Job description

About DataStealth

DataStealth is a single, unified data security platform (DSP) that discovers, classifies, and protects sensitive data across your entire environment, from on‑premise to legacy cloud to cloud. It protects data wherever it lives or flows, enabling security without complex integrations or changes to existing applications. By applying data protection strategies such as tokenization, it ensures that even if your perimeter is breached, the data remains unusable in the wrong hands.

About You

You’re a technically strong, systems‑minded developer who takes end‑to‑end ownership—designing, building, and operating production services in a fast‑moving scale‑up environment. With strong Java fundamentals and hands‑on Linux experience, you troubleshoot complex distributed systems issues and improve performance, reliability, and maintainability through thoughtful architecture and clean refactoring. You collaborate well across Engineering, Security, and customer‑facing teams, raise the bar through mentorship and documentation, and use AI‑assisted development tools as disciplined accelerators while maintaining rigorous review, testing, and production‑quality standards.

Role Overview

We are building the next generation of our platform and expanding our engineering team with polyglot developers who think in systems, not just features. You will work across our stack—designing, building, and operating high‑scale distributed services that protect some of the world’s most sensitive data. This is hands‑on, high‑impact work where your code ships to production and directly safeguards enterprises globally. Based in Mississauga with a hybrid schedule (4 days in‑office per week), you will join a collaborative, fast‑moving team where engineering ownership is real: you design it, you build it, you run it.

Key Responsibilities

• Design, develop, test, and operate cloud‑native microservices and platform components that form the backbone of the DataStealth DSP.
• Build and scale distributed systems that handle high‑throughput data discovery, classification, and protection across heterogeneous environments (cloud, hybrid, on‑premise, SaaS).
• Architect for resilience, observability, and performance—designing services that degrade gracefully, emit meaningful telemetry, and meet strict latency requirements.
• Work across the stack using the right language for the job: Java, TypeScript/Node.js, Golang, and Rust.
• Contribute to security products that implement tokenization, encryption, masking, and key management at enterprise scale.
• Apply secure coding practices, threat modeling, and DevSecOps principles as first‑class engineering concerns—not afterthoughts.
• Collaborate with security architects to ensure platform changes maintain compliance with PCI‑DSS, SOC 2, and other regulatory frameworks.
• Deploy and operate services across AWS, Azure, and GCP using infrastructure‑as‑code (Terraform, Pulumi, or CloudFormation).
• Design and manage CI/CD pipelines, container orchestration (Kubernetes/Docker), and observability stacks (Prometheus, Grafana, OpenTelemetry, ELK).
• Optimize cloud cost, performance, and reliability through data‑driven capacity planning and SRE practices.
• Practice agentic software engineering: use AI development tools (e.g., GitHub Copilot, Claude Code, Open Source AI coding tools) as disciplined engineering partners—directing agents to plan, write, and test code while maintaining full engineering ownership and judgment.
• Distinguish between rapid AI‑assisted prototyping and production‑grade agentic workflows; apply rigorous review, testing, and validation to all AI‑generated code before it reaches production.
• Contribute to the team’s AI‑augmented engineering practices: prompt engineering, context engineering, automated code review with AI, and AI‑assisted testing strategies.
• Participate in architecture discussions, design reviews, and technical decision‑making across squads.
• Mentor intermediate and junior developers, fostering a culture of continuous learning and engineering excellence.
• Maintain and improve technical documentation, runbooks, and onboarding materials.
• Work cross‑functionally with Product, Security, and Customer Success to translate complex requirements into well‑scoped engineering plans.

Required

• 3+ years of professional software development experience, ideally including work on security, infrastructure, or data‑intensive products.
• Track record of shipping production services and contributing to on‑call or incident response rotations.
• Experience with configuration‑as‑code (we use Groovy) and infrastructure‑as‑code tooling.
• Familiarity with observability practices (structured logging, distributed tracing, metrics).
• Proficiency in at least two of the following: Java (Must Have), TypeScript/Node.js, Golang, Rust—with demonstrated willingness and ability to learn the others.
• Experience designing and developing distributed systems, microservices, or platform‑level software.
• Solid understanding of cloud platforms (AWS, Azure, or GCP) including core services (compute, storage, networking, IAM).
• Hands‑on experience with Linux systems, shell scripting, and system‑level debugging.
• Strong grasp of networking fundamentals (HTTP/S, TLS, SSH, DNS, TCP/IP) and how they apply to distributed systems.
• Working knowledge of CI/CD pipelines, containerization (Docker), and orchestration (Kubernetes).
• Experience with agentic AI development tools (Copilot, Cursor, Claude Code, or similar) as part of a deliberate, quality‑driven engineering workflow—not as a substitute for understanding.
• Comfort working in a hybrid environment (Mississauga office, 4 days/week).

Nice to Have

• Experience with data security, encryption/cryptography, tokenization, or privacy‑enhancing technologies.
• Applying AI technologies and models to security domain problems.
• Contributions to open‑source projects in infrastructure, security, or developer tooling.
• Experience with event‑driven architectures (Kafka, RabbitMQ, NATS).
• Familiarity with database systems across paradigms (PostgreSQL, Redis, Elasticsearch, DynamoDB).
• Direct experience with performance analysis and profiling across polyglot systems (Java, Node.js, Go, Rust), utilizing platform‑specific tools to diagnose and resolve issues such as memory leaks, thread contention, and critical path latency in high‑throughput services.

Additional Information

DataStealth is an equal opportunity employer. We encourage applications from candidates of all backgrounds and experiences.

Candidates must be able to commute and work in our Mississauga office 4 days/week.
