Jobs

Who are you? 

• You have strong skillset in full-stack development (core focus on backend and cloud infrastructure at scale) with the ability to identify problems and opportunities across the stack—and the initiative to solve them end-to-end

• 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 managing 1-2 person teams

• You are highly proficient in Python and modern backend frameworks (ideally FastAPI), with solid experience designing RESTful/GraphQL APIs, data models, and background jobs

• You have vast experience working with and shipping React/React Native, HTML/CSS/JavaScript/TypeScript projects

• You are experienced with cloud infrastructure setup and scaling (DigitalOcean/AWS/Azure/GCP), including VPCs, IaC (Terraform), containerization (Docker), orchestration (Kubernetes or managed alternatives), CI/CD (GitHub Actions), and observability (logs/metrics/traces)

• You are comfortable with datastores (e.g., PostgreSQL, MongoDB, time-series), caching (Redis), and message/IoT protocols (e.g., MQTT, webhooks, queues)

• 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 hold a degree in Computer Science, Computer Engineering, Electronics, and/or Data Science (or equivalent practical experience)

• 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, software, and SaaS/DaaS analytics (familiarity is a plus; your focus remains backend & cloud)

• 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)

• You are **London-based** and happy to commute **3+ days/week** to our Victoria-based co-working space

Desirable

• Have deployed and shipped code using FastAPI

• Familiar with containerised applications and SRE/CI/CD tools (Docker, Kubernetes/managed orchestration, Terraform, GitHub Actions)

• Strong database design ability and performance tuning (PostgreSQL, MongoDB, time-series)

• Observability: OpenSearch/ELK, Prometheus, Grafana, alerting and on-call readiness

• Node.js exposure for services, CLIs, or integrations

• 3rd-party API integrations and webhooks at scale

• IoT networking experience (MQTT, CoAP) and binary payload handling (e.g., Protocol Buffers)

• Experience with mobile (React Native, Expo) or frontend (React/TypeScript) is a plus

• Automated testing at multiple layers (unit, contract, integration, end-to-end) and tools like PyTest, Cypress (for UI)

• DevOps/Cybersecurity exposure (threat modeling, secrets, RBAC, audit trails)

• Low-level systems familiarity (embedded/firmware/PCB/C/Micropython) is a bonus

• Experience in tech-for-good and start-up/scale-up environments

What the job involves

• Design and build reliable backend services and APIs that ingest, validate, and process IoT telemetry at scale (including parsing and modeling device data, e.g., Protocol Buffers → Pydantic)

• Manage cloud infrastructure: set up and evolve secure, observable, cost-aware environments (VPCs, firewalls, SSL/TLS, IAM/RBAC), implement IaC (Terraform), and streamline CI/CD for fast, safe deployments

• Scale our platform as we expand across the UK, US, Canada and Germany—capacity planning, horizontal scaling, data partitioning, and resilience (HA, backups, disaster recovery)

• 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)

• Develop data models, visualisations, and analytics for flood warnings and predictive alerts—turning raw sensor data into actionable insights for clients

• 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

Application process

• Application submission via Welcome to the Jungle before 11:59 on Wed 3rd September

• Respond to initial screening questions sent via Welcome to the Jungle by 11:59 on Fri 5th September

• Technical screening (remote) with Full-Stack Engineer (30 mins) week of 8th September

• Final interviews (in person) with CTO/HR/CEO (full-stack tech assessment 60 mins, cultural fit 2x45 mins) w/c 15th September
