Job Description
OUR HIRING PROCESS:
- We will review your application against our job requirements. We do not employ machine learning technologies during this phase as we believe every human deserves attention from another human. We do not think machines can evaluate your application quite like our seasoned recruiting professionals—every person is unique. We promise to give your candidacy a fair and detailed assessment.
- We may then invite you to submit a video interview for the review of the hiring manager. This video interview is often followed by a test or short project that allows us to determine whether you will be a good fit for the team.
- At this point, we will invite you to interview with our hiring manager and/or the interview team. Please note: We do not conduct interviews via text message, Telegram, etc. and we never hire anyone into our organization without having met you face-to-face (or via Zoom). You will be invited to come to a live meeting or Zoom, where you will meet our INFUSE team.
- From there on, it’s decision time! If you are still excited to join INFUSE and we like you as much, we will have a conversation about your offer. We do not make offers without giving you the opportunity to speak with us live.
INFUSE is committed to complying with applicable data privacy and security laws and regulations. For more information, please see our Privacy Policy
This is a “build and lead by doing” role. You will define architecture and standards, deliver features end to end, and consistently raise the bar for reliability, security, and delivery speed.
What You’ll Do:
Reliability, Security & Ops
- Harden CI/CD (GitHub Actions or Jenkins); build/test containers and deploy via Helm to AWS (EKS or ECS).
- Add lightweight bot protection: rate limits, IP allowlists, and abuse detection hooks.
- Observability: monitor latency/error budgets via CloudWatch + Grafana, structured logging, tracing where needed.
- Performance tuning: DB indexes, caching strategy, queue throughput, API response times.
Tech Lead Responsibilities
- Own architecture decisions and keep it pragmatic: “simple first, scalable where it matters.”
- Drive code quality: reviews, standards, branching/release hygiene, definition of done.
- Break down work, reliably estimate, unblock the team, and align with the PM/BA on scope.
- Mentor engineers and set a strong engineering culture around clarity and ownership.
Required Stack:
Must-have
- .net
- PostgreSQL, Redis, MognoDB
- OpenAPI 3, GitHub Actions
- Queues & scheduling: SQS, EventBridge/Lambda, or Celery
- 3+ years building production systems; 2+ years in a lead/ownership role.
- Real experience running things in production: CI/CD, Docker, monitoring, and incidents.
- Deep understanding of RBAC, session/auth flows, and security basics (OWASP-minded).
- Comfortable with async/event-driven patterns: queues, schedulers, retries, idempotency.
- Clear documentation, good tradeoffs, and keeping stakeholders in the loop.
- Upper-intermediate level of English or higher.
- Fluent Ukrainian and/or Russian language.
Nice-to-have
- Background in RPA, UiPath, browser automation, or similar automation-heavy environments.
- Experience with AI / ML / LLM-enabled products, data extraction, or workflow automation.
- Python backend experience (FastAPI, Flask, or similar)
