Principle duties and essential functions

• Perform precision sub‑assembly work: component prep, fiber attach, connectorization, and mechanical fixtures.
• Operate bonding/attachment equipment (e.g., epoxy dispense, UV/thermal cure) .
• Assemble and rework test fixtures, jigs, and custom adapters (basic machining/3D printing an advantage).
• Test station setup & maintenance
• Build and maintain RF and opto‑electronic test stations (RF cabling, terminations, attenuators, bias‑tees, probes, fiber routing, alignment stages).
• Calibrate and verify station performance (S‑parameter checks, optical power sanity checks, instrument self‑tests).
• Create and update station setup records, wiring diagrams, and calibration logs.
• Device testing & characterization
• Run standardized test plans for RFIC/PIC devices (DC I‑V, RF S‑parameters, eye diagrams, BER, EVM, noise, optical insertion loss, return loss).
• Use oscilloscopes, VNAs, spectrum analyzers, AWGs, SMUs, optical power meters, laser sources, TIAs, and photonic probes.
• Capture clean datasets, annotate conditions, and flag anomalies; perform first‑line troubleshooting of setups.
• Reliability & environmental screening
• Support qualification and stress testing (e.g., HTOL, temperature/humidity cycling, thermal shock, vibration, mechanical shock, damp heat).
• Execute test sequences safely; conduct interim read‑outs and maintain traceable logs.
• Process discipline & lab operations
• Follow ESD, clean handling, and safety protocols; maintain 5S standards across benches and storage.
• Prepare checklists, and batch records; ensure materials and consumables are stocked.
• Collaborate with engineers to improve build/test workflows; contribute to work instructions and other documents.

Knowledge, skills and experience required

Must-have

• Vocational training or associate degree in electronics, mechatronics, photonics, precision engineering, or related field; or equivalent hands‑on experience.
• 2+ years in an R&D or NPI lab supporting electronics or photonics (prototype builds and test).
• Strong bench skills: fine assembly, soldering (SMT/THT), optical fiber handling/alignment, torqueing RF connectors, cable management.
• Proficiency with core instruments: DMM/SMU, oscilloscope, VNA, spectrum analyzer, AWG, power supplies, optical meters/sources.
• Ability to read basic schematics, wiring diagrams, datasheets, and mechanical drawings.
• Experience with epoxy dispense and cure profiles.
• Familiarity with PIC testing (fiber alignment in V‑grooves, lens/lid fixtures, insertion/return loss, polarization handling).
• RF fixture/probe station experience (coax/precision adapters, microprobes, de‑embedding).
• Reliability testing exposure (HTOL, damp heat, thermal cycling; Telcordia/GR‑468 context is a plus).
• Basic CAD for fixtures (e.g., simple parts in SolidWorks/Fusion 360) or 3D printing.
• Scripting for data capture (Python, SCPI), or experience with LabVIEW.
• German language skills for local suppliers, HSE, and facilities coordination.
• Attention to detail: Clean builds, correct torque/adhesives, accurate measurements.
• Problem solving: Methodical troubleshooting of setups and measurement artifacts.
• Collaboration: Clear communication with RF/PIC design, test, and manufacturing engineering.
• Organization: 5S mindset, careful labeling, parts/consumables management.
• Safety & compliance: ESD, laser safety, RF exposure awareness, chemical handling.
• Possibility to work in an international, multicultural environment
• Strong team-oriented and friendly work culture
• Flexible working hours model
• Internal training program
• Fitness-, travel cost- and kindergarten allowance as well as drinks and fruits for free
• Employee discounts e. g. for events and branded products
