We are looking for a talented Mechanical Design Engineer to join our dexterous hands development team. You will work alongside senior engineers who lead this field and bring extensive experience in miniature mechanisms.
This is a highly hands-on position in a fast-moving, multidisciplinary environment. You will take mechanisms from early concepts through detailed design, prototyping, testing, iteration, and preparation for production.
Responsibilities:
Design compact, high-performance mechanisms for dexterous robotic hands, fingers, and wrists.
Develop joints, transmissions, actuation systems, tendon or cable-driven mechanisms, and sensor-integrated components.
Perform kinematic, force, tolerance, and structural analyses.
Create detailed 3D CAD models, assemblies, production drawings, and bills of materials.
Build and assemble prototypes and conduct hands-on mechanical testing.
Design test fixtures and define practical validation procedures.
Investigate failures, identify root causes, and rapidly implement design improvements.
Select materials, bearings, fasteners, springs, cables, actuators, sensors, and manufacturing processes.
Work closely with controls, electronics, software, industrial design, and manufacturing engineers.
Collaborate with suppliers and support the transition from prototypes to repeatable production.

Required Composite Structures Engineer
Why this role exists
The airframe is not just a load path - it is part of the acoustic system. Every panel that vibrates radiates, every joint that transmits structure-borne energy undoes work the rest of the vehicle did to stay quiet. You will design and substantiate the composite structure of a novel lift and propulsion architecture where laminate stiffness, ply-level damping, and transmission-path isolation are traded as deliberately as mass and strength - because our roughly fourfold acoustic advantage survives only if the structure carries it.
What you'll own:
Design composite primary and secondary structure - laminate definitions, ply schedules, core selections, bonded and bolted joints - from concept layout through released engineering definition.
Build, run, and own detailed FEA models for static strength, buckling, and structural dynamics, and keep them correlated against coupon, element, and full-scale test evidence.
Drive vibro-acoustic behavior of the airframe: characterize panel modal density, radiation efficiency, and structure-borne transmission paths, and turn stiffness and damping into deliberate acoustic design levers.
Define and execute structural test campaigns - building-block coupon and element tests, modal surveys and ground vibration tests - including instrumentation plans, test readiness reviews, and post-test model correlation.
Develop material allowables and laminate design values with materials and process engineers, and document the basis for every margin you claim.
Write structural substantiation reports with traceable loads, methods, and margins of safety that will stand up to a certification authority, not just an internal review.
Trade mass against transmission loss and damping treatments directly with the Acoustics team, and defend the structural side of those trades at vehicle-level design reviews.
Support the build: assess layup and tooling feasibility, review first articles, and disposition manufacturing discrepancies on flight hardware.

Required Systems Integration Engineer
Why this role exists
On most aircraft programs, systems engineering keeps the weight, power, and safety budgets honest. There is a fourth budget - noise - and it is the one the company lives or dies by, flowed down through every interface, mount, harness, and duty cycle on the vehicle. This role exists because a roughly 4 acoustic advantage is an architecture claim until someone turns it into a closed set of vehicle-level requirements, traces every one to a subsystem owner, and walks the verification evidence onto the flight line.
What you'll own:
Own requirements flow-down from vehicle-level acoustic, performance, and safety targets to subsystem specifications under an ARP4754A-aligned development process.
Author and control interface definitions across structures, propulsion, avionics, and software - including the vibration, isolation, and acoustic constraints most ICDs never carry.
Build and maintain the vehicle requirements and verification database with full bidirectional traceability from stakeholder need to test evidence, and defend it in audits.
Plan and run integration campaigns on the systems bench and iron bird: power-on sequencing, interface checkout, fault injection, and end-to-end functional verification before anything flies.
Lead ground and flight test campaigns as the vehicle-level V&V owner - define test objectives, success criteria, and instrumentation requirements, then reconcile measured results against requirements line by line.
Chair cross-subsystem integration reviews and arbitrate trades where a decibel saved in one subsystem costs mass, power, or schedule in another.
Conduct safety assessment work - FHA, PSSA, FMEA, and fault trees per ARP4761 - jointly with subsystem leads, and track every derived requirement to closure.
Drive gated design reviews from SRR through test readiness with hard closure metrics: verification status, open interface items, and integration risk burn-down.

