We are building a digital orthodontics platform with interactive browser-based 3D tools and backend mesh-processing services.

This is a hybrid role combining native computational geometry in C++, browser-based 3D development with Three.js and TypeScript, full-stack development with Angular and Node.js, and deployment of geometry-processing workloads to AWS.

You will be able to take a 3D feature through its complete lifecycle: implement the geometry algorithm, expose it through a backend service, build the browser interaction, and deploy the complete workflow to production.

Important: this is not a 3D visualization-only position. The role requires hands-on experience with mesh manipulation, computational geometry, 3D mathematics, and geometry-quality validation.

You Are

• A Software Engineer with commercial experience building 3D, CAD, mesh-processing, medical 3D, 3D-printing, scientific visualization, or similar systems.
• Strong in modern C++17 or later, including memory management, performance profiling, native libraries, and dependency management.
• Strong in JavaScript/TypeScript and experienced with browser-based 3D development using Three.js or raw WebGL.
• Experienced with computational geometry and direct manipulation of triangle meshes.
• Familiar with mesh topology, normals, boundaries, connected components, non-manifold geometry, coordinate systems, units, and numerical tolerances.
• Have implemented or integrated mesh operations such as repair, remeshing, simplification, smoothing, cutting, Boolean operations, offsets, distance queries, collision/contact detection, or registration.
• Have practical experience with at least one geometry-processing library or SDK such as VTK, CGAL, Open3D, libigl, MeshLib, OpenMesh, or similar.
• Comfortable with the mathematics behind 3D systems, including vectors, matrices, transformations, projections, quaternions, linear algebra, and spatial queries.
• Familiar with spatial data structures and acceleration techniques such as BVH, octrees, or k-d trees.
• Experienced with Three.js concepts including BufferGeometry, materials, cameras, raycasting, object transforms, interaction tools, and rendering-performance optimization.
• Have practical experience with Angular and reactive application architecture using RxJS or equivalent patterns.
• Have backend experience with Node.js and Express or a comparable framework.
• Comfortable integrating native C++ processing with web services through a CLI, native library, binding, API, or containerized worker.
• Experienced with CMake, Linux, Docker, Git workflows, pull requests, and code review.
• Able to write automated tests for geometry code using fixtures, invariants, tolerance checks, and regression datasets.

• Able to investigate problems across the entire system—from incorrect geometry output to API integration, browser interaction, or cloud execution.

   

Will Be a Plus

• Experience with multiple geometry-processing libraries or commercial 3D SDKs.
• Experience with AWS services such as S3, SQS, Step Functions, ECS/Fargate, AWS Batch, Lambda, ECR, CloudWatch, and IAM.
• Experience designing asynchronous and long-running processing workflows.
• Experience with Infrastructure as Code using Terraform, AWS CDK, or CloudFormation.
• Experience with C++ bindings such as pybind11 or nanobind.

• Experience with three-mesh-bvh, GLSL shaders, large-mesh rendering, or custom Three.js interaction tools.
• Experience evaluating third-party geometry SDKs, including benchmarks, licence restrictions, and headless deployment.
• Background in medtech, healthcare, dental CAD/CAM, scientific visualization, or 3D printing.

• Familiarity with AI-assisted development tools such as Cursor, Claude Code, or Codex.

   

What We Expect from You

• Own 3D features from geometry implementation through backend integration, browser tooling, and production deployment.
• Work directly with mesh data and geometry algorithms, not only with rendering and visual appearance.
• Define clear tolerances, invariants, validation rules, and quality checks for geometry operations.
• Identify cases where an operation cannot produce a reliable result and report them clearly.
• Make practical engineering decisions that help us deliver quickly without unnecessary overengineering.
• Proactively identify geometry-quality, rendering, performance, memory, and scalability issues.
• Maintain clear contracts between C++ processing, backend services, and browser-based 3D tools.
• Be comfortable working in an evolving product with changing priorities and early-stage ambiguity.
• Review, test, and validate AI-generated code before using it in production.

• Communicate effectively with domain experts, frontend engineers, backend engineers, and infrastructure engineers.

