• Experience scaling email traffic several times while maintaining deliverability.

  • message delivery inconsistencies.

     

Channel Operations

Monitor channel performance daily using:

• Smartico Data Studio

• optimizing communication costs.

Incident Management

• Respond quickly to incidents such as:
  • delivery failures;
  • blocked sender IDs;
  • provider outages;
  • OTP attacks and SMS pumping.
• Escalate critical incidents to the CRM Lead.
• Prepare post-mortem reports and preventive action plans.
• Keep Product, CRM and CVM teams informed about major channel issues.

Cross-functional Collaboration

• Consult Product and CRM teams on communication channels and webhook configuration.
• Support IVR routing and communication flows.
• Prepare regular reports on channel performance, costs and improvements.

What We're Looking For

• Proven experience working with SMS aggregators, WhatsApp Business Providers (BSP), or similar communication providers at scale.
• Experience managing multiple vendors and negotiating pricing.
• Hands-on experience with:

Then we are waiting for you! 🤝

We are building an AI-driven VR platform for 
surgical planning that turns patient CT/MR 
scans into interactive, life-size 3-D anatomical 
models. We are looking for a Middle+ QA 
Engineer to own the quality of the product our 
clinicians actually run — on their own PCs, with 
their own GPUs, headsets and drivers.
Read this before you apply
This is not game QA. The product is built in 
Unity, but it is an application, not a game: no 
gameplay, no level design, no game mechanics. 
Unity experience matters because it lets you 
read the 3-D scene and the logs — but the 
hardest bugs in this product live outside the 
scene:
OS versions and builds, user permissions, 
admin vs. standard accounts
GPU vendors, models and driver versions — a
driver update can change what the surgeon 
sees
Headset runtimes and device detection
Installation, update, repair, uninstall — and 
what is left behind afterwards
Where files are written, what the app logs, 
what it does when the machine is not ideal
If you enjoy hunting down "it only happens on 
that laptop" problems and proving whether it is 
our bug or the machine's, you will do well here.
Because the software supports real clinical 
decisions, precision is not optional. Careful, 
methodical testing directly affects patient 
safety.
What We're Looking For
Desktop application testing (the core of this 
role)
3+ years of hands-on QA / software testing 
experience.
Solid experience testing desktop 
applications that users install on their own 
machines: installation, unattended install, 
update, repair and uninstall; clean-machine 
vs. upgrade scenarios; the app's footprint on 
the system (binaries, configs, user data, 
system settings, services); leftovers after 
uninstall; permissions and privilege levels.
Comfort with hardware and environment 
variability: different GPUs (integrated vs. 
discrete), driver versions, multi-monitor and 
DPI scaling, CPU/RAM limits. You can isolate 
an environment-specific issue, describe the 
environment precisely, and tell "our defect" 
from "this machine's configuration".
Ability to work with application logs, crash 
dumps and OS-level system logs to turn "it 
crashed" into a reproducible ticket.
Unity and 3-D
Hands-on experience testing Unity-based 3-
D applications (non-game applications are 
perfectly fine — arguably better).
Basic 3-D math and the ability to reason with
it: local vs. world coordinates, transforms 
(position / rotation / scale), units and scale, 
vectors, camera and projection, clipping 
planes, visibility. Enough to explain why an 
object is offset, mirrored, at the wrong scale, 
or not rendering — not just that it looks 
wrong.
Understanding of rendering and performance
basics: frame rate, smoothness, stability, and 
what degrades them.
Medical knowledge — the entry bar is low
To start, it is enough that you can look at a 3-
D reconstruction and tell an artery from the 
aorta. You are not expected to arrive as a 
radiologist.
What we do expect: real willingness to learn 
anatomy and imaging basics. You will be 
supported by developers and medical 
advisors, and you will grow into validating 
patient-specific models properly.
General QA
Experience testing web applications.
Strong QA fundamentals: test design, 
documentation, bug life cycle, types of 
testing.
Experience with bug-tracking and test-
management tools (Jira, TestRail or similar).
Basic API testing skills.
Good written and spoken English.
Exceptional attention to detail — small visual 
or data discrepancies can have real clinical 
consequences.
Fast, self-driven learner. VR, 3-D imaging and
medical concepts may all be new territory.
What You'll Do
Test the full desktop lifecycle: installer, 
updater, repair, uninstall — across OS 
versions and machine configurations, on 
clean systems and on upgrades; verify file 
locations, permissions and what remains 
after removal.
Test the Unity application across PC 
configurations and VR headsets: startup, 
device and driver detection, GPU/driver-
specific behaviour, performance, stability, 
and crash triage using logs and dumps.
Verify 3-D behaviour and spatial accuracy: 
transforms, scale, measurements at 
millimetre precision, clipping, layer visibility, 
annotations, camera behaviour and object 
interaction.
Validate patient-specific 3-D 
reconstructions against the source CT/MR 
studies: expected structures present, 
segmentation quality, spatial relationships, 
obvious reconstruction or visualization 
artifacts.
Test the web application(s): functional, 
regression, cross-browser, UI/UX.
Design and maintain test cases, checklists 
and test documentation.
Reproduce, document and verify defects — 
with exact environment details attached.
Nice to Have
Experience with VR headsets and their 
runtimes (SteamVR / OpenXR / Quest Link) 
and troubleshooting headset and tracking 
issues.
Graphics/driver-level debugging, GPU 
profiling, frame-timing analysis.
OS-level troubleshooting tooling: system and 
event logs, process/file monitors, dump 
analysis.
Experience testing non-game Unity software: 
CAD, simulation, scientific or medical 
visualization.
Background in medicine, anatomy, 
biomedical engineering, radiology or 
healthcare.
Familiarity with medical imaging concepts 
and formats (DICOM, PACS, CT/MR).
Experience validating segmentation results, 
3-D reconstruction quality or measurement 
accuracy.
Test automation or performance testing 
experience.

