Senior Engineer - Product and Platform Engineering

Technical areas to assess (from client JD):

• C# .NET — primary language; must be strong, not just familiar

• AWS (ECS / EKS) — containerization experience is a strong plus

• Bitbucket — source control

• Jenkins / Argo / Octopus — CI/CD pipeline tooling

• PagerDuty, Coralogix, Grafana Cloud — monitoring & ing; production support awareness

• Jira, Confluence — delivery and documentation tooling

• Databases: SQL Server, DynamoDB, Postgres, MySQL

• Queuing: SQS, SNS, RabbitMQ, Kafka

• gRPC, REST APIs; batch processing awareness

• OOP paradigm; observability practices

• All roles are backend only — no front-end skills required

1. Ownership & Autonomy

• There are no separate testers and no pre-written specs; engineers own the full dev lifecycle
• Must self-unblock; passively waiting on a blocker is a disqualifier
• Should be comfortable pairing with Product and driving their own delivery
• Actively participating in the team discussions (involved in discussions and offering an opinion)

2. Curiosity & Learning Mindset

• Must be willing to navigate complex, undocumented legacy code
• Should be actively using or exploring AI tools (Copilot, etc.)
• Openness to modernization and new technology is important

3. Communication & Participation

• Comfortable reaching out to unfamiliar people for help
• Active contributor in team discussions, not a passive participant
• Pair programming is expected, especially during ramp-up

4. Enthusiasm & Drive

• Genuine passion for engineering, not just task completion
• Must want to improve and modernize things, not just maintain them

Experience bracket:

• 4–6 years preferred (mid-level to early-senior)
• Client's note: engineers with 10+ years tend to be less adaptable in this environment
• Payments domain experience is a bonus, not a prerequisite