   

Responsibilities

• Build and improve native C++ mesh-processing tools and libraries.
• Implement and integrate computational geometry algorithms for processing and modifying complex 3D meshes.
• Build interactive browser-based 3D tools using Three.js and TypeScript.
• Implement Angular components, services, state management, and user workflows for 3D features.
• Develop Node.js/Express APIs that connect browser tools with native geometry-processing services.
• Define stable contracts for mesh formats, metadata, units, coordinate systems, transforms, inputs, outputs, and errors.
• Package C++ geometry operations as reliable headless Linux workers using Docker.
• Deploy geometry workers to appropriate AWS compute services and orchestrate them using Step Functions, queues, and object storage.
• Implement asynchronous job execution, progress reporting, retries, timeouts, failure handling, and structured error reporting.
• Optimize geometry-processing time, memory usage, output quality, browser rendering, and data transfer.
• Write unit, integration, end-to-end, and geometry-regression tests.
• Create representative mesh fixtures and tolerance-based quality checks.
• Investigate issues across C++, Node.js, Angular, Three.js, Docker, and AWS.
• Participate in technical design discussions, pull-request reviews, and engineering best practices.

• Use AI-assisted development tools responsibly to improve development speed and code quality.

   

What We Offer

• Work on an innovative product in the medical-tech and 3D geometry domain.
• High ownership and direct impact on product and technical decisions.
• The opportunity to work across computational geometry, browser 3D, backend systems, and cloud infrastructure.
• Flexible working hours within the European time zone.

About the Role

• We are hiring a Senior Full-Stack Engineer to become one of the strongest technical contributors on the team.
• The single most important thing we’re looking for is experience scaling a SaaS product. We want someone who has already seen what happens as a live platform grows: increasing complexity, technical debt, scaling bottlenecks, evolving data models, unreliable integrations, and engineering decisions that worked at one stage but became expensive at the next.

• This is a hands-on senior engineering role with strong technical leadership expectations. You will design and write production code, own substantial systems end to end, influence architectural decisions, challenge technical direction when needed, and raise the engineering level of the people around you.

   

Project

• FinTech SaaS platform built for the restaurant and hospitality industry. Our products handle tip pooling and payouts, payroll, reporting and compliance, labor and operational data, and integrations with the systems hospitality businesses already use. The platform is live, serves thousands of customers and moves millions of dollars.

   

Required Hard Skills

• Several years operating at Senior Engineer level on a SaaS product that grew significantly while you were there. You have seen a system become meaningfully bigger and understand the problems that tend to arrive next.
• Strong Python and Django / Django REST Framework experience, or deep experience in a closely comparable backend stack.
• Strong React and TypeScript experience, with the ability to work effectively across backend and frontend when required.
• Strong PostgreSQL and data modeling skills. You should be comfortable designing schemas that can evolve as the business grows into new products and safely changing them once they contain production data.
• Production experience with asynchronous and distributed workloads using Celery or comparable technologies.
• Strong understanding of API design and third-party integrations, including failure handling, retries, idempotency, data consistency, reconciliation, and situations where the system on the other side is unreliable or outside your control.
• Strong understanding of software architecture and the ability to make pragmatic architectural decisions inside a large existing codebase rather than only designing systems from scratch.
• Experience identifying and addressing performance, scalability, reliability, and maintainability problems before they become critical.
• Strong testing practices and experience safely evolving systems that must remain operational while they are being changed.
• Production experience with Docker, CI/CD, monitoring, error tracking, and observability. 
• Strong Linux knowledge. 
• Sound judgment about technical debt: knowing the difference between an acceptable shortcut and one that will create significant problems later, and being able to improve a system while it remains in production.
• Everyday experience with using AI agents for work (Claude Code or Codex). Familiar with configuring AI toolset, understanding pros and cons of modern AI.

Current Stack

• Django / DRF, PostgreSQL, Redis, Celery, Docker, Traefik, Datadog, Sentry, Mailgun, GitHub Workflows.
• Next.js, MUI, TanStack Query, React Hook Form, Zod, Vitest.

