Software Developer jobs in London, ON

Position Summary

Vertical Motion builds and supports custom software for clients and develops AI-enabled products and engineering tools. This senior role focuses on AI engineering, application and agent security, cloud and container infrastructure, and harness development: the software that gives AI agents context, tools, execution environments and reliable feedback. The position owns architecture, implementation, testing, deployment and ongoing operation, while contributing to the maintenance and modernization of client production systems.

The position carries two ongoing mandates:

• AI engineering and platform ownership. Lead the development of secure AI-enabled software, agent harnesses and supporting infrastructure, with accountability for reliability, maintainability and measurable results.
• Client delivery and technical continuity. Deliver complete features within client development teams and maintain established production systems, preserving business rules, integrations and security boundaries as those systems evolve.

The role works directly with company leadership, client stakeholders, client in-house developers and QA.

Core Competencies and Supporting Capabilities

Business Need and Technical Continuity

Vertical Motion needs senior technical ownership across AI-enabled products, internal engineering tools and established client applications. This role develops new capabilities while keeping existing systems secure, dependable and maintainable.

The central requirement is the ability to connect AI engineering, security, infrastructure and harness development within working production software. Candidates must be able to assess technical tradeoffs, investigate failures and carry changes through implementation, testing, deployment and support.

Responsibilities overlap across several areas:

• AI features depend on reliable context, service integrations, validated outputs and measurable evaluation.
• Agent execution requires secure identity, controlled tool access, isolated environments and operational monitoring.
• Automation requires repeatable testing and independent verification before generated outputs are adopted.
• Shared information requires trustworthy synchronization, version history, conflict handling and recovery.
• Client delivery requires coordinated changes across data, APIs, interfaces, permissions, background processing, integrations and release workflows.

Broad technical ownership maintains architectural, security and operational continuity. Specialist experience with individual frameworks, client domains and device technologies supports that ownership and is treated as an asset rather than a separate core competency.

Main Duties and Responsibilities

General Responsibilities

• Research, evaluate and select technologies and architectural approaches for new and existing systems.
• Translate business and user requirements into technical specifications.
• Design system, data, integration and security architectures for web, mobile, desktop and cloud applications.
• Develop, test and document software, and coordinate implementation, integration and deployment with company staff, clients and client developers.
• Assess, troubleshoot, upgrade and maintain production applications, and resolve production incidents.
• When necessary, guide and mentor other developers through training material, reference implementations and coding standards.

1. AI Engineering and Harness Development

• Architect, develop and maintain production AI-enabled applications and agent harnesses, including the services, interfaces and execution controls needed to support dependable automation.
• Design model-agnostic integrations so AI providers and underlying models can evolve without substantial application redesign.
• Build context management and grounding capabilities that give agents relevant, authorized information while preserving source attribution and data boundaries.
• Develop secure agent-to-tool and agent-to-service integrations using Model Context Protocol (MCP) or equivalent interfaces, preserving the requesting user's permissions.
• Build orchestration and runtime controls for agent tasks, including environment provisioning, tool execution, task state, cancellation and failure recovery.
• Apply identity, access and execution policies throughout agent workflows, including appropriate human approval before sensitive operations.
• Maintain controlled AI toolchains through version management, integrity verification, reproducible environments and documented update policies.
• Develop AI-assisted test generation and validation. Adopt generated regression tests only after repeated independent execution demonstrates reliability.
• Integrate automated application security testing with explicit authorization and environment safeguards. Require approval for active scans, restrict them to authorized non-production environments, protect sensitive diagnostic data and track findings through resolution. Automated testing complements external manual penetration testing.
• Develop dependable data and file synchronization with change detection, version history, concurrency control, conflict handling, recovery and user or agent attribution.
• Build diagnostic and feedback tooling that captures sufficient application context to investigate defects while redacting sensitive information.

2. Software Intelligence and Supply Chain Security

• Develop maintainable software analysis services and interfaces using suitable backend frameworks, relational or graph data models and modern web technologies.
• Build source parsing, indexing, search and dependency analysis capabilities across multiple languages and software ecosystems.
• Integrate dependency inventory and vulnerability management tools, using package manifests and lock files to identify installed versions and maintain consistent findings.
• Generate and process Software Bills of Materials (SBOMs) using established standards, and integrate dependency analysis into repository and CI/CD workflows.
• Develop grounded AI-assisted code review, reporting and software analysis workflows through repository APIs, webhooks and other controlled integrations.
• Apply schema validation, prompt-injection defenses, protection against unintended network or resource access, and rate limiting to AI integrations.
• Design measured experiments to evaluate AI and code-analysis approaches, document results and determine their suitability for production use.

3. Client System Development and Support

Work alongside Vertical Motion developers, client stakeholders and client development teams. Own complete features from requirements through data design, APIs, interfaces, permissions, background processing, deployment and post-release support. Apply the following capabilities across assigned systems:

• Develop reliable business applications that manage operational records, reporting and external service integrations.
• Implement secure multi-tenant workflows, document processing, approval processes and concurrency controls.
• Translate review, assessment and certification requirements into maintainable workflows with appropriate notifications and auditability.
• Support subscription-based applications, identity integration, payment processing, localized interfaces and associated mobile functionality.
