Company mission
To amplify the impact of healthcare professionals.
Role
Who you are
- Are you looking to impact and be part of something special, such as shaping the future of healthcare?
- Do you love solving complex problems and want your work to make a difference?
- We welcome applications from people of all backgrounds and all walks of life, including any typically underrepresented groups in the technology industry
What the job involves
- At Semble, we are on a mission to enable health professionals to amplify their impact
- We improve the way healthcare is delivered to millions of people by providing doctors and their teams with powerful, innovative, intuitive, and secure software
- Our cloud-based clinical system is already used by thousands of clinicians, making their lives easier and saving them money, while structuring their health data to help research
- We are a passionate and driven team, proud to unite under strong cultural drivers:
- Impact - We do work that matters
- Collaboration – We are in it together
- Human touch – We care deeply
- We are also quick to embrace new technologies: we have rapidly adopted AI internally, and we are always looking to work with people who are excited to augment their work with AI
- We are hiring a Head of Platform / SRE / Infrastructure / DevOps to define and execute our multi‑year platform strategy, ensuring reliability, scalability, security, and developer velocity for Semble’s cloud products
- You will own the vision and roadmap for our platform foundations (cloud, Kubernetes, CI/CD, observability, configuration management, cost, and compliance), lead a high‑impact team, and partner closely with Revenue, Data, Quality, Product and Engineering to enable rapid, safe delivery
- Reporting into our Vice President of Technology, you’ll shape this domain end‑to‑end — setting standards, building an empowered team, and delivering measurable outcomes across reliability (SLOs/SLA), security and compliance, deployment frequency, change failure rate, and time‑to‑restore
- This is a hands‑on leadership role: you will set strategy, coach and scale the team, and lead from the front on priority initiatives such as developer experience (e.g. ephemeral environment, re‑platforming CI/CD), zero‑downtime rollouts, and large‑scale platform improvements
- Set and communicate a clear vision, strategy, and action plan for Platform/SRE aligned to business goals; define multi‑year cloud architecture north star across infrastructure, and reliability
- Build, mentor, and manage a high‑performing team (SRE, Platform, DevOps, Infra), establishing strong stakeholder management and influence across Engineering, Data, Compliance, Security, and Product
- Define and enforce operational excellence standards (SLOs, incident management, on‑call, change management, RCAs) and nurture a culture of reliability and continuous improvement
- Establish and manage SLOs, error budgets, capacity planning, performance testing, and resilience engineering practices
- Lead initiatives for zero‑downtime deployments, progressive delivery, fast rollback strategies, and disaster recovery
- Drive observability (metrics, logs, traces), incident response, and post‑incident learning loops
- Re‑platform and standardise CI/CD (e.g., GitHub Actions, Argo CD) to accelerate safe delivery, reduce lead time, and improve change success rate
- Champion a developer‑first experience: build golden paths, templates, and paved‑road tooling for services, infra, and data workloads
- Implement configuration management at scale for repeatability and compliance (e.g., Ansible, Chef; Terraform/IaC)
- Lead large cloud migrations and platform transitions (e.g., to AWS and from AWS to private cloud or on‑prem data center) with clear cutover strategies and risk controls
- Own multi‑account/multi‑cluster strategy, networking, security baselines, identity, secrets, and data protection in partnership with Security and Compliance
- Optimise cloud footprint: set budgets/alerts, drive efficiency, and ensure predictable cost per workload
- Translate business objectives into a sequenced platform roadmap with clear outcomes and KPIs (DORA, SLOs, cost per tenant/workload); gain alignment with Product, Engineering, Security, and Data
- Establish crisp engagement models with Product/Engineering, with Security/Compliance, with Data/Analytics
- Create working agreements and SLAs with product teams for on‑call, incident command, and escalation; activate post‑incident reviews focused on systemic fixes
- Communicate trade‑offs with clarity to technical and non‑technical stakeholders; influence decision‑making across domains and geographies (France and the UK)
Our take
In healthcare, overloaded systems riddled with room for error are in dire need of an overhaul. Semble (previously Heydoc) is one of the startups stepping in to try and fix the problem. Its integrated clinical system aims to help practices manage patient data and streamline their administration and operations.
Semble is not the only option in the market, but its focus on private hospitals and clinics may well work to its advantage, as many of its competitors primarily target the NHS. The company's cloud-based system aligns the company with the broader trend towards cloud-based operations, another good sign for its future growth.
A well-funded business, Semble has been able to remain at the forefront of innovation through adding automation and most recently, AI to its system. A considerable influx of investment in 2024 will help to consolidate its market position in the UK as well as support the expansion of its newer presence in France.
