Department/Project Description

Our customer is an American manufacturer and globally recognized leader in Healthcare and Medical Devices. In close cooperation with the international team you will have the ability to participate in product feature definition, development, testing, and post-release support for innovative medical products.

ABOUT OUR CLIENT

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

ABOUT THE ROLE

We are looking for a Senior Software Engineer to build and operate production AI agent and search services on top of a large-scale data platform. This is hands-on work at the intersection of distributed backend engineering and applied AI: multi-agent workflows, tool-execution infrastructure, retrieval and relevance, and integrations with multiple LLM providers — all running as real, customer-facing production services with the reliability expectations that implies.

RESPONSIBILITIES

• Design and implement scalable multi-agent workflows (including conversation state), tool-execution infrastructure, and data-aware tools working with catalogs, schemas, lineage, SQL, jobs, semantic metadata, data preparation, and visualizations
• Build search and retrieval capabilities with OpenSearch or equivalent — indexing, relevance tuning, hybrid keyword + vector search
• Integrate multiple LLM/model providers with secure configuration and graceful degradation
• Develop APIs and event contracts across REST, streaming/SSE, gRPC, protobuf, and SDKs, including UI integrations
• Operate, monitor, and improve production services — service health, logs, metrics, traces, search-cluster health, latency, and error rates; participate in the team's production-support model

• Take ownership and responsibility for their work.
• Are proactive and solution-oriented.
• Enjoy learning and continuous development.
• Are curious and ask thoughtful questions.
• Work collaboratively and support their teammates.
• Respect customers and colleagues.

• Are interested in building long-term relationships rather than chasing short-term wins.

   

What the Company Offers

• A role within a product-focused IT company.
• The opportunity to contribute to the growth of an international market.
• Full product training and ongoing support from the team.
• Real opportunities for career development and internal growth.
• A culture built on trust, ownership, learning, and initiative.
• Fully remote work format.

We build and run AI agent systems for founders. Four are in production — German real estate, US legal tech, executive assistance, enterprise HR analytics — with paying clients since 2023 and revenue that renews monthly.

Every one of those clients arrived by referral. Nobody here has ever gone out and found one.

That's the seat. You'd be the first person to do outbound at this company.

What we sell

Technical ownership of a founder's roadmap and its execution, from one person. One weekly call, cancellable at the end of any month. The price is published, not quoted.

Who buys it

Two shapes, and they buy for different reasons:

• A founder with no technical half. Non-technical, or technical enough to judge the work but not to own it. Has money and a specific thing they want to exist, and nobody who can build it. This is often one person — headcount doesn't bound it
• A 3–20 person company with deep domain expertise, owner-operated, doing something valuable by hand. They know their domain better than we ever will and have nobody who can turn it into a system

What they share is that the person on the call is the one whose money it is, and that nobody inside can build the thing.

What you'd do

• Find both shapes — the second one is the half most people forget, and it's the one that's already profitable
• Verify each one against four checkable facts, before any meeting is booked
• Get them onto our founder's calendar
• Sit on the scoping call — you're on every one of them
• Target: four qualified founders a month. That's the entire KPI

What we're looking for

• 2+ years selling custom software development or dev services. Not SaaS seats, not staff augmentation
• At least one deal you closed where the signer was the founder
• You can see when a founder is about to buy, from public signals. Ours have been: money already spent on a prototype with nothing running; an engineering role open for months at a company too small to assess the candidates; the one technical person just left and the roadmap went with them. And on the domain-expertise side: a third hire into the same manual role, or an ops ad whose responsibilities read as a list of steps
• You can tell a real buyer from a curious one before we spend an hour on them
• You work without being managed. There is nobody here to check in on you, set your week, or notice you've stalled. The target is the only instruction you get
• English B2 or better

Format

• Fully flexible, your own hours, we are okay with you being employed somewhere else at the same time or running your own business
• Independent contractor, commission-based — paid per qualified meeting and per closed deal. No base. Figures and full terms come in a two-page sheet after we've talked

Aero is an international team of engineers based in Ukraine. The company was founded in August 2026 and raised its first round of capital.

We're looking for an Aircraft Designer / Aerodynamics Engineer to join the core build team and own the aerodynamic and aero-structural design of an airframe — from CFD and stability analysis through to a flying prototype and first deployments.

What you'll do

• Design and iterate the BWB airframe geometry, balancing aerodynamic efficiency, stability/control, and shaping constraints.
• Run aerodynamic modeling and simulation (CFD, stability & control, performance envelope) to support design decisions.
• Work closely with the Head of Design on composite structure, control-surface actuation, and integration with propulsion and avionics.
• Iterate quickly across a batch-build, test-and-fly development cycle rather than a single "golden" prototype.

What we offer

• A decent stock option plan, but a modest salary for the first 6-9 months (the salary will be increased as soon as we accomplish the plan);
• Opportunity to create an aircraft with unique properties, drive the product development, and grow with us;
• Work in an international team that worked on world-famous products;
• Commitment to global security;
• A lot of work and fun in your new journey with us;
• Reservation from mobilization.

What we expect

• Proven experience and excellent knowledge of the domain;
• Team members learn Ukrainian, but English is still the main team language;
• A great and open-minded human being.

Location: Kyiv, Ukraine
