Jobs

We are a senior engineering team hiring a backend engineer for a long-term role inside a client's product team. The client is a product company with a large user base. We share its name only with engineers who pass our technical call.

Engineers there shape what gets built, not only how, and work directly with product people.

The product's image and video generation runs on ComfyUI workflows, so hands-on ComfyUI is a must for this role.

What matters most to us
• You have built or run ComfyUI workflows yourself, with models deployed locally and custom nodes in the pipeline
• You have built a product that people use every day, and you can point to the parts you owned
• You think about the person using the product. You question a feature when it does not serve them and suggest a better one
• Experience with consumer products built around image or video is a strong plus

What you will do
• Build and run ComfyUI workflows for image and video generation
• Build and scale the backend services around them in Go
• Run background jobs reliably, with queues, retries and idempotent steps
• Turn new models into features people actually use

You should have
• Hands-on ComfyUI, at least on your own projects
• 3+ years of Go in production and 5+ years of backend work overall. 
• Experience owning parts of a production system end to end
• Fluent English for daily work with the client team

The role is full time, 40 hours a week, long term, with a working day that overlaps European business hours. Individual engineers only, no agencies.

How we hire: a call with our CTO about your ComfyUI work, your product work and your code, then a call with the client's team. Both are live, with screen share and without AI assistants.

To apply, open your application with a link to a ComfyUI workflow you built or ran, or one sentence on what it did. Applications without it will not be read.

You’ll Do Well Here if You Are

• A doer. You see something broken and fix it. You'd rather move on clarity than wait for certainty.
• A fast learner who knows you don't know everything. The AI landscape changes weekly. You're senior enough to know better and curious enough to keep learning anyway.
• Direct in a way that makes the work better. You give honest feedback. You'd rather have the hard conversation than blow smoke.
• Obsessed with craft. You know genius is in the details. You ship exceptional, not perfect, and you don't put your name on work you wouldn't stand behind.
• Built for ownership. You honor commitments, admit mistakes fast, and back your teammates when a decision costs something. No handoffs, no finger-pointing.
• All in. You treat clients' businesses like your own. You take the work seriously without taking yourself seriously.

Our client is a fast-growing, well-funded startup building the AI-native ERP for modern finance teams. Every business needs a financial system of record, yet the world’s largest fintech market ($220B+) still runs largely on software from the 1990s. Their platform automates accounting from data entry all the way to close, so finance teams move faster, spend less and take on less risk.
 

In just two years they’ve raised $100M+ from top-tier venture capital and growth investors, and work with customers ranging from $5M ARR startups to publicly traded companies.
 

They hire outliers: people who have achieved difficult things, in their careers or beyond. The team includes former competitive athletes at the highest level of their sport, Broadway performers, people who trained with UFC champions, and the founder of one of the country’s largest Python communities.
 

This is a confidential search. The company name will be shared with shortlisted candidates ahead of interview.

Nice to have:

• Accounting, ERP or fintech knowledge: double-entry, chart of accounts, close, AP/AR, revenue recognition.
• Prior forward-deployed, applied or special-projects experience.
• Judgment about when to ship a script versus build a system.
   

Benefits

• Join early in one of the fastest-growing AI companies in finance and grow with it.

Department/Project Description
We are seeking an expert Data/Backend Infrastructure Engineer with strong distributed systems experience, large-scale data processing, cloud-native architecture, data lake/table formats, query engines, and production systems engineering.

Cider Consulting is a U.S.-based software consultancy. For more than 15 years we have built custom software for clients across the U.S. However, AI has changed how software is built and what clients expect, that’s why we are moving to one person per client project. We call them Solo Solutions Drivers. This SSD owns the client from the first discovery conversation to a working, adopted solution built with AI. This changes what we need from our people, and how we find and keep them. That is why we are hiring a Director of People.

The Role

You get real ownership and high autonomy and a chance to build the people's side of a new model from the start. How Cider finds, assesses and keeps Solo Solutions Drivers is still open, and you will shape it. Some HR practices already exist, and you decide what to keep, what to build, and what to adjust. There is no heavy corporate structure. You will be the main People leader at Cider, working directly with the executive team and the Technical Director. Our immediate focus is:

• Recruitment: The SSD is a new kind of role, and few people on the market match it. For the first months, actively find the SSDs yourself, and design how we attract, assess and hire them across the US, Europe, Ukraine, etc. The HRD role is hands-on: you run searches, screenings and interviews yourself. 
• Assessment: build practical ways to assess people, and help our managers use them.
• Retention and development: shape how we engage, develop, and keep people.
• Leadership: you sit at the table for the most important people's decisions and help decide where the company should focus.
• Our later focus will be: as our focus changes, you take on broader HR work such as onboarding and offboarding, learning and development, compensation, team engagement and vendor relations and other strategic-related activities to decide what the company’s areas of focus should look like in order to best utilize strengths to serve the market.

Who we are looking for

This is probably you if:

• You have recruited technical people yourself, and closed roles that are not typical on the market. You can tell us about one such search and what you did.
• You know how software is built. You have worked in the software world, you can say what you were personally involved in.
• You can explain what you built or improved. You can describe your own part and the value it created for your company.
• You are a people person who gets results. You care more about finding and keeping the right people than about designing policies and structures.
• You can fluently communicate in English (C1-C2 English).

Hiring Process

• Intro call (30 minutes) with the HR Coordinator. We tell you more about the role and the team, and you tell us what you are looking for. We also check that the role and your expectations match.
• Interview with the Technical Director and the HR Coordinator (1 hour). We talk about your experience in more detail, and you can ask us more detailed questions about the company and the role.
• Interview with the executive leader you would report to (1 hour). You talk about how you would work together and how you approach people and retention.

Working Model

• Location: Fully remote
• Timezone: Part of the team you will work with is based in New York, while the other part is based in Europe.
• Meaningful working-hour overlap with both is required.
• Engagement: B2B contract. Full-time.
• Benefits: after 6 months working with us you will get 15 PTO days per calendar year.

Please share your CV along with a link to your Portfolio.

What We Offer

• 100% remote work opportunity and flexitime - choose working hours between 8:00-20:00 Kyiv time.
• Personal Growth Budget in USD (Travel, Health & Psychotherapy, Sports, Education & Training, Software, Work Equipment).
• Competitive compensation in USD with regular salary reviews.
• Paid vacation, holidays, and sick leave.
• Continuous professional growth through mentorship, feedback, and knowledge sharing.
• English Speaking Club with a native speaker.
• Access to AI tools, including coding assistants for engineers and LLM subscriptions for non-technical specialists.
• Projects with clients across Europe and North America across FinTech, Logistics, Hospitality, E-commerce, Legal, Music, and other industries.
• Transparent processes, flat management structure, and a supportive team culture.

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.
