JOB TYPE
Permanent The Role We are looking for a Technical Architect to take joint ownership of two critical dimensions: shaping the architecture of our platform and providing hands-on technical leadership to our engineering team. You will be a key decision-maker in how we build, scale, and evolve our systems - balancing technical excellence with practical delivery. You will work closely with engineering, AI/ML, and product teams, and you will have a direct impact on the technology roadmap of a fast-growing startup in a highly regulated and meaningful space. Responsibilities Systems Architecture Design and evolve the overall platform architecture - backend services, ML inference pipelines, and clinical integrations - ensuring scalability, security, and performance. Define and enforce architectural patterns, coding standards, and technology decisions with a long-term perspective. Evaluate and select technologies, frameworks, and tools, clearly articulating trade-offs to both technical and non-technical stakeholders. Ensure architecture decisions account for the regulatory requirements of the medical device space (MDR, FDA SaMD). Lead the technical design of integrations with hospital systems (PACS, HIS) using standards such as DICOM and
HL7/FHIR.
Own non-functional requirements: reliability, latency, data privacy (GDPR, HIPAA-aligned), and disaster recovery. Technical Leadership Be the technical reference for the engineering team: code reviews, mentoring, and establishing engineering best practices. Collaborate with the AI/ML team on the productionisation of inference models and the optimization of the end-to-end ML pipeline. Contribute to sprint planning and technical estimation, helping the team break down complexity into deliverable increments. Proactively identify and mitigate technical risks, communicating them clearly before they become blockers. Foster an engineering culture centred on quality, automation, observability, and continuous improvement. Requirements Must-haves 5-8 years of software engineering experience, with at least 2-3 years in architecture or senior technical leadership roles. Proven experience designing and operating cloud-native systems on AWS (compute, storage, networking, managed services, IAM). Strong background in Python for production environments - APIs, data processing pipelines, and ML model integration. Solid understanding of containerisation (Docker) and orchestration in production environments. Deep knowledge of distributed systems design principles: microservices, event-driven architecture, API design, and data consistency patterns. Experience building CI/CD pipelines and driving DevOps practices across an engineering team. Ability to document and communicate architecture decisions clearly, both in writing and in technical discussions. Comfortable operating in a startup environment: autonomous, pragmatic, and able to balance ideal solutions with real constraints. Nice-to-haves Experience deploying and optimising ML models in production - including ONNX Runtime or similar inference frameworks.
Familiarity with medical imaging standards:
DICOM, HL7, FHIR.
Background in regulated environments (MDR, FDA 21 CFR Part 11, ISO 13485, or similar).
Experience with MLOps practices:
model versioning, drift monitoring, and retraining pipelines. Knowledge of PHP/Laravel or experience working with and evolving an existing codebase built on it. Prior experience in healthtech, medtech, or other highly regulated industries. What We Offer Competitive salary aligned with your experience and the market. Hybrid model with real flexibility - we care about outcomes, not hours. Direct, visible impact: your work shapes tools that help clinicians make better diagnoses. Small, highly skilled team with strong technical autonomy. Annual budget for training, conferences, and certifications. Freedom to challenge the status quo and propose improvements to how we build things. A collaborative, mission-driven environment where engineering is taken seriously. CONTACT Tim Lucas Manager
