

• Cyber recovery / immutable storage
• S3 Object Lock
• Security Hub Macie · Inspector · Access Analyzer
• AWS Solutions Architect Pro / DevOps Pro
• SOC 2 · PCI-DSS · HIPAA
• SIEM integration experience

What AppRecode offers

• 20 days of paid annual leave plus public holidays.
• 5 paid sick days per year.
• Remote-first work environment.
• Friendly and supportive team culture.
• Personal development plans and access to experienced mentors and technical leaders.
• Reimbursement for sports activities and professional certifications (after probation).
• Ongoing learning opportunities: internal trainings and knowledge-sharing sessions.
• Free English classes if you want to further improve your communication skills.

Position Overview

We are looking for a highly skilled and versatile Full Stack Web Developer to join our engineering team. In this role, you will be responsible for designing, developing, and deploying scalable web applications from the ground up. You will bridge the gap between seamless user interfaces and robust backend architectures while leveraging modern cloud infrastructure and AI-assisted coding tools to accelerate the development lifecycle.

Key Responsibilities

• End-to-End Development: Design and build dynamic, responsive web applications using React on the frontend and Node.js on the backend, written entirely in TypeScript.
• API Design & Integration: Develop, maintain, and document robust RESTful and GraphQL APIs, ensuring efficient data fetching and seamless client-server communication.
• Database Management: Architect and manage both relational (SQL) and NoSQL databases, ensuring optimal data modeling, querying, and performance.
• Cloud Infrastructure: Deploy, maintain, and scale applications utilizing Amazon Web Services (AWS).
• AI-Enhanced Engineering: Utilize Claude Code by Anthropic to automate routine tasks, refactor legacy code, debug complex issues, and accelerate feature delivery via AI CLI workflows.
• Collaboration & Quality: Work closely with product managers and designers to translate requirements into technical solutions. Write clean, maintainable, strongly-typed, and well-tested code.

Required Skills & Qualifications

Core Languages & Frameworks
Front-end

• Strong proficiency in TypeScript across both the frontend and backend stack.
• Deep understanding of React core principles (Hooks, state management, component lifecycle, and Context API).
• Proven experience building scalable server-side applications using Node.js (Express.js, NestJS, or similar frameworks).

APIs & Data Fetching

• Hands-on experience designing, building, and consuming GraphQL APIs (e.g., Apollo Server/Client).
• Strong understanding of asynchronous programming and REST API design.

Databases

• Solid command of SQL (MySQL, etc.) including schema design, complex joins, and query optimization.
• Hands-on experience with Amazon DynamoDB, including designing single-table architectures, handling partition keys, and managing NoSQL data access patterns.

Cloud & DevOps

• Practical experience with the core AWS ecosystem (e.g., Lambda, API Gateway, S3, IAM).
• Familiarity with deploying full-stack applications in a cloud environment.

AI Tooling

• Experience using Claude Code by Anthropic (or similar advanced AI coding assistants/agents) to navigate codebases, generate boilerplate, run tests, and execute git workflows autonomously from the terminal.

Preferred Qualifications (Nice-to-Haves)

• Advanced AWS Services: Experience with AWS Cognito for secure user authentication and authorization.
• Serverless & IaC: Hands-on experience with AWS SAM (Serverless Application Model) and AWS CloudFormation for Infrastructure as Code and serverless deployments.
• CI/CD Pipelines: Experience configuring and maintaining continuous integration and continuous deployment pipelines, specifically using CircleCI.
• Containerization: Familiarity with Docker and container orchestration.
• Security: Strong understanding of modern web security practices (OAuth, JWT, CORS, Role-Based Access Control).
