Senior Integration Engineer

Requirements:

• 6 years of experience building and operating backend or integration services in production.
• Proven end-to-end ownership from designing and building to shipping and operating systems.
• Strong hands-on experience with AWS serverless and messaging services including SQS/SNS Lambda S3 EventBridge Step Functions API Gateway CloudWatch and Secrets Manager.
• Strong backend engineering experience with TypeScript Python or a similar modern language.
• Go experience is a plus but not required the candidate should be able to learn it quickly and contribute to our tooling.
• Strong knowledge of integration and messaging patterns including idempotency deduplication ordering dead-letter queues replay retry/backoff and fault tolerance.
• Strong experience with JSON XML/XSD and CSV including parsing validation transformation and mapping.
• Solid API skills including designing and consuming REST APIs along with practical experience with partner integration requirements such as SOAP SFTP and batch files.
• A track record of mentoring or leading engineers and raising the teams engineering standards.
• Strong problem-solving and debugging skills with the ability to trace failures across multiple systems and identify the root cause.
• Experience with structured logging monitoring and building observable systems.
• Genuine hands-on use of AI tools in real engineering work with a clear understanding of where they add value and where they do not.
• Production Go experience is a plus.
• Experience with PHP as several existing integrations use it and will need to be maintained and gradually migrated.
• Experience with a transformation language such as XSLT or DataWeave.
• Experience with Infrastructure as Code including Terraform CDK or CloudFormation and CI/CD pipelines.
• Experience with streaming and storage technologies beyond the basics including Kinesis DynamoDB and OpenSearch.

• Experience in AgriTech IoT supply-chain systems or enterprise integration platforms such as MuleSoft Boomi or Camel is a plus.

Responsibilities:

• Design build test deploy and operate event-driven services using AWS services such as SQS/SNS Lambda EventBridge Step Functions S3 and API Gateway.
• Extend the canonical data model with Mykola to standardise data from multiple sources into one consistent internal representation.
• Build connectors that ingest from and deliver to external partner systems transforming data between source canonical and destination formats with schema and business-rule validation.
• Design reliable integrations with idempotency deduplication ordering dead-letter queues replay retry/backoff and fault tolerance ensuring delivery remains reliable when external systems are unavailable.
• Ship VetLink and subsequent integrations end to end including design development testing deployment monitoring documentation and operational runbooks.
• Maintain and modernise existing integrations including government/compliance APIs IoT feeds supply-chain partners and third-party software with some legacy integrations written in PHP.
• Review pull requests set engineering standards unblock the two mid-level engineers and contribute to their growth within the team.
• Build and maintain systems with strong structured logging monitoring observability and debugging capabilities.
• Investigate production issues across multiple systems and trace failed messages to their root cause.
• Use AI tools hands-on in real engineering work applying sound judgment about where they help and where they get in the way.
