We are looking for an Integration Team Lead to own everything that connects Equals 5 to the advertising platforms. This is a technical management role: you lead a team of 2–4 engineers, own the integration architecture and roadmap, and stay hands-on in the code. Every number our clients see in a dashboard starts as an API call one of your pipelines made, so reliability and data correctness land on your desk first. You report directly to the CTO and prioritise the roadmap together with the product team. Fully remote, EU timezones.

Requirements

General

• 2+ years leading engineers as a tech lead, team lead or hands-on engineering manager: code review, sprint planning, mentoring
• 5+ years in backend or data engineering, with production systems you supported yourself
• Experience integrating third-party APIs at scale: rate limits, OAuth flows, webhooks, async reports
• Comfortable in a fully remote team with hours overlapping EU timezones
• English B2 or above. Most of our communication is written and async

Technical

• Strong Python 3.11: production-grade code with error handling, structured logging and tests
• Data pipeline patterns in practice: idempotency, backfill, incremental sync, schema evolution
• GCP at the service-design level: Cloud Run services and jobs, Cloud Functions, Cloud Scheduler, Cloud Tasks, Cloud SQL, GCS, Secret Manager
• SQL well beyond the basics, and comfort putting real logic into it. A large part of this pipeline lives in BigQuery scheduled queries and versioned BigQuery migrations rather than in Python
• Writing FRDs and keeping technical documentation current: integration contracts, data models, runbooks. We do not have this discipline today, and establishing it is a core part of the role rather than a bonus
• Monitoring and alerting you set up yourself: Grafana, logs, retry and backfill strategies. Today every alert path ends in Slack
• Docker, and CI/CD you will own. These services currently deploy from hand-run scripts with no pipeline and no tests in CI. Building that out is part of the job, not something you inherit finished

Soft

• You lead in practice: you split work for other people, review their code, unblock them, and say no when that is the right answer
• Systems thinking: you see the full chain from API ingestion to the end-user dashboard
• When a number looks wrong, you trace it back to the source before you change anything
• Task management: your roadmap and your team’s board reflect what is actually happening, and you raise risks while there is still time to act on them
• Pragmatic and transparent, including when something breaks: you say what happened and why, early

AI baseline

AI-assisted development is how we ship, not something we are piloting. Concretely, what we expect from day one:

• Daily use of AI coding agents (Claude Code, Cursor, Codex or similar): required, not “I tried it once”
• 50%+ of the code you ship is drafted by agents and reviewed by you line by line
• Able to run 2–4 agents in parallel on isolated branches or worktrees and merge the results yourself
• You maintain agent context for your projects: CLAUDE.md / AGENTS.md, custom commands, rules files. At least 1 such artifact you wrote yourself and keep current
• You automate at least 1 recurring routine per month with an agent: reports, migrations, release checks, test generation
• You can tell when the agent is wrong and throw the output away. Whatever ships, you are the engineer on the hook for it — we ask about this in the interview

Nice to have

• Hands-on experience with the Meta Marketing API or the LinkedIn Marketing API: breakdowns, attribution windows, async reports
• Experience with a workflow orchestrator (Airflow, Prefect, Temporal). We run on Cloud Scheduler and Cloud Tasks today, and we want a view on whether that should change
• The programmatic and ad-server ecosystem: CM360, DV360, StackAdapt, TikTok
• Advertising metrics and how they are computed: impressions, clicks, conversions, ROAS, attribution models
• Healthcare or pharma domain, especially consent and PII handling
• Building agent harnesses, orchestrators or MCP servers; terminal-first workflow (tmux or equivalent)
• Infrastructure as code. Our infrastructure is in Pulumi, with Terraform for the monitoring stack

Responsibilities

• Own the architecture and evolution of all platform integrations: Meta Marketing API, LinkedIn Marketing API, CM360 and DV360, with StackAdapt and TikTok in flight
• Lead a team of 2–4 engineers: code review, sprint planning, mentoring, input into hiring
• Stay hands-on: you write code yourself as well as distributing it
• Design and maintain the pipelines end to end: ad-platform APIs into BigQuery through Cloud Run Jobs, onward into ClickHouse through Cloud Functions and Cloud Tasks, with a large share of the transformation in BigQuery scheduled queries
• Keep the smaller integrations healthy too, such as the five-minute PostgreSQL to Airtable sync
• Write the FRD before an integration starts and keep the technical documentation current after it ships
• Keep sync reliable: monitoring, alerting, error handling, retry and backfill strategies
• Build out CI/CD, secret handling and test coverage for these services
• Drive new integration projects from API evaluation to production rollout
• Prioritise the integration roadmap together with the product team
• Report to the CTO and agree architecture and technical standards with them

Tech stack

Python 3.11 · GCP (Cloud Run services and jobs, Cloud Functions, Cloud Scheduler, Cloud Tasks, Cloud SQL, GCS, Secret Manager) · BigQuery, ClickHouse, PostgreSQL · Docker, Cloud Build, Pulumi, Terraform · Grafana, Slack · Claude Code

