Core Responsibilities

Primary Functions

Execute and document repeatable unit-level experiments, assembly tasks, or component tests following established SOPs, ensuring all steps and results are captured in the team's laboratory notebook, test logs or Jira tickets.
Design and run unit tests (manual and automated) for software modules using frameworks such as pytest or JUnit; write clear test cases, report defects in tracking systems, and verify fixes as part of continuous integration workflows.
Assist with instrument setup, calibration and routine maintenance of bench equipment, sensors or test rigs; diagnose basic instrumentation issues and escalate complex faults to senior technicians.
Collect high-quality time-series, image or tabular data from experiments and tests; validate and preprocess datasets for downstream analysis or model training while maintaining data provenance and metadata.
Create reproducible scripts (Python, MATLAB or R) to automate data ingestion, cleaning and common analysis tasks; produce summary tables and visualizations for weekly reports and design reviews.
Support the unit's build and assembly activities including component procurement checks, bill of materials verification, and hands-on assembly under supervision, improving throughput and reducing rework.
Execute root cause analysis on failed unit tests or experiment runs, capturing failure modes, replicating defects, and proposing corrective actions to reduce recurrence.
Maintain and update technical documentation including standard operating procedures (SOPs), test plans, assembly guides, and version-controlled design notes to ensure knowledge continuity.
Participate actively in daily standups, sprint planning and demo sessions; communicate blockers, estimate small tasks, and deliver incremental outcomes aligned with the sprint goals.
Run regression test suites on devices or services after firmware, hardware, or code changes; report flaky tests, contribute to test stabilization, and help reduce false positives.
Prepare clear, data-driven summaries and presentations for internal stakeholders that highlight key findings, experimental methodology, and recommended next steps.
Assist in sample preparation, labeling, chain-of-custody and storage for experiments governed by safety and compliance protocols; ensure accurate labeling and traceability.
Support the generation and maintenance of unit-level dashboards (Power BI, Tableau or Grafana) for tracking KPIs like pass/fail rates, throughput, defect trends and test coverage.
Carry out inventory management tasks: track consumables, reorder parts using procurement systems, and reorganize storerooms to reduce retrieval time and improve efficiency.
Implement small software fixes or scripting improvements in collaboration with senior engineers (Git workflow), create pull requests with clear descriptions, and respond to code review feedback.
Perform manual exploratory testing on new features or prototypes, document user flows and edge cases, and collaborate with designers and engineers to improve usability and reliability.
Adhere to workplace safety, EHS and regulatory requirements (PPE, safe handling of chemicals, documentation), participate in safety training, and report incidents promptly.
Conduct literature reviews and competitor analysis to inform experimental designs and identify best practices for unit-level performance improvement.
Facilitate cross-functional handoffs by preparing itineraries, test checklists, and acceptance criteria when moving units between development, QA and production environments.
Support the rollout of small-scale pilot deployments or A/B tests at the unit level; assist with instrumentation, monitoring and capture of success metrics.
Help develop and maintain test fixtures, jigs and custom tooling to improve repeatability of experiments and unit tests; propose iterative design improvements.
Assist senior staff with compliance documentation for internal audits, recording calibration certificates and evidence of completed corrective actions.
Perform basic statistical analysis (t-tests, regressions, confidence intervals) on experimental results to quantify impact and significance for decision-making.
Shadow and learn from senior engineers or scientists on complex troubleshooting, system debugging and cross-domain integrations to accelerate on-the-job learning.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist in onboarding new interns or temporary staff; prepare orientation materials and unit tours.
Provide administrative support for unit test schedules, lab bookings and stakeholder coordination.
Help implement small continuous improvement projects to reduce cycle time or defects at the unit level.