Nice to Have

• FinTech or financial systems experience, particularly payments, payouts, ledgers, reconciliation, payroll, banking, audit trails, or other systems where financial correctness matters.
• Experience with restaurant or hospitality technology, including POS, scheduling, workforce management, payroll, or similar systems.
• Experience with high-volume or business-critical third-party integrations.
• Experience improving a system with meaningful legacy code or technical debt while the product remained actively developed.
• Experience with multi-tenant SaaS architectures.
• Experience improving engineering practices across a team rather than only within your own work.
• Experience as a Senior Engineer in a company of roughly 20–200 people, where your role included helping decide what technical work actually mattered.

Required Soft Skills

• Ability to take technical ownership beyond your own tickets and think about the health of the product and engineering system as a whole.
• Strong engineering judgment and the confidence to challenge technical decisions constructively, including decisions made by Staff Engineers and engineering leadership.
• Comfort with ambiguity. Problems will not always arrive fully specified, and part of your job is asking the questions that make them clear before code gets written.
• Ability to explain complex technical trade-offs clearly to engineers, Product, and non-technical stakeholders.
• A strong teaching mindset. You explain your reasoning, document important decisions, review code seriously, and make the engineers around you better rather than becoming the only person who understands a difficult system.
• Comfortable taking leadership during difficult technical situations without waiting for someone else to define every step of the solution.
• Strong written communication and self-direction. The team is distributed across Canada and Europe with limited live overlap, so you need to communicate clearly asynchronously and drive your own work.
• Fluent English, written and spoken.

Key Responsibilities

1. Own substantial systems end to end

• Take meaningful problems that have been identified but not fully solved and work with Staff Engineers and Product to determine the right technical approach.
• Own complex initiatives from problem definition through design, implementation, migration, testing, rollout, and production monitoring.
• Design not only for the expected path, but also for what happens when something goes wrong in production.

• Remain responsible for the systems you build once they are carrying real customer data and real money.

   

2. Help strengthen the architecture of a growing product

• Work closely with Staff Engineers and the VP of Engineering on architectural decisions and technical direction.
• Understand the existing architecture and identify where today’s decisions may create tomorrow’s problems.
• Identify areas where the platform may struggle as product complexity, integrations, customers, data volume, and transaction volume increase.
• Challenge architectural decisions constructively when you see a better approach.

• Help evolve the architecture incrementally through small, safe improvements rather than unnecessary rewrites or over-engineering.

   

3. Protect correctness, reliability, and engineering quality

• Treat financial correctness as a first-class engineering concern.
• Design for reconciliation and auditability: how we prove a number is correct, understand how it was produced, and detect discrepancies before customers do.
• Use Datadog, Sentry, logs, production data, and other signals to identify recurring problems and their root causes.
• Improve observability, error handling, testing, deployment safety, performance, and operational reliability.

• Make sure recurring production problems are solved systematically rather than repeatedly patched.

   

4. Own technically difficult areas of the product

• Lead work involving complex third-party integrations, asynchronous workflows, data synchronization, reconciliation, migrations, and failure recovery.
• Design systems that behave predictably when external APIs fail, requests are duplicated, jobs execute late, or data arrives in an unexpected state.
• Work closely with Product to make technical feasibility and engineering constraints visible before implementation begins.

• Help break large technical initiatives into safe, incremental pieces that can be built, migrated, and released without unnecessarily putting the existing platform at risk.

   

5. Make the case for important technical work

• Identify technical debt, platform investment, reliability work, and architectural improvements that may not naturally appear on the product roadmap.
• Distinguish between debt that can safely remain and debt that is materially affecting reliability, engineering speed, or future product development.
• Make the business and technical case for that work using evidence rather than engineering preference alone.

• Help sequence improvements so they support product development rather than competing with it unnecessarily.

   

6. Raise the level of the engineering team

• Be a strong technical reference point for other engineers.
• Review architecture, designs, and pull requests with a focus on correctness, reasoning, and long-term maintainability.
• Explain why you would make a decision differently rather than simply leaving a verdict.
• Mentor engineers through reviews, pairing, technical discussions, and example.
• Document important knowledge and decisions so understanding stays with the team rather than with one individual.

• Take leadership when a difficult technical problem crosses multiple areas or engineers.

   

7. Remain hands-on

• Design and write production code across the backend and frontend.
• Take direct ownership of technically difficult or risky work when appropriate.
• Debug difficult production issues and establish their root causes.
• Read and understand the existing codebase before changing it.

