Top Tech Jobs & Startup Jobs in London

Design, build, deploy, and optimize production AI systems, including LLM integrations, RAG pipelines, embeddings, vector search, predictive models, and inference systems. Collaborate with product and engineering teams to translate business needs into scalable solutions for recommendations, risk scoring, forecasting, and workflow automation. Own data pipelines, monitoring, evaluation, security, privacy, documentation, and continuous model improvement across cloud environments.

Lead full-stack development and co-manage a lean engineering team to build SunCore's web and mobile infrastructure. Implement CI/CD, migrate hosting to DigitalOcean with Cloudflare, migrate CRM to HubSpot via Zapier, integrate multiple APIs and third-party services, and deliver a secure Flutter mobile app and dashboard with SOC2-level security, 2FA/biometric login, and wallet integrations.

Secure and scale cloud infrastructure by implementing CI/CD, hardening DigitalOcean and other cloud environments, managing certificates and DNS, integrating IAM/SSO and KYC providers, applying DevSecOps practices, automating infrastructure as code, participating in incident response, and collaborating with engineering teams to optimize deployments and reduce downtime.

Blend DevOps and security engineering to secure cloud infrastructure, CI/CD pipelines, web and mobile apps, and third-party integrations. Conduct penetration testing, threat modeling, automate security checks, manage certificates/DNS/Cloudflare, enforce access control and secrets management, support KYC-compliant onboarding, and lead incident response and SOC2 readiness.

Test and validate Flutter-based Android and iOS apps across devices and OS versions. Perform functional, exploratory, regression, integration, lifecycle, connectivity, API, and release validation. Maintain device/OS coverage, document reproducible defects, develop selected mobile automation, integrate tests into CI/CD, and coordinate with developers, QA, UI/UX, and DevOps to ensure mobile release quality.

Build and maintain high-performance cross-platform mobile apps with Flutter and Dart. Integrate RESTful APIs and real-time data, optimize performance and accessibility across iOS and Android, participate in sprint planning and code reviews, maintain CI/CD pipelines, and help define mobile architecture and UI/UX implementation.

Hands-on role to assess, implement, test, and document backup, restore, failover, and recovery capabilities. Inventory critical systems, design and automate backup and restoration, run recovery exercises, produce runbooks, validate recoverability, measure RTO/RPO, and train system owners. Collaborate with Security, SRE, DevOps, QA, and application teams to harden shared recovery capabilities and transfer operational ownership.

Lead security assessments and controls across cloud-hosted applications, APIs, mobile (Flutter), CI/CD, and infrastructure. Implement and harden shared security tooling (dependency/secret/static/container scanning), review IAM and privileged access, support incident readiness and monitoring, evaluate SRE/recovery changes for security impact, and coordinate remediation with system owners. Establish security policies, automation, and review triggers to integrate practical controls into engineering workflows.
