Full-Stack Engineer - IoT Backend & Cloud Infrastructure

ManholeMetrics is looking for an experienced Full-Stack Engineer to join their team as they scale their sewer and stormwater collection system monitoring solution across the US, Canada and UK.

Who you are

• You have strong skillset in full-stack development with the ability to identify problems and opportunities across the stack—and the initiative to solve them end-to-end
• You are experienced with cloud infrastructure setup and scaling (ideally AWS), including VPCs, IaC (CDK), containerisation (Docker), orchestration (Kubernetes or managed alternatives), CI/CD (GitHub Actions), and observability (logs/metrics/traces)
• You are very comfortable with relational database usage, schema design and optimisation.
• You are highly proficient in Python and modern backend frameworks with solid experience designing RESTful APIs, GraphQL schemas, data models.
• You enjoy creating reproducible, repeatable make based workflows that increase Developer Experience
• You have 3–5 years of industry experience with a proven track record of shipping reliable services to production and operating them at scale, following industry best practices and a strong belief in maintaining code quality.
• You have experience working with and shipping React/TypeScript projects
• You care deeply about security, reliability, and cost efficiency—familiar with least-privilege access, secrets management, SSL/TLS, and compliance-minded logging
• You have a portfolio you’re proud of (e.g. deployed services, internal platforms, open-source repos)
• You’re excited to learn and apply new languages, frameworks, and tools to create real-world solutions
• You’re a pragmatic problem-solver who employs design thinking, values sound engineering principles, and pays close attention to detail
• You enjoy multi-faceted exposure to work-streams in IoT, sensor technology, networking, embedded systems, app development, firmware. You can follow data from a IOT device modem broadcast through to a cloud hosted database Searching for Development & Programming roles that provide visa sponsorship? Connect with international employers through Development & Programming Jobs with Visa Sponsorship opportunities actively seeking talented professionals.
• You communicate clearly—translating client needs into robust engineering solutions and explaining complex concepts to non-technical stakeholders
• You thrive in a small, diverse team, excel under pressure, and proactively step into new challenges—start-up dynamism suits you
• You’re an ecowarrior at heart—motivated by building technology that combats climate change and delivers measurable societal impact
• You have the right to work in the UK or a visa with at least 6 months remaining (we can sponsor a Skilled Worker visa post-probation)

Desirable

• IoT networking experience (HTTPS/MQTT) and binary payload handling (e.g. Protocol Buffers)
• Automated testing at multiple layers (unit, contract, integration, end-to-end) and tools like PyTest, Cypress (for UI)
• Experience with mobile (React Native, Expo) or frontend (React/TypeScript)
• DevOps/Cybersecurity exposure (threat modelling, secrets, RBAC, audit trails)
• Low-level systems familiarity (embedded/firmware/C)
• Experience in tech-for-good and start-up/scale-up environments
• You hold a degree in Computer Science, Software Engineering (or equivalent practical experience) Explore our comprehensive directory of visa sponsorship jobs from employers worldwide who are ready to sponsor talented international professionals.

What the job involves

• Design and build reliable backend services and APIs that ingest, validate, and process IoT telemetry at scale (including parsing and modelling device data, e.g., Protocol Buffers → Pydantic -> Postgres)
• Being a core member of our migration team, migrating from a legacy MongoDB environment to a modern AWS hosted GraphQL and Postgres platform.
• Manage cloud infrastructure: set up and evolve secure, observable, cost-aware environments (VPCs, firewalls, SSL/TLS, IAM/RBAC), implement IaC (CDK), and streamline CI/CD for fast, safe deployments
• Instrument the stack end-to-end (logs, metrics, traces) and improve reliability with SLOs, runbooks, and alerting; drive incident response and post-mortems
• Collaborate across the stack with firmware, app, and frontend engineers to plan, produce, test, and deploy new capabilities (device ↔ backend ↔ dashboard). Automate and optimise workflows: testing, data pipelines, release processes, and developer tooling (including Gen AI) to boost team velocity and quality
• Balance speed and quality, focusing on tangible outcomes while maintaining high engineering standards and documentation
• Work shoulder-to-shoulder with the CEO and engineering team on system-level design and end-to-end architecture as we scale rapidly and robustly

Compensation

• £60-80k per annum (experience dependent)
