Job description

About SAVA

All the health information we need is within us. Just below the skin. SAVA is redefining the way people interact with their health by developing the most advanced biosensing technology science has to offer, capable of accessing bodily information in a painless, real-time and affordable way.

The Role

We’re looking for a passionate Process Development Engineer to turn manual workflows into robust, scalable manufacturing processes. This onsite role sits at the intersection of hands‑on experimentation and data‑driven decision‑making, working from early prototypes through to production‑ready systems. It offers the opportunity to work at the cutting edge of product realisation in a fast‑paced, multidisciplinary environment.

You’ll collaborate across internal teams such as Sensor Development, Automated Equipment, Mechanical Engineering, and Data Engineering, as well as external vendors and suppliers to transform uncharacterised manual or semi‑automated processes into well‑defined, optimised, and monitored manufacturing workflows.

You will act as the subject matter expert for 2–4 manufacturing processes, defining process windows and recipes, characterising limits, and optimiser for quality, yield, and throughput—enabling seamless integration with evolving product designs.

This is a role for engineers who thrive in ambiguity, define acceptance criteria (or adapt existing ones), push processes from nominal functionality to tightly controlled, validated performance, communicate clearly, and take full ownership of processes and cross‑functional alignment — building processes and performance metrics that work not just in theory, but at scale.

What You’ll Do

Process Development

• Develop scalable, repeatable processes from early manual or semi‑automated stages
• Define process parameters, windows, and manufacturing recipes
• Characterise process limits and optimise for yield, throughput, and stability

Process Control & Metrics

• Establish and monitor metrics for quality, throughput, and yield
• Implement systems to track and visualise process health
• Use data to drive decision‑making, troubleshooting, and continuous improvement

Cross‑Functional Collaboration & Ownership

• Act as the project manager for your processes, aligning priorities and timelines
• Communicate risks, wins, and progress clearly to stakeholders
• Liaise with suppliers and internal teams to enable successful process execution
• Collaborate closely with Sensor Development, Automated Equipment, Mechanical Engineering, and Data Engineering teams

Verification & Validation

• Develop test protocols and qualification strategies (IQ/OQ/PQ)
• Ensure processes meet functional and regulatory requirements
• Support operator training, auditing, and vendor management

What We’re Looking For

• Degree in Engineering (Manufacturing, Mechanical, Industrial, or Biomedical)
• 2–5 years of experience in process development or manufacturing engineering, preferably in a regulated industry (medical devices, aerospace, automotive, etc.)
• Proven ability to develop, characterise, and optimise manual or semi‑automated manufacturing processes
• Strong background in experimental design, statistical analysis, and root cause problem solving
• Hands‑on experience with setting process windows, recipes, and acceptance criteria
• Familiarity with process qualification (IQ/OQ/PQ) and test method validation
• Comfortable managing multiple projects simultaneously and working cross‑functionally with R&D, automation, data, and mechanical engineering teams
• Strong communication skills to clearly convey technical issues, risks, and results to stakeholders at all levels

Bonus Points For

• Experience with data‑driven process control, manufacturing dashboards, or metrics development
• Exposure to high‑volume or scale‑up manufacturing environments, specifically medical devices
• Proficiency in statistical tools (e.g., JMP, Minitab, or similar)
• Lean Six Sigma Black Belt or equivalent process improvement training

Why Sava?

This is a high‑ownership, high‑responsibility role in a company that’s building something complex, meaningful, and fast. The expectations are high, the learning curve is steep, and the work is often messy—but the impact is real.

We don’t have room for egos or passengers. What we do have is a team of thoughtful, driven, and mission‑aligned people who are committed to building something better—and doing it with urgency and integrity.