• Build enough direct knowledge of the platform to ensure your technical decisions are grounded in how the system actually works.

   

Who this position is not for

• This is not a role for someone whose definition of seniority is simply delivering more complicated tickets. 
• If you prefer receiving clearly defined tickets and technical solutions and then implementing them, this role will probably be frustrating.
• It is not a management role. You won’t have direct reports or headcount responsibility. Leadership here comes through technical ownership, judgment, mentoring, reviews, and influence.
• It is also not a Staff Engineer role. Our Staff Engineers and VP of Engineering set the overall technical direction and architecture. You will help shape that direction, challenge it when needed, and fully own the design and implementation of substantial systems within it.
• It is not a greenfield role. You will be joining a live platform with thousands of customers and a roadmap that does not pause while technical improvements are made. Much of the work involves understanding existing systems, migrating them safely, and improving them incrementally rather than replacing them.
• If you naturally ask what happens when the system gets significantly larger, how it fails, how we know the data is correct, and what today’s shortcut will cost us a year from now, you’ll recognize the work.

Things You Should Know Before Applying

• The engineering challenge is no longer simply building features quickly. It is continuing to ship while improving reliability, scalability, architecture, and the technical foundation required for significant year-over-year growth
• There is technical debt. Part of your job is determining which debt actually matters, making its impact visible, and helping address it without stopping product development.
• Requirements will sometimes be incomplete. We expect you to help shape the solution rather than wait for perfect specifications.

• You will be expected to disagree when necessary, propose better approaches, and explain the reasoning behind them.

We Look Forward to Meeting You!

If you're excited to build strong affiliate partnerships and grow with a high-performing team, we'd love to hear from you.

We are looking for a client-facing recruiter who will take ownership of the communication between our recruitment team and our clients throughout the hiring process.

This role is a good fit for an experienced recruiter who has worked closely with hiring managers, understands how to properly intake a vacancy, challenge or clarify requirements, present candidates, collect feedback, and keep the recruitment process moving.

You do not necessarily need to come from a traditional Account Management background. We are primarily looking for someone with strong recruitment experience and significant exposure to clients or internal hiring managers.

Responsibilities

• Act as the main point of contact for clients on active vacancies.
• Conduct vacancy intake and briefing calls with hiring managers.
• Understand the business context behind each hire, not just the formal job description.
• Clarify role requirements, seniority, must-have and nice-to-have criteria, compensation, location, and other hiring constraints.
• Translate client requirements into clear instructions and priorities for the sourcing/recruitment team.
• Review and present relevant candidates to clients.
• Provide clear context and recommendations when introducing candidates.
• Coordinate interviews between candidates and hiring managers.
• Collect and structure client feedback after interviews.
• Follow up with clients to keep the hiring process moving and avoid unnecessary delays.
• Discuss candidate concerns, compensation expectations, availability, relocation, motivation, and other relevant topics with the client.
• Help identify misalignment between the market, candidate pipeline, and client expectations.
• Suggest adjustments to the search strategy when necessary.
• Maintain strong, professional relationships with hiring managers and other client stakeholders.
• Keep internal recruiters updated on client feedback, changing requirements, and hiring priorities.

What We’re Looking For

• Solid experience in recruitment.
• Hands-on experience working directly with hiring managers or external clients.
• Strong understanding of the end-to-end recruitment process.
• Ability to run vacancy intake calls independently.
• Confidence in asking clarifying questions and challenging unclear or unrealistic requirements.
• Strong communication and stakeholder management skills.
• Ability to present candidates clearly and explain why they may be relevant for a role.
• Good organizational skills and ability to manage multiple vacancies and hiring processes simultaneously.
• Comfortable working in a fast-paced recruitment environment.
• Fluent or strong professional English.

What Success Looks Like

You become the person who fully understands both sides of the hiring process: what the client actually needs and what is happening in the candidate market.

Clients trust you to understand their requirements, present relevant candidates, organize the process, and give them honest market feedback.

At the same time, recruiters internally have a clear understanding of what they should search for, why candidates are accepted or rejected, and how the vacancy is evolving.
