About Aspeiro Technology Group

Aspeiro Technology Group specializes in technology driven remote monitoring and network technology services and is developing a new proprietary technology platform.

The product is currently under confidential development, so the full commercial proposition and technical architecture will be discussed with shortlisted candidates rather than published in this advertisement.

We are building technology intended to operate continuously, integrate with external systems, and make dependable decisions from real-time events and data. Security, reliability, traceability and sound engineering judgement are fundamental to the product.

The Opportunity

We are looking for a capable, hands-on Platform Software Engineer to join our engineering effort and take real ownership of backend services, integrations, infrastructure and production reliability.

This is a hands-on technical role, not a people-management position. You will personally design systems, write and review production code, solve integration problems, and help establish the technical foundations the product runs on.

You will work closely with the rest of the engineering team and directly with company leadership, with meaningful input into architecture, engineering practices, security and delivery.

The role will suit someone who enjoys hands-on development, solving difficult systems problems, and taking responsibility for outcomes. You should be comfortable being trusted to make decisions and deliver working software rather than operating within several layers of process.

What You'll Be Responsible For

• Designing and developing backend services, APIs and data models.
• Building event-driven and asynchronous processing workflows.
• Creating dependable workflow and state-management services.
• Developing secure integrations with external platforms and third-party APIs.
• Implementing queues, retries, timeouts, rate limits, deduplication and idempotent processing.
• Integrating AI and machine-learning services through secure, structured interfaces.
• Building clear, complete and auditable records of system decisions and actions.
• Improving tenant isolation, authentication, authorization and secrets management.
• Designing safe behavior for network, provider and third-party service outages.
• Developing automated tests, integration tests and simulation tools.
• Contributing to CI/CD, deployment, versioning and rollback processes.
• Implementing logging, metrics, alerting and production observability.
• Investigating production issues and improving system resilience.
• Reviewing code and contributing to engineering standards.
• Documenting architecture, integrations and operational procedures.
• Sharing technical knowledge and reducing dependencies on any one person.
• Working with company leadership to convert real-world requirements into dependable software.

What We're Looking For

• Solid full-stack engineering experience: comfortable in TypeScript/Node.js and React, and able to pick up a new part of a system without hand-holding.
• Real experience with a major cloud provider (we're on AWS: Lambda, Step Functions, EventBridge, DynamoDB) and relational databases (we run PostgreSQL with row-level security for tenant isolation).
• Experience with event-driven systems, message queues, or asynchronous, retry-safe and idempotent workflow design.
• Experience with secure software design, least-privilege access, and secrets management.
• Comfortable with infrastructure-as-code, git-based workflows, and writing your own design records and runbooks. Documentation isn't an afterthought here.
• Automated testing and production-quality code review as standard practice, not an extra step.
• Someone who is careful and precise by disposition, not just by process. This is a system where an unhandled edge case has real downstream consequences, and we need someone who catches that in review, not in production.
• Someone genuinely open to experimenting: we build with AI-assisted tooling (Claude Code is our primary build tool) and iterate fast, but every change ships with tests and goes through review against a written spec. We want someone who's energized by that combination of fast iteration and rigor, not one at the expense of the other.
• Good written communication. We're async-first and remote, and a lot of technical judgement gets exercised in writing.
• Comfortable working independently and taking a system from prototype through to monitored production.