What we offer

• Fully remote with flexible hours, overlapping EU timezones for syncs
• A direct line to the CTO: you shape the architecture and technical standards of the integration layer, and technical direction is agreed with the CTO rather than handed to you as tickets
• Paid AI tooling, including Claude Code
• Ad-platform APIs that fail in ways no documentation describes, at real data volumes
• A small team with no bureaucracy, where decisions happen the same day

About us

Equals 5 is a marketing data platform for pharma. Our clients are pharmaceutical brands, and the people their campaigns reach are verified healthcare professionals. Brand teams use our platform to run campaigns across Meta, LinkedIn and programmatic channels and to measure what those campaigns did. The data infrastructure behind it runs on GCP, with campaign statistics landing in BigQuery and ClickHouse. The team is small, fully remote across EU timezones, and ships every week.

Interview process

1. Intro call, 30 min — expectations both ways
2. Technical interview, 90 min — integration architecture, API experience, data pipeline design, and how you work with coding agents
3. Conversation with our product lead, 45 min

🚀 Project Description

orthoeye.digital builds a web platform for orthodontic clinics. Doctors upload 3D intraoral scans of the upper and lower jaw. The platform prepares the scans, splits them into teeth and gingiva, and gives Doctors tools for diagnosis and treatment planning.

This role owns the backend geometry: the mesh processing that runs on our servers between scan upload and the clinical tools. A separate team works on the machine learning models (segmentation, landmarks). You use their output, but you do not train models.

Stack: Angular + Three.js SPA, Node.js/Express API, Python services, native geometry code in C++, Docker on Linux workers.
 

✅ You are:

• A Middle or Senior engineer with commercial experience in computational geometry or mesh processing
• Strong in modern C++ (C++17 or later): memory, performance, profiling, building native libraries
• Have hands-on experience with triangle meshes: half-edge or similar structures, topology, normals, boundaries, non-manifold cases
• Have implemented or integrated algorithms such as mesh repair, hole filling, remeshing, decimation, Boolean operations, offsetting, or cutting by a plane or a curve
• Have used at least one geometry library in real work (CGAL, OpenMesh, libigl, VCG, Open3D, a commercial SDK, or similar)
• Good at the math behind it: linear algebra, spatial data structures (BVH, k-d tree), numeric precision and tolerances
• Can write tests for geometry code: fixtures, tolerance checks, regression checks
   

➕ Will be a plus:

• Experience with Polygonica or MeshLib
• Python, including C++ bindings (pybind11 or nanobind), numpy, trimesh
• Background in dental CAD/CAM, orthodontics, medical 3D, or 3D printing
• Contour projection onto surfaces, geodesic paths, signed distance fields, rigid registration (ICP)
• Evaluation of third-party SDKs: benchmarks, test sets, licence terms, headless deployment
• Docker, Linux, CMake, CI for native code
• Some Node.js/TypeScript, to read how the API calls your services
• Comfortable working with AI platforms and developer tools such as Cursor, Claude Code, or Codex
   

♟️ What We Expect from You:

• Own geometry decisions from start to end: choose the approach, prove it on test data, ship it
• Set clear tolerances and quality checks, and say plainly when an operation cannot meet them
• Make practical decisions that help us launch faster without unnecessary overengineering
• Use modern AI tools, frameworks, and approaches to work faster and more effectively
• Be comfortable working in an evolving product with changing priorities and early-stage ambiguity
   

🔑 Responsibilities:

• Сompare two commercial mesh processing SDKs on the same test set and help the team select one. Build the test corpus, the test harness and the gate tests, write the decision record, and write the adapter for the selected SDK
• Build scan preparation operations: inspect and repair meshes, remesh and decimate, cut by a plane or a contour, extrude a boundary and build a model base, smooth a region within limits
• Build segmentation finalization: project tooth contours onto the jaw surface, cut the mesh into labelled teeth and gingiva, keep the labels after remeshing
• Second half of the year: geometry for orthodontic appliances (Boolean operations, offset and shell thickness, exterior envelope, distance and contact queries, registration of two surfaces)
• Make each operation run headless on Linux workers, with clear inputs, outputs and error reports
• Write tests with fixtures and tolerance checks for each operation
• Actively collaborate with the tech lead, the ML team, and the frontend developers of the 3D viewers
• Utilize AI to review pull requests and contribute to engineering best practices
   

🍩 What we offer:

• Work on an innovative product in the medical-tech domain:
  • High ownership: you make the main geometry decisions in the product
  • A fast-moving environment where strong engineers can influence product and technical decisions
• Professional development support:
  • Paid 200$+ AI assistants and modern engineering tooling
• Full-time, long-term role (we want to start as soon as possible)
• Fully remote, from any location (we work in the European time zone and need a few hours of daily overlap)
• 20 days of vacation (business days)
• 5 days of sick leave
  • National holidays covered

🗣 Recruitment process:

• ✔️ Intro Interview → ☑️ Home Coding Task → ✅ Geometry Deep-Dive Interview → 🏁 Cultural-Fit Interview

🚀 Project Description

Facie is an early-stage AI product working with face image analysis.

