What are we looking for?

We're seeking a skilled Software Development Engineer who excels in creating seamless connections between various systems and applications. If you're passionate about coding, love solving integration challenges, and enjoy working with APIs, you might be the ideal candidate.

In this role, you'll collaborate closely with our development and product teams to design and implement robust integration solutions. Your work will ensure that different systems communicate effectively, creating a cohesive and efficient technology ecosystem. Join us to build integration solutions that enhance our technical capabilities and drive business success.

Responsibilities

• Own client go‑lives:

  Translate enterprise requirements into working GenAI deployments—scoping, coding, testing, and shipping on aggressive timelines.

• Build custom integrations:

  Craft REST/webhook connectors, event pipelines, and data syncs that plug our agents into CRMs, OMS, ERPs, and bespoke systems.

• Engineer GenAI workflows:

  Orchestrate RAG pipelines, prompt chains, and fine‑tuning jobs, using tools like

  LangChain

  and

  PGVector

  .

• Design deployment architectures:

  Spin up scalable, secure clusters on AWS/GCP with

  Docker

  ,

  Kubernetes

  , and

  Terraform/Helm

  .

• Instrument & optimise:

  Track latency, token spend, and error budgets; debug across logs (Kibana), tracing, and databases to keep uptime > 99.9 %.

• Create playbooks:

  Document repeatable patterns, SDKs, and IaC modules so future deployments are faster and safer.

• Partner cross‑functionally:

  Work with Customer Success, Product, and Core Engineering to shape roadmap and close feedback loops.

Must-haves

• 1–3 years building backend/integration solutions for

  SaaS

  or platform products.
• Proficient in

  Python

  or

  Node.js

  (FastAPI/Django/Express) and strong in

  RESTful API

  design.
• Solid database chops—

  SQL
