Senior Backend Engineer (Python/Postgres)

Senior Backend Engineer (Python/Postgres)

We’re seeking an experienced Senior Backend Engineer to join our small, high‑impact engineering team. In this role, you won’t just be implementing tickets; you’ll be helping shape the core of our product as we scale from a fast‑moving startup into a durable, data‑driven platform. This position is ideal for a backend‑leaning engineer who enjoys owning features end‑to‑end, designing systems that grow with usage, and collaborating closely across with UI/UX, product, and operations.

If you’re excited about building real systems with real users, enjoy deep backend work, and want meaningful ownership in a lean environment, we’d love to talk.

Responsibilities

• Design, build, and own features with a focus on data.

• Lead backend development efforts using Python (Flask) and Postgres, with a focus on scalability, performance, and maintainability.

• Design and evolve data models as the application transitions into a system of record.

• Build and operate background jobs, async workflows, using RQ.

• Contribute to the development of role‑based access control (RBAC), permissions, and authentication systems.

• Build server‑rendered UI (Flask/Jinja2) for core workflows, and partner with UI/UX on more complex, client‑heavy interactions.

• Help mature our architecture as usage grows, balancing speed with long‑term technical health.

• Participate in code reviews, technical discussions, and architectural decision‑making.

• Communicate tradeoffs and technical decisions clearly to teammates and stakeholders.

Skills

• Strong backend engineering fundamentals with Python; Flask experience a plus.

• Deep experience designing and working with Postgres and relational data models.

• Solid understanding of RESTful APIs and service‑oriented architectures.

• Comfortable building server‑rendered views (Jinja2 or similar).

• Experience with background job processing and task queues (RQ, Celery, or similar).

• Strong problem‑solving skills and sound technical judgment.

• Excellent written and verbal communication skills.

• Ability to work effectively in a lean startup environment.

Requirements

• 5+ years of professional software engineering experience.

• Proven experience delivering production systems with Python and relational databases.

• Experience owning features or systems end‑to‑end.

• Familiarity with background processing, task queues, and async workflows.

• Experience working in small teams with shifting priorities.

Competitive Applicants Will Have

• Experience building or scaling data‑heavy applications.

• Strong SQL performance tuning and query optimization skills.

• Exposure to stats, analytics, or data aggregation workloads.

• Experience implementing RBAC or multi‑tenant systems.

• Comfort working with containerized environments and cloud infrastructure.

• A product‑oriented mindset and appreciation for good UX.

• A strong async communication style (and a respectable Slack emoji game).