We are looking for a strong Junior Computer Vision / ML Engineer to build a reliable mechanism for measuring facial geometry from photos.
 

The first challenge is straightforward to describe but non-trivial to solve: given a face photo, accurately measure numerical parameters of different facial features, such as eye dimensions, mouth dimensions, nose geometry, jaw proportions, distances between facial landmarks, and other geometric characteristics.
 

This is a greenfield CV problem.

You will not receive a predefined model or a detailed list of experiments to execute. We expect you to explore several possible approaches, quickly validate them, discard what does not work, and find a solution that is good enough to move into the product.
 

At phase 1 - our engineering philosophy is simple:

20% of effort that delivers 80% of the result is often better than spending weeks searching for theoretical perfection.
 

✅ You are:
 

• Confident with Python
• Understand core Machine Learning concepts
• Have practical experience with Computer Vision OR can demonstrate serious interest in the field
• Can work with existing open-source models and libraries
• Comfortable reading unfamiliar code and quickly running existing projects
• Understand basic model inference and API concepts
• Able to turn an unclear problem into several testable hypotheses
• Comfortable when the first approach does not work
• Able to explain how you would validate whether an experiment actually works
• Focused on finding a practical solution rather than endlessly optimizing one approach
• Comfortable using Git and working with an engineering team

Commercial Computer Vision experience is not required.
 

If your primary background is general ML or software engineering, we would still like to talk if you can demonstrate genuine interest in CV through things such as:

• university or online CV courses
• pet projects
• GitHub projects
• Kaggle
• research or thesis work
• reproduced papers
• personal experiments

♟️ What We Expect from You:
 

• Experiment-first thinking - generate several possible approaches instead of betting everything on the first idea
• 80/20 mindset - optimize for time-to-market and find the simplest solution that provides enough accuracy for the product
• Ownership - do not wait for someone to define every next experiment for you
• Validation mindset - always ask how we know that a result is actually correct, especially when perfect ground truth does not exist
• Fast iteration - prototype, measure, learn, discard weak approaches and move forward
• Engineering judgment - understand when ML is needed and when deterministic geometry or conventional code is a better solution
• AI adoption - actively use modern AI coding tools when they help you iterate faster
• AI skepticism - understand and verify AI-generated code instead of blindly trusting it
• Clear communication - explain what you tried, what failed, what worked and what you recommend trying next
   

🔑 Responsibilities:
 

• Research different approaches for measuring facial geometry from images
• Build quick prototypes and experiments
• Evaluate existing Computer Vision models and open-source solutions
• Compare multiple approaches using measurable criteria
• Design practical validation methods when perfect ground truth is unavailable
• Analyze failure cases and identify why particular approaches fail
• Select solutions based on accuracy, complexity and time-to-market
• Build a reproducible facial geometry measurement pipeline
• Document experiments, conclusions and technical decisions
• Prepare successful solutions so they can be integrated by Software Engineers
• Ideally, help turn successful prototypes into an inference service or API

🤖 AI-assisted Engineering
 

We actively use modern AI development tools.

You are welcome to use Cursor, Claude Code, Codex or similar tools to write code, explore libraries, integrate models and accelerate experiments.

We do not care whether every line of code was written manually.

We do care whether you understand:

• what you are testing
• why you selected a particular approach
• whether the result can be trusted
• how you validated it
• what the generated code actually does
• what you would try next if the approach fails
   

🍩 What We Offer:
 

• Part-time or Full-time depending on the candidate
• Remote work
• A real Computer Vision problem with direct impact on the product
• Significant ownership of the CV direction

🗣 Recruitment Process:
 

Intro Interview → Live Problem-Solving Session → Small Practical Experiment → Final Interview
 

💻 Live Problem-Solving Session (Optional)
 

This is not LeetCode and not a theoretical ML exam.

You will receive a previously unseen Computer Vision problem and will be asked to think aloud and visualize your approach using a whiteboard, Paint, FigJam or a similar tool.

We want to understand:

• how you decompose an unclear problem
• how many reasonable approaches you can generate
• what you would test first
• how you prioritize experiments
• how you validate results
• what you do when the first few approaches fail
• when you decide that a solution is good enough to ship
   

🧪 Practical Experiment (Optional)

Selected candidates will receive a small Computer Vision experiment.

You can use:

• AI coding tools
• Google
• documentation
• open-source models
• existing libraries
• research papers

We are not testing your ability to code without assistance.
 

We are testing your ability to turn an ambiguous CV problem into a working and validated solution quickly.
 

The expected output is a small working prototype plus a short explanation of:

• approaches considered
• approach selected
• why it was selected
• how the result was validated
• discovered limitations or failure cases
• what you would try next with one additional day