Required Electric Propulsion Engineer
Why this role exists:
We exist to make urban flight quiet enough that cities say yes. In electric aircraft, once aerodynamic sources are suppressed, the drivetrain can become what remains: torque ripple, radial force harmonics, and inverter switching rise toward the dominant tones an observer on the ground hears. This role owns the electric propulsion system as an acoustic source - you will design motors and drives where electromagnetic noise is a first-order requirement, traded with the same rigor as power density, efficiency, and mass.
What you'll own:
Design and analyze motor electromagnetics with torque ripple, cogging torque, and radial force harmonics treated as hard requirements alongside efficiency and power density.
Develop inverter modulation and current-control strategies - including harmonic injection and active ripple compensation - that suppress electromagnetic excitation before it becomes radiated tone.
Build and validate multiphysics models chaining electromagnetic force prediction through structural transfer paths to radiated noise, correlated against dyno and vehicle data.
Plan and execute dyno test campaigns with synchronized electrical, vibration, and acoustic instrumentation, owning the data pipeline from raw capture to engineering verdict.
Integrate motors, inverters, and mounts into the vehicle's novel lift and propulsion architecture, working structure-borne transmission paths jointly with the Structures and Acoustics teams.
Characterize thermal behavior on the dyno and derive continuous and peak torque envelopes that hold across the full flight profile.
Define acceptance and qualification test procedures for propulsion units, including back-EMF, efficiency-map, vibration, and acoustic signature checks.
Lead propulsion design reviews and hardware failure investigations, driving root cause to closure with documented corrective actions.

Required Aerodynamics Engineer
Why this role exists:
Aerodynamics and acoustics are not separate disciplines - every flow decision is a noise decision. We are building an aircraft whose acoustic signature is roughly 4 lower than conventional eVTOLs, and that margin is won or lost in the details of unsteady flow around our novel lift and propulsion architecture. This role exists because we need an aerodynamicist who treats sound as a first-order design constraint, not a downstream check, and who can carry a configuration trade from CFD through the wind tunnel to flight data.
What you'll own:
Own aerodynamic design and analysis of vehicle-level configurations, trading lift-system efficiency directly against acoustic source strength across all phases of flight.
Build and run high-fidelity CFD campaigns - steady RANS for performance maps, unsteady and scale-resolving simulations where acoustic source prediction demands it - with documented mesh and turbulence-model sensitivity studies.
Couple aerodynamic predictions to acoustic propagation models, working with the Acoustics team to trace far-field noise back to specific unsteady flow mechanisms on the vehicle.
Plan and execute wind tunnel test campaigns end to end: model definition, instrumentation plans, test matrices, on-site execution, and post-test correlation against CFD predictions.
Develop and maintain the vehicle aerodynamic database - polars, control derivatives, and interactional effects - feeding flight dynamics, performance, and loads analyses.
Correlate predictions against flight test data, drive down model uncertainty, and publish updated aero models with quantified validation status.
Present design trades and analysis results at internal design reviews, defending recommendations with data when performance and noise pull in opposite directions.
Define aerodynamic requirements and acceptance criteria for vehicle hardware, and review geometry releases for compliance with the validated aero lines.

Required Acoustics Research Engineer
Why this role exists
Noise - not range, not cost - is what keeps aircraft out of cities. We exist because we believe an acoustic signature roughly four times lower than conventional eVTOLs changes what urban aviation is allowed to be, and this role sits at the exact center of that bet. You will own the methods that tell us, with numbers we can defend, how quiet the vehicle actually is - and where the next decibel comes from.
What you'll own:
Develop and validate source-noise prediction models for our novel lift and propulsion architecture, from first-principles aeroacoustics through empirically anchored corrections.
Design and execute acoustic measurement campaigns in anechoic facilities and at outdoor ranges, owning microphone array design, calibration chains, and data acquisition end to end.
Reduce rig and flight-test acoustic data into validated spectra, directivity maps, and component-level source rankings that directly drive vehicle design decisions.
Quantify community-noise exposure using EPNL, SEL, dBA, and tonality-corrected metrics, and translate the results into hard, testable requirements for design teams.
Build psychoacoustic models - loudness, sharpness, tonality, fluctuation strength - and run jury listening studies that connect physical metrics to human annoyance.
Run aeroacoustic simulations coupling CFD to acoustic analogy solvers (FW-H or equivalent), and reconcile predictions against measured data every design cycle.
Define and defend the vehicle noise budget at design reviews, allocating margins across subsystems and flagging acoustic risk before hardware is built.
Author measurement procedures, test reports, and model validation documents rigorous enough to anchor future certification arguments.