Amplifier AI is building a surgical planning 
platform powered by our own imaging, 
segmentation and 3-D measurement engine. 
We are a small team of engineers, radiologists 
and data scientists from Ukraine and across 
Europe. You would join the team developing the 
internal Python engine behind 3-D 
reconstruction and measurement for CT-based 
workflows.

Read this before you apply

We hire for reasoning about 3-D space, not 
for a title. The code itself is ordinary clean 
Python — the hard part is everything the 
geometry touches:
Voxel space vs. physical space, and every 
transform between them
Origin, spacing and direction — consistent 
across scanners, series and vendors
Real hospital data: incomplete series, odd 
orientations, inconsistent metadata
Geometric edge cases — surfaces that self-
intersect, clips that miss, distances that are 
"almost" right
Reproducibility: the same input must give the 
same number, today and in six months
If you can explain why a model is offset, 
mirrored or at the wrong scale — not just that it 
looks wrong — you will do well here.
Because the output feeds real surgical planning,
correctness is not negotiable. A wrong 
millimetre is a clinical problem, not a bug report.
This role is probably not for you if you want 
fully predefined tickets, a fixed roadmap, or to 
implement tasks without understanding the 
domain. Hospitals and real clinical data change 
priorities; we adjust as a team.

What We're Looking For

Python engineering (the core of this role)
- Clean, modular, strictly typed Python. We run 
mypy --strict, ruff, pytest, pre-
commit — and deep, technical code reviews.

- Confident with NumPy / SciPy and array-
heavy numerical code.

- Ability to own a feature end-to-end: from 
understanding the clinical problem to 
validating the result on real data.

3-D medical imaging fundamentals
-Understanding of origin, spacing and 
direction, and the difference between voxel 
and physical coordinates.

-Reading DICOM series correctly, validating 
RAS orientation, resampling without silently 
corrupting geometry.

-Comfort debugging complex geometric 
problems: distance, intersection, clipping, 
surface generation from labels.

Toolchain
-SimpleITK, VTK or PyTorch experience is a 
strong plus. If you haven't used them, you 
must be genuinely comfortable diving deep 
and learning independently — we mentor, but 
initiative is expected.
-Docker, Git, GitHub Actions, structured 
logging.

Ways of working
-Clear technical communication — you can 
explain your reasoning and defend a design.
-Ownership over micromanagement. Good 
written and spoken English.

What You'll Do
- DICOM & SimpleITK: read series correctly, 
validate RAS origins and directions, resample 
safely, maintain voxel ↔ physical transforms.
- VTK & geometry: generate surfaces from 
labels; implement distance, intersection and 
clipping algorithms; export reliable STL 
markers and geometry artifacts.
- Measurement & QA logic: build robust 
procedural tools for radiologists and handle 
the edge cases real hospital data produces.
- Pipeline reliability: performance tuning, 
structured logging, and making sure 
pipelines survive messy multi-scanner 
datasets.

Example challenges
- Build a robust distance-measurement tool 
between anatomical segmentations, with 
exportable nearest-point markers.
- Extract centerlines and anatomical landmarks
from noisy CT scans.
- Enforce consistent spacing / origin / direction 
across multi-scanner datasets.

If these sound exciting rather than 
overwhelming, you'll likely enjoy this role.

Nice to Have
- VTK surface / volume rendering experience.
- ML segmentation metrics and tooling (Dice, 
Hausdorff, nnU-Net, PyTorch).
- GPU acceleration and large-volume 
performance work.
- Background in radiology, biomedical 
engineering or clinical imaging.
